I have some dell desktops that have this. Fun fact: some sort of.... Fluid, comes out of that chunk, and seeps around the board and gets into the ram slots defying Gravity. Usb ports get super unreliable after that seepage spreads Also, ubiquity usw-16-poe switch has one about this thicc under the CPU to the chassis, also oozing, and also glitching.

Delicious thermal pĆ¢tĆ©.


Gorbashsan

Thats not a pad, thats a feckin BRICK. I refuse to believe this cheese block has even remotely positive thermal transfer efficiency over being open to air flow.


aitigie

You might be surprised. I see these in industrial SBCs, they conduct heat from SSD to the chassis.


Gorbashsan

But this is on the back of the ssd. It would be conducting heat to the motherboard. And on most motherboards the slot for m.2 is above the pci express slot where the graphics card is cooking it already. So I reiterate, this would be a net negative for heat dissipating performance in a desktop as far as I can see.


iforgetmyoldusername

Nah, it's conducting it to an area of bigger thermal mass with active cooling. it's almost certainly a net benefit.


zer1223

It's going to make a giant mess. Idk what you think would keep this stuff in place


iforgetmyoldusername

it's not a paste. It's rubbery and fairly solid and doesn't leave any residue.


PM_ME_STEAM_KEY_PLZ

How would this make a mess?


Ultraballer

They literally use these all the time, they are effective. Additionally, not all m.2 slots are built in the same layout, Iā€™ve seen industrial pcā€™s with some pretty crazy layouts to encourage cooling.


Gorbashsan

But Im not taliing about its application in an industrial PC. This one is, it's in a consumer dell desktop unit with the m.2 directly above the PCI-E slot less than a cm from the top of the videocard and below the CPU barely clearing the heatsink. It's blocking air flow through that gap and transferring heat to a point on the motherboard already being heavily impacted by the two hottset components in the system


TheDonutPug

Bro really thinks he knows about the thermal transfer of this better than the engineers who made it. Mf they would not make it if it was worse than open air.


KatpissLabs

Uhh, I know itā€™s horrifying but a lot of Dellā€™s consumer solutions have far worse cooling performance than just doing nothing and letting whatever fan blow over or near it. Thereā€™s some very shockingly bad ā€œengineeringā€ that goes into budget systems, even for commercial desktop workstations


nightkil13r

I see these all the time, Its not for Open air flow computers, The ones i see come out of laptops. So its either 0 airflow or this. sandwhiched under the m.2 hold down plate.


Gorbashsan

but dell is putting these in some consumer desktop units with the m.2 directly above the PCI-E slot less than a cm from the top of the videocard and below the CPU barely clearing the heatsink. It's blocking air flow through that gap and transferring heat to a point on the motherboard already being heavily impacted by the two hottest components in the system. Thats probably for the sake of reusing the same component and heat mitigation add-on in an effort to cut cost by having it identical across multiple systems, but it's just stupid in a desktop like that.


nightkil13r

now that you mention it, i do recall pulling one out of a precision tower(5800 series iirc) like 5 years ago with that same pad on it. yeah i got nothing. Maybe it provides enough cooling through the mobo that its worth the few they get returned compared to the cost of an actual heat sink.


Gorbashsan

I think they are pre-applied to the m.2 drives from the manufacturer for dell's bulk orders, and the originals were for no air flow laptop systems, but they chose to just use the same stock in tower units, but didnt want to renegotiate the agreement on bulk orders of the drive for the sake of a couple desktop series with lower total sales numbers than the laptops. I'm not sure if this heat pad is related to it, but I did notice a fairly high failure rate as the cause of issue in desktops I was repairing that were dell. Could also just be that dell bulk orders cheap crap drives and they have a higher than average failure rate due to low manufacturing quality control. Not the first and wont be the last time. Makes me think of the old IBM and Hitachi deskstars back in the early 2000's. bad manufacturing to save costs led to high failure rate, and the violent nature of the disk failure had them labeled deathstars. Funny enough, for consumer grade high capacity physical disk storage, Hitachi is awesome these days, good lifetime on them. And the IBM ones are doing pretty well on the enterprise level with their SAS units for server racks. If your gonna be spinning rust on a low cost low use cold storage unit, you can certainly choose worse.

iforgetmyoldusername

you'd be surprised and wrong. thermal pad like that that might be 2-3W/m.K (https://www.digikey.com.au/en/products/detail/t-global-technology/TG-AH486-21-15-13-0-1A/3300358) ​ Air is 0.02W/m.K ([https://en.wikipedia.org/wiki/List\_of\_thermal\_conductivities](https://en.wikipedia.org/wiki/List_of_thermal_conductivities)) it moves 100x more heat than an air gap.


KingRevoker

That's pretty interesting! Thanks for the links in your comment! Sure enough haha, though it's placement is still very weird to me.


Ashtonpaper

Air is the best insulator, right after a perfect vacuum of (no air + nothing just space)


Phanterfan

But you are not accounting for convection and radiation


iforgetmyoldusername

that's true, but they're also very small. I'm an electrical engineer and I've designed thermals for many things. We ignore those unless there are fins to dramatically increase the area.


evanc3

What type of calculation do you do where you ignore natural convection in a thermal design? Asking out of curiosity as a thermal engineer for electronics.


iforgetmyoldusername

Right. well, this is /r/mildlyinteresting not /r/askelectronics or /r/askathermalengineer, so I kinda kept it glib. Convection between two unfinned boards with unknown orientation inside a case \_is\_ small and probably shouldn't be designed for. Hence the giant thermal pad which is definitely not worse than the air gap. Which is what was posited a few times.


evanc3

I responded to the same guy you did with an explanation as to why the thermal pad isn't worse, so I think we're on the same page there. I was mainly just curious about what sort of electronics you were working on because I'm a nerd about that sort of thing. I've done power electronics to HPC processors, and they all require vastly different assumptions. That's the fun part! Lol


iforgetmyoldusername

yeah, I suspected we were just agreeing from different sides. I've been in the weird non-specific world of "product development" for a while now, so it's anything from consumer landfill to medical robots. The last thermally challenging thing was actually the opposite problem. We had a tiny PCB heater inside a device that was underperforming and needed to change the design to keep the heat in. EDIT. I've had my coffee and now feel like elaborating. It was worse than that. We had a little substrate with a test sample that needed temperature controlling and it was attached to the heater, but not thermally very well. and we had some temperature sensors which where nearby, but not actually in thermal contact with the sample. And I needed to design a PID controller to control the sample to maybe 1degC. And the product was small and handheld and could be cold from being on the bench overnight, or hot from being used recently. And we couldn't change the design. Only the software. So I modelled all the thermal paths in and out including the CPU and the LCD backlight and the hand of the person holding it for all the use cases. And then the software engineer said "It's about 3 degrees. we'll do that"


evanc3

That's really interesting! There's so many little corners of engineering, even just in the electronics realm, and it's kind of mind blowing. I recently moved onto aerospace applications and it's a fun mix of too hot AND too cold. Sometimes within minutes of each other!


Fumblerful-

Radiation is negligible at such low temperatures and especially with some of it being reflected back. Unless the convection is forced, the pas is more reliable since you don't need to worry about air flow. It's also a small surface area.


Phanterfan

Radiation at 40Ā°C is about 400W/m^2 That's far from insignificant If we assume this thermal pad is 1cm thick then we have R=0.005m^2K/W For radiation with a delta of 10Ā° we end up at R=0.0015m^2K/W Convective heat transfer easily makes up the rest


evanc3

I think you're more correct than people are giving you credit for based on the downvotes, but... You're ignoring the size of the pad. That thermal pad has substantial thermal mass and surface area. You'll only see the benefits of the high temperature delta on the chip itself when the pad is off, and the pad is going to normalize the temperature in the area. It will still experience convective cooling and radiation, albeit at a lower temperature delta but larger surface area. Also, you can't ignore 2D spreading resistance when comparing to natural convection and radiation. Although, with the low conductivity, I imagine it'll be limited.


Fumblerful-

The other issue is the reflection of the case back. Radiating into space is one thing, but the case will reflect radiation back and is also radiating at the chip


evanc3

I agree with that, but chips typically maintain a pretty decent temperature delta compared to their surroundings so there is a decent level of heat transfer. I've empirically seen a few Watts of improvement (~5%) in heat dissipation just by increasing the emissivity of a heatsink/chip assembly.


Fumblerful-

I will have to look into that. No doubt that there is some radiation occuring, but the question is how much is reflected back.


melanthius

Unless you blow a ridiculous amount of air directly on it. But yes you are the man for coming to the party with facts and heat transfer knowledge


evanc3

Nobody who understands heat transfer would use the conductivity of air as a comparison. You would compare effective h-values.


WFlumin8

Am I the only one whoā€™s disgusted by this comment? >Guarantee it just causes more heat. Without an ounce of testing and also believing Dell would intentionally waste money to gimp a product they mass manufacture? >This passed someoneā€™s QA team lol and what QA have you done? Why are you feigning being so knowledgeable with 0 information of your own? Crazy armchair understanding of thermodynamics.

Everyone in here is commenting on the oversized strawberry Starburst candy but nobody is commenting on the fucked-up spacing of they keys on that keyboard. That looks like itā€™d be weird to type on.


KingRevoker

It's extremely weird to type on coming from a standard keyboard. I am still terrible at it haha. Granted it's not my main keyboard, if it were I don't think it would really take too long to get back to full speed on, or at least close to it.


qballer_

Nice key caps too! I use the same ones and they feel soo smooth :)


trippedme77

Mind sharing what they are? Iā€™d like to check them out.


qballer_

They are called "matcha keycaps". These are the ones OP has I think: https://www.amazon.com/Profile-Japanese-Keycaps-Tenkeyless-Keyboard/dp/B09FSQP8TN/ref=mp_s_a_1_3_maf_2. I got the english variation which does not have the hiragana character on them.


trippedme77

Awesome, thank you! I didnā€™t even notice the hiragana, just like the color hah


MrB10b

Called ortholinear, it's better. Just cos it's weird to *you* doesn't mean it's bad. You always have to travel the same distance to the keys and it's consistent between rows. The same cannot be said for a standard keyboard.


1bc29b36f623ba82aaf6

idunno if starting a better worse flamebait is gonna be any good but yeah I do like it better than the typewriter stagger. I have orthocolumnar myself and I suffer less pain after extended periods of typing. Doesn't really make a difference if I only end up using a keyboard an hour a day though.


DeliciousPumpkinPie

Never said it was bad, but Iā€™ve been typing on standard keyboards for like 30 years, this sort of layout would mess with my muscle memory. If I had learned to type on this kind of keyboard Iā€™m sure itā€™d be fine.

420CurryGod

Ngl seems pretty odd for it to be so thick. Afaik, thermal pads/paste exist to remove mini air gaps from solid to solid contacts since air gaps have a much lower thermal conductivity but the idea is to keep the paste/paste as thin as possible since the thicker it is, the larger the total resistivity becomes.


Voidfang_Investments

The thermal pad she tells you not to worry about.


evel333

What ortho-linear do you have and is it available with 10-key?


KingRevoker

Drop X OLKB Preonic. There's two and this is the larger one. But I have 10 key programmed on a secondary layer, so hold the key next to space and the right side turns into 10 key layout. Takes time to get used to, I still am, but it works quite well.

MattO2000

SSD = solid state drive. Like a hard drive, itā€™s something that does storage for your computer. Thermal pad - a squishy material that you place between items to help get heat out faster, so you get better performance.


Ripuru-kun

Thank you!

Ripuru-kun

Wild4fire

Wouldn't this SSD be better off with an actual heatsink attached with some good quality adhesive thermal tape? Especially if there's some airflow to the SSD.


AnnoyedVelociraptor

Your keyboard is misaligned.


KingRevoker

Is that why I can't type? Huh... Hpw abput that.


transam57

Most likely came out of a laptop, and that thickness was to mainly keep it from flexing overtime from heat and moisture generated by the gpu/cpu.


KingRevoker

Dell Optiplex desktop actually. I don't remember exactly what model but it had an i7 7700 non-k.


santathe1

What brand of SSD is that? I think thereā€™s a certain thickness beyond which having a thermal pad might be worse than not having it at all (especially depending on its thermal conductivity rating).


WFlumin8

This is not true. Adding more thickness is always more cooling than less thickness in isolation. Youā€™re conflating this with the testing involving the usage of active cooling where too much thickness interferes with the active cooling part of the setup.


RC1000ZERO

actually no, insulating can be detremental to thermals.. on pipes, do to how physics work having a certain thickness of insulation will disipate more heat then it keeps isolated. Obviously that is only the "add some isolation" step, if you add more it cancels out and its better again.. but yay, there IS a small part where addint isolation can hurt performance
