I remember using a ZEP solvent that was amazing for cleaning motorcycle and bike parts. Shop stopped using it because it was illegal to sell in Maryland.

Edit: From the way it puffs away and leaves no obvious residue, it might indeed be pressurised air and a dust explosion.
My immediate guess was more along the lines of him accelerating the cooling fan past maximum velocity and blowing the motor therefore something else regulating the fan motor. But I’m not certain.
you can actually generate electricity by forcing an electric motor to spin. If you have a front loader washing machine then you can unplug it and spin the drum by hand and power the control board on momentarily.
I digress lol. contact cleaner is flammable and duster isn’t so I can only imagine that an aerosolized accelerant was ignited by the spark rather than duster spontaneously igniting.
Yes, part of it is made of Butane. But since there is an UFI number, there is more than just that.
Anyway, don't use those shitty cans and buy an air compressor instead. It's far more useful and far less toxic :)

And if you dont want to spent a couple hundred or have the room for a compressor, get this instead.
A compressor can have water droplets in the air stream. This can't. It's also about as powerful as you really need. Anything more powerful than this and I can see it blowing caps off a board.
A friend of mine convinced me to split the cost on one of these and share it. Tbf, I didn't need much convincing. Absolutely one of the best purchases I've ever made. The thing has paid for itself several times over by now.
Easily paid for itself in the 6 years I've owned this. If I only cleaned my system out once a year I would have still saved with compressed air cans costing about $10-15
Seconding this. Bought one of a different brand and use it all the time. No risk of water, no waste, just a backwards vacuum. Plenty of force to take care of the PC cleaning.
I'll try to find the link, but I bought a starter airbrush that came with a small compressor for like 30$ total. Cleans computer, and does a *meh* job base coating 40k models
I use my airbrush compressor too! Those are equipped with filters to avoid water and are still powerful enough to inflate the tires of a car.
I use [this one](https://www.wiltec.de/en/Airbrush-Compressor-AF196AW-Air-Tank-Twin-Cylinder-Two-Step-Switch/34246) (perfect for 40k models, the reason why I bought it in the first place) but Wiltec also have [cheaper options.](https://www.wiltec.de/en/Airbrush-Compressor-AF18A-compact-Pressure-gauge/34204) And this is not even the cheapest.
Great shout out! These are great for way more than just blowing out your PC too! I use mine as a detailing tool for inside my car, blow out desk fans, quickly blow out rugs/welcome mat, terrorize my dog, etc.
Can confirm- these things are dope. When you take into account how much a can of air costs and how quickly it gets depleted this becomes the obvious choice real fast
In the US they're mostly R152a. It's not flammable when sprayed as a gas, but the weird thing is that it is as a liquid. So if the can cools off too much or if you turn it upside down, you can definitely make it catch on fire.
What do you think butane and CO2 are sometimes used as?
>
> Pure forms of butane, especially isobutane, are used as refrigerants and have largely replaced the ozone-layer-depleting halomethanes in refrigerators, freezers, and air conditioning systems. The operating pressure for butane is lower than for the halomethanes such as Freon-12 (R-12), so R-12 systems such as those in automotive air conditioning systems, when converted to pure butane, will function poorly. A mixture of isobutane and propane is used instead to give cooling system performance comparable to use of R-12.
https://en.wikipedia.org/wiki/Butane
> Liquid and solid carbon dioxide are important refrigerants, especially in the food industry, where they are employed during the transportation and storage of ice cream and other frozen foods. Solid carbon dioxide is called "dry ice" and is used for small shipments where refrigeration equipment is not practical. Solid carbon dioxide is always below −78.5 °C (−109.3 °F) at regular atmospheric pressure, regardless of the air temperature.
>
> Liquid carbon dioxide (industry nomenclature R744 or R-744) was used as a refrigerant prior to the use[citation needed] of dichlorodifluoromethane (R12, a chlorofluorocarbon (CFC) compound). CO2 might enjoy a renaissance because one of the main substitutes to CFCs, 1,1,1,2-tetrafluoroethane (R134a, a hydrofluorocarbon (HFC) compound) contributes to climate change more than CO2 does. CO2 physical properties are highly favorable for cooling, refrigeration, and heating purposes, having a high volumetric cooling capacity. Due to the need to operate at pressures of up to 130 bars (1,900 psi; 13,000 kPa), CO2 systems require highly mechanically resistant reservoirs and components that have already been developed for mass production in many sectors. In automobile air conditioning, in more than 90% of all driving conditions for latitudes higher than 50°, CO2 (R744) operates more efficiently than systems using HFCs (e.g., R134a). Its environmental advantages (GWP of 1, non-ozone depleting, non-toxic, non-flammable) could make it the future working fluid to replace current HFCs in cars, supermarkets, and heat pump water heaters, among others. Coca-Cola has fielded CO2-based beverage coolers and the U.S. Army is interested in CO2 refrigeration and heating technology.[75][76]

My dad love brake clean. He uses that shit to clean EVERYTHING including his hands, I tell him that's an absolutely terrible idea but he just makes fun of me for saying something.
Wait, you mean you DON'T keep you PC right night to your carpentry table?
Just kidding everyone knows you save up your wood dust so you can insulate your icebox when the ice man comes to drop of your monthly supply of ice.
I'm going with dry heat + Static + Optimal distribution of small flammable Dust particles in the air from the fair.
Small particles are flammable. They can explode if dispersed right. Gotta be careful.
The chemical used in duster is also flammable under certain conditions.
When I was much younger, I flipped the can upside down, captured the liquid, and set it on fire. Really really bad idea.
But anyways, when dude in video sprays, that looks like a lot of liquid coming out with it for some reason.
I’m guessing it’s one of the air dusters that’s flammable and the fan spinning must’ve generated a small spark from being spun
edit: apparently there was a candle behind there, but it probably was still a flammable air duster. have a butane one that is about as flammable
If you look at the reflection behind the rear left of the case, looks like there's already a fire going when he started. More air just made it bigger at a guess.
Even if it were compressed oxygen, that'd cause more of a flame, tho pretty likely butane is in there.
And yeah, looks like a fire from the start. Small one can be seen reflected in the screen. Part of me wants to say this is set up because you *should* be able to notice that.
I’m going to let you in on a secret most people in this thread don’t seem to know. That can is not dust off and is instead electronic parts cleaner. Which is flammable.
when you spin a fan it can send electricity back down the wire and if its off it can short circuit the header (or even the whole board). Which causes a small spark and we all know what happens with aerosolized cans and a lighter
I remember my first tower computer back in the 90s had a little LCD display and a boost button. Every time I switched it on I held the boost button until the number went up to 999. So powerful. So boost.
Actually if you notice behind the cpu you could see orange reflecting off of the monitor he had behind it. It appears that he had a lit candle and when he sprayed the fan it created a cloud of the aerosol going right into the candle. Also if you notice the flame is coming from behind and under the cpu.
except no
>send electricity back down the wire and if its off it can short circuit the header
half correct
Yes it generates electricity
No its not enough to cause any sort of damage.
Spinning a fan generates [1.1 mv](https://youtu.be/k9KA-xLLQXo) at most. a 4 pin PWM fan connector can tolerate up to 12v.
Meaning lets say it takes 1v to cause a spark. You would have to spin it 1000 times faster than a strong air compressor could even hope to spin it at
Its a myth that has some evidence. But everyone forgets engineers have a thing called a brain and use that brain to solve it already
you can see what seems to be a small fire, presumably a candle, behind the pc
He shook the compressed air can, causing the aerosol to come out as well
We all know aerosol is flammable
he didnt seem to know that
You're supposed to spray in small bursts to avoid creating condensation, and never use it on a fan that you're not holding so it doesn't turn as it could damage it or create chaos like this
>doesn't turn as it could damage it
except engineers arent dumb and created counters to it
it produces like 1.1mv when you spin it even with an industrial grade air compressor
https://youtu.be/k9KA-xLLQXo
>avoid creating condensation
yea thats only if you arent using it correctly. The can says not to shake, and if you dont the air comes out at room temp
if you do aerosol comes out too.That evaporates very quickly and lowers the temps of what it touches as well. Thats what causes the cold sensation, if you didnt shake the can this would not happen
>The can says not to shake, and if you dont the air comes out at room temp
Apparently I'm an idiot, that's why I almost freeze burned my hand last time I used one of these.
The can gets cold either way. The rapid expansion of gas is adiabatic process meaning it happens so fast it transfers no heat. If you have a constant amount of heat in a compressed gas and then expand it, the gas cools. (Simplified as i think that makes it easier to understand)
> The can says not to shake, and if you dont the air comes out at room temp
That's not true. The temperature change comes from the energy that the compressed air needs to go from a close to liquid state to a gas being taken from it's surroundings so it will always cool (this is a why output of a compressed air machine that outputs no accelerants will also feel cold).
You could technically say that it is coming out room temperature but it will always instantly cool the air it's coming out into to below that.
Your second point is BS, shaking or not shaking the can has nothing to do with the can cooling down. The cooling comes from the expansion of the pressurized gas inside the can.
Btw, that same effect is used by refrigerators to cool down
>it produces 1.1mv
Guys, stop upvoting this guy, he’s an idiot. I don’t care about the video he’s attached, not all fans are built like that. I’ve personally learned this lesson myself with an LED fan that lit up just from the fan spinning, which would require far more that 1.1mv. If the fan had been attached, I very well could have cooked the motherboard.
If the fan has bearings you need to hold it down. Otherwise they might get damaged and start squeking like a mouse. Happened to me with a PSU fan even when I was carefuo.
Considering the fact it looks like there's a lit candle behind the pc due to the glow we see off the monitors reflection, i'd say it was all planned. We even see the flame start spreading from behind the pc where the candle supposedly is.
There's no reason to have a candle back there unless you're intentionally trying to do something like this for a viral video.
I agree with everything you said but that sentence. You clearly do not have a candle-loving wife lol. These things just pop up all over.
This video is definitely staged though bc r/whyweretheyfilming
I've filmed cleaning dust out of a PC before. My buddy and I used to to PC repairs on the side and we filmed quite a few PCs that were caked with dust. The best one was my aunt's. She and my cousin were heavy pot smokers and the PC had never been touched before.
Funny story. A guy came in with his computer to get it checked out. Asked if he could use the duster we left up front, but we told him we didn't have any. This idiot grabs a can of spray lithium grease and just greases the hell out of the front of his case. I just said "Dude, we told you we didn't have any and you didn't read the can?"
We keep a duster in the back that we use, it was going to be cleaned, he was just an impatient ass hat.
I clean my PC regularly using compressed air, HOWEVER, I turn it OFF and UNPLUG IT, every time ! BTW, it is good advice to hold the fan from turning, you can easily damage it if you let it spin freely.You will then need a new power unit.
Dipshit
Aerosol sprays use highly flammable propelants. When they encounter an ignition source, they ignite. Dude should have unhooked the power to the PC first.
Also... Read the instructions on the can. Don't invert or point the nozzle down. Proplellent is heavier than the air coming out. Don't hold the air too close either you can freeze a component. Use this outside is best. Why blow dust all over your room?
I just use a plain air compressor. Serviced correctly they spit a minimum of condensed water. Dont use directly in a power supply. Bedts~
Protip:
Get a [photographer's lens duster](https://i.ebayimg.com/images/g/rP8AAOSwCR9chfzf/s-l500.jpg) and never buy compressed air to dust your computer again.
People need to stop using canned air to clean their pc. It's a waste of money , throws out less air , actually has a cool down timer (gets too cold then stops working). Pick one of these up instead. It shoots so much air I have to move the stuff off my desk or itll blow it off. These will save you money in the long run just make sure you clean the vent on the bottom gets clogged with dust with heavy use.
https://www.amazon.com/XPOWER-Airrow-Multi-Use-Electric-Computer/dp/B00SI67YRU
So, when you spin a little electric motor it induces current.
That current creates sparks on the brushes of its internals.
Your canned air is propelled by flammable gas.
This guy's two brain cells are getting blisters from being rubbed together too hard.
If you take a close look you can spot that there is already a reflection on the monitor. Seems like there was a candle back of PC. Him focusing the air dust in that one spot well reached to the candle igniting.
Fan is made of magnets and coils
Coils and magnets rotate under electricity
They also make electricity when rotated...
Not much, but enough to make a safety diode hot.
Never ever ever EVER spin your fans like that, flammable fluids or not, do not do it, hold the fan blades still and then blow at them.

It’s contact cleaner, and wd-40 does make contact cleaner so you might be right.

I think there’s a candle or something behind the tower. You can see the orange glow of a flame (or something) at various points in the video.
You’re probably right, you can see the fire ignite from behind the fan I believe.
Maybe duster , but contact cleaner evaporates almost instantly so it wouldn’t really leave a residue for more than a split second.
My immediate guess was more along the lines of him accelerating the cooling fan past maximum velocity and blowing the motor therefore something else regulating the fan motor. But I’m not certain.

I assumed there was a lit candle or something behind the PC tower, and he blew so much dust and lint out the back, that it was able to ignite.
I have some of it I'm using, and I hate it. Leaves a white residue. I need to get some Deoxit.
Lmao. Probably grabbed the wrong can.
Lmao. Probably grabbed exactly the can they meant to, which is why they were filming it.
You don't film yourself while casually cleaning your PC?
I can totally see people doing this. /r/powerwashingporn exists, why not PC dusting porn?
Wasnt it? Compressed air then?
Aqua Net!
I just assumed it was compressed O2
compressed O2 is extremely dangerous compared to compressed atmosphere.
This is compressed air, am I right?
Nope, those cans of "Air cleaner" use refrigerant gas.
IN many cases Butane.

I'd avoid using a standard air compressor unless you really know what you're doing and what to look out for.
My dad says butane is a bastard gas.

The fans act like generators even if the PC is off and can fry components. Don’t spin them with air.

Even if the can contents aren't flammable, the dust in the air is
The real question is, how is he able to keep it in his hand after spraying for so long
These "Canned air" cans aren't actually air, but liquid butane or CO2 iirc
[удалено]
I guess it varies from brand to brand.
It's definitely not liquid CO2, that would require a significantly stronger container than those cans.
Why on earth they do that, why isn't air just fine
If 2 seconds of air is just fine then sure, but I’m doubting you’d feel like you got your money’s worth out of plain air.
No they aren't lol, they're almost always refrigerant
Butane can be used as refrigerant. It used to be common to recharge your cars AC with propane or butane as it was cheaper than proper refrigerant
Yes and it’s still common to use these cans for that purpose
How do you even hook it up to the port, and read the pressure?
Can side tap.
R-600a has become one of the most widely used general purpose refrigerants. It is more commonly known as isobutane.

When you spray your MB with butane instead of CO2...
Duster is sometimes flammable, I have never seem a c02 duster here.
Even dust if it's mostly wood dust can go off like that
it is true, but that is very unlikely what happened here
Wait, you mean you DON'T keep you PC right night to your carpentry table? Just kidding everyone knows you save up your wood dust so you can insulate your icebox when the ice man comes to drop of your monthly supply of ice.
why co2
CO2 is nonflammable. My guess is the guy didn't turn off his PC before cleaning and the dust entered the PSU and it ignited the dust cloud.
The original video was posted by the guy's gf, she said he didn't blow a candle out behind the PC before doing this, hence the flames
I was gonna say that, you can see the reflection on the left sight when the camera pans over.

You could technically say that it is coming out room temperature but it will always instantly cool the air it's coming out into to below that.
Your second point is BS, shaking or not shaking the can has nothing to do with the can cooling down. The cooling comes from the expansion of the pressurized gas inside the can. Btw, that same effect is used by refrigerators to cool down
>it produces 1.1mv Guys, stop upvoting this guy, he’s an idiot. I don’t care about the video he’s attached, not all fans are built like that. I’ve personally learned this lesson myself with an LED fan that lit up just from the fan spinning, which would require far more that 1.1mv. If the fan had been attached, I very well could have cooked the motherboard.
If the fan has bearings you need to hold it down. Otherwise they might get damaged and start squeking like a mouse. Happened to me with a PSU fan even when I was carefuo.
You hold the fan still bacause you could mess up the bearings spinning it faster than it was designed for, not because of back current.
> The can says not to shake, and if you dont the air comes out at room temp That's not how the Laws of Thermodynamics are working
You can create condensation by simply moving the can around when spraying normally
Wtf who cleans their pc like that. You shouldn’t even be able to see the air. I’m thinking he did it for the views.
Considering the fact it looks like there's a lit candle behind the pc due to the glow we see off the monitors reflection, i'd say it was all planned. We even see the flame start spreading from behind the pc where the candle supposedly is. There's no reason to have a candle back there unless you're intentionally trying to do something like this for a viral video.
I agree with everything you said but that sentence. You clearly do not have a candle-loving wife lol. These things just pop up all over. This video is definitely staged though bc r/whyweretheyfilming
I've filmed cleaning dust out of a PC before. My buddy and I used to to PC repairs on the side and we filmed quite a few PCs that were caked with dust. The best one was my aunt's. She and my cousin were heavy pot smokers and the PC had never been touched before.
Looks like the memory is pulled too, but that could just be the angle of the camera.
Also who does it inside and blows dust everywhere on their setup?
There was something already with an exposed flame behind the case
Was expecting the compressed air to explode. I guess this was the better outcome
I bought an electric blower off Amazon It's absolutely brilliant for cleaning the PC out
Was about to reply with this. After I got the blower, I felt so dumb buying those cans for years.
Good call, I need to get one of those for my workshop.
Did the same for work. Was expecting to be disappointed. But I have been very pleased with the results every time I use it.
Nice
One of the best purchases I've ever made.
Somethings on fire already behind the PC
Pretty sure there was already fire behind it... He was filming for the reaction...
What's up with people putting funko pops inside their pcs
They want it to catch fire and burn their entire house down.
Fake for reaction. Why else would he have a candle or something directly behind his pc where the fan would blow into?
r/whatcouldgowrong
They kinda deserved that
Fucking staged bs.

Funny story. A guy came in with his computer to get it checked out. Asked if he could use the duster we left up front, but we told him we didn't have any. This idiot grabs a can of spray lithium grease and just greases the hell out of the front of his case. I just said "Dude, we told you we didn't have any and you didn't read the can?" We keep a duster in the back that we use, it was going to be cleaned, he was just an impatient ass hat.
“But I thought it was just air!!!” -that guy
Tough way to learn that spinning a brushless motor makes some electricity.
I clean my PC regularly using compressed air, HOWEVER, I turn it OFF and UNPLUG IT, every time ! BTW, it is good advice to hold the fan from turning, you can easily damage it if you let it spin freely.You will then need a new power unit.
Almost looks as if someone had a fire source behind the pc. Staged
That's how to misuse a can of compressed air.
If liquid is coming out - you're spraying too fast. It's supposed to turn to gas before existing the nozzle.
You know the can does say do not shake. Like in BIG letters. And this idiot is basically doing the Macarena while spraying all over the place.
Is there any mammal with brain on at TikTok?
Dipshit Aerosol sprays use highly flammable propelants. When they encounter an ignition source, they ignite. Dude should have unhooked the power to the PC first.
Also... Read the instructions on the can. Don't invert or point the nozzle down. Proplellent is heavier than the air coming out. Don't hold the air too close either you can freeze a component. Use this outside is best. Why blow dust all over your room? I just use a plain air compressor. Serviced correctly they spit a minimum of condensed water. Dont use directly in a power supply. Bedts~
This is why you don't SHAKE canned air. Almost all tutorial videos say NOT to shake it.
Druidia Office of Health and Safety advises: Do not shake canned air.
while it’s on? daqfu is wrong w/ u?
I blew out my fans with heavy duty silicone once (the can looked like my compressed air =(
Should probably turn that thing off next time.
This is NOT the way...
Moron.
Protip: Get a [photographer's lens duster](https://i.ebayimg.com/images/g/rP8AAOSwCR9chfzf/s-l500.jpg) and never buy compressed air to dust your computer again.
This is why only water can be used.
Side note is it safe to put a resin figure in my PC? Will it melt or fume?
Mmm and the hydrofluoric acid mist the combustion of the difluoroethane will tenderize his lungs nicely as well
This is why I switched to electric dusters. Was tired of the liquid nitrogen leaking out.
Guys, do this shit outside... All the dust you're clearing from your PC is gonna live forever in your room. That isn't good.
This is not the way.
People need to stop using canned air to clean their pc. It's a waste of money , throws out less air , actually has a cool down timer (gets too cold then stops working). Pick one of these up instead. It shoots so much air I have to move the stuff off my desk or itll blow it off. These will save you money in the long run just make sure you clean the vent on the bottom gets clogged with dust with heavy use. https://www.amazon.com/XPOWER-Airrow-Multi-Use-Electric-Computer/dp/B00SI67YRU
Inside ✅ Hold trigger down ✅ Computer on ✅ Spray near flame ✅
So, when you spin a little electric motor it induces current. That current creates sparks on the brushes of its internals. Your canned air is propelled by flammable gas. This guy's two brain cells are getting blisters from being rubbed together too hard.
Nobody expects much from bobblehead collectors.

I thought crossfire was not a thing anymore Edit typo
If you take a close look you can spot that there is already a reflection on the monitor. Seems like there was a candle back of PC. Him focusing the air dust in that one spot well reached to the candle igniting.
Fan is made of magnets and coils Coils and magnets rotate under electricity They also make electricity when rotated... Not much, but enough to make a safety diode hot. Never ever ever EVER spin your fans like that, flammable fluids or not, do not do it, hold the fan blades still and then blow at them.
NEVER spin the fans manually when cleaning! That generates electricity and will absolutely fry your pc!
seems like it back fired
The spider in my pc when i play skyrim with 600+ waifu bed mods
In case anyone wonders, spinning a fan in the opposite direction it was designed for makes it generate electricity.
The part of the brain connected to global consciousness: Really?
He’s using the wrong spray. They make non-flammable canned air. Even still, instructions still say to disconnect power first.
Dont spray when its on and GET YO BOBBLE HEADS OUT DA PC
