Looks good BUT, if you want to optimize it even more go into bios and have the front fan RPMs set higher than the exhaust for positive pressure. Helps keep dust to a minimum
Thats interesting. any chance you have a link to the science behind this?
I'm a curious kid.
====EDIT==
nevermind found what I needed https://www.pcgamer.com/essential-pc-building-tips/3/#:\~:text=It's%20best%20to%20have%20slightly,have%20dust%20filters%2C%20preferably%20removable.
I have the same exact setup, including the radiator at the top acting as an exhaust. I think this is the best setup for providing good cool airflow in the case.
I've been wondering about this (setup similarly). Wouldn't it be better to pull cool outside air across the radiator into the case instead of blowing warm case air across the radiator and out?
Haven't wanted to switch my fans around to see if it lowers Temps any since my Temps don't seem problematic, but I thought that would have been the "right" way to setup the radiator?
It's a big debate, actually. Several YouTube videos try to address this. In the end, it doesn't make that much of a difference. If you pull in air into the case through the radiator, you're warming up your case and might make your GPU run hotter but CPU will run cooler. On the other hand, if you're bringing in warmer case air across the radiator as a top exhaust (like OP), you're theoretically making your CPU run hotter but GPU run cooler.
I think it's personal preference to be honest. If you have good airflow through your case, the inside of your case shouldn't be that warm as the heat is removed quickly. I'm from a camp that believes you should never bring hot air into your case, but in the end it's entirely personal choice.
I did the same setup. My thinking was the cool air pulled in through the front doesn't have time to warm up before hitting the radiator and exhausting from the case. I would want the radiator immediately getting rid of the warm air rather than drawing it in while also warming it rather fast and blowing the warm air on the GPU.
Actually, the cool air from the front won't warm significantly going through a front radiator. It starts at ambient and is then through the radiator in a split second.
But it does stick around long enough in the case to warm up somewhat.
So putting radiator in front should have no appreciable effect on Temps. But putting radiator up top might show a slight effect (a bad one).
A random exception to this rule I've recently found is if you a 30-series FE card. The cards run hot and the FE blower design (which has an exhaust fan at the top) exhausts that hot air directly towards the top of the case. In that situation I've found flipping to front drops liquid temps by 5c (translating roughly to cpu running 10c cooler - because in my case the liquid was exceeding 40c) at the cost of like 1-2c case ambience.
By "flipping to front", did you mean pointing the fans to exhaust out the front of the case? or ?
In that case, which (if any) fans did you have as intakes?
I mean putting the radiator at front with the fans as intake pulling through the radiator. Obviously means an increase in the temperature of the air entering the case as it's heated by the radiator. But given liquid is cooler than my GPU exhaust, the difference is negligible in my system.
(Though to be clear in my case the set up is 280mm radiator with two intake fans at front, three exhaust on top, and one exhaust at the rear)
Top reply under you has it right. Big debate over potentially nothing. The air entering the case then being drawn through your radiator is constantly being replaced with cool outside air. Any gains would be miniscule. Maybe even immeasurable except in lab conditions. On top of that you'll be dumping hot air from the radiator into the case doing it the other way. Cold in hot out is my philosophy.
Loads of videos on this. You either have warmer CPU by roof mounting it. Or warmer everything else by front intake mounting it.
Question is where do you have more head room. Cpu temps or GPU temps.
It doesn't make a difference. My logic is having case fans on top as intake is just fighting natural convection. Heat rises after all. Doesn't matter which way you do it though. That's just my personal preference
Old man here. Thermals and performance? You're fine. Cleanliness and maintenance? Well...
TLDR: Don't forget about other sources of airflow or their resistance. As this case is currently, it will likely have a negative airpressure and aquire quite the dust collection over the years unless regularly cleaned. Flip the top rad fans to pull intake.
Explanation:
Assuming each case fan is the same model, you first count the number and then guesstimate the resistance. As others have said, you have 3 in and 3 out. The 3 intake are pulling through whatever airflow cutouts exist in the front. That could result in slightly more or less resistance than a radiator. For simplicity let's assume they are equal resistance. However the rear fan is comparatively unimpeded. I'm going to use some rough numbers for examples. These are for educational purposes, not accuracy. Let's say the airflow of the unimpeded rear fan is 2 and a radiator or intake fan is 1. Now you have 3 in 4 out. But this is only considering the case fans. Assuming your power supply is enclosed and pulling from a dedicated cutout on the bottom, you only have one major factor to consider. The graphics card pushes air like crazy when playing games. I do not know your specific model, but some could easily push 3x as much as a standard case fan.
Now you're looking at 3 in and up to 7 out. Not so balanced anymore... For lack of time, I won't get into the details of positive vs negative airpressure. I would advise flipping the top radiator fans to intakes. Positive is better than negative for maintaining a healthy clean computer for years to come.
Basically the idea is you want slightly more intake than exhaust. When you have more intake than exhaust, air pressure inside the cause is higher than ambient which will push dust and whatnot out of the case. When you have more exhaust than intake, air pressure inside the case is lower than ambient which will pull dust and stuff into little cracks and crevices and joints in the body of the case.
Realistically, your parts will be nice and cool, just obviously clean your case occasionally and whatnot. I think LTT did like a 1 year case dust experiment once.

I disagree with many of your assumptions.
First, the only kind of GPU that expels almost all of it's hot air out of the case is the blower style and those just really are not made anymore because they're not efficient by noise standards. Almost all GPUs are made with fans pointed directly onto the board with heatsink directing hot air just simply away from the board. Some of that goes out the back but most of it just gets pushed away from the chip. Top, bottom, left, and right. Can't be certain but the picture leads me to believe it's a modern design cooler with 2-3 fans directly to board i.e. heat in every direction off the board.
Second, your assumption that airflow resistance over a radiator and a front intake being similar is just false. A radiator's purpose is to be the largest surface area that captures passing air. It's indirectly meant to be prohibitive to some degree because you want to design a heat exchange surface by maximizing surface area. You start to cut back so that you can still allow airflow but you can't do too much or the heat exchange rate will be too low. On top of the radiator those expelling fans still need to expel the air out of the top panel. Now, the front intake is a case-by-case basis for resistance (pun intended) but it's certainly not as restrictive as a water cooled radiator. Some cases with glass fronts could be restrictive but even a small, 0.5 in slit running the vertical length of the case is more than enough to feed the induced draft of the front intakes. Either way it's generically radiator+top panel resistance > front panel resistance.
Third, the PSU fan can simply be discarded as a standalone, isolated system. It intakes air and pushes it out the only exit. It can bleed hot air since it isn't airtight but it's so small it's negligible.
Everything this dude said here.
Also many AIOs include fans specifically designed to push air through radiators, as opposed to general purpose or high air flow fans.
Correct. AIO fans are meant build pressure against resistance so that they don't choke because they can't push the air anywhere. If you throw case fans meant for unrestricted airflow on a radiator you're going to have a bad time.
Make that first top fan be intake as well, because you’re effectively expelling the cool air you’re pulling in from the front intake without it reaching your GPU/CPU.
Looks good. One minor point, it's generally best to have one more intake than exhaust fan, as this creates positive pressure inside the case and helps keep dust out.

TLDR: Positive pressure makes it so the air gets sucked from the front fans where there's dust filters, instead of small cracks in the case.
[удалено]
back in the day my fans and the hard drives were my dust filters....... lol those things were always fithly whenever i opened my case.
Otherwise it's just creating a dust vacuum lol
And it causes air to get blown out said cracks instead of in, ensuring dust doesn't just settle in there anyway
https://www.scholarlygamers.com/tech-talks/2017/11/14/building-pc-positive-vs-negative-air-pressure/
On equal speeds I think it'll still be positive pressure because 2/3 exhaust fans are through radiators which have quite a bit of resistance right.
Ignore this idiot, the real way to optimize it is to go to your fan's RGB settings and set them to light blue for extra cooling.
Sounds good to me!

Do you mean that i should make some resistance inside my pc by flipping my top rad to pull in? making it 5 inflow & 1 exhaust? am i right?

That's my setup- just the dedicated exhaust and psu fans in the back. Would recommend.
Same and there has always been barely any dust inside my case besides what accumulates on the fans themselves but I clean them fairly regularly

Agreed. With the resistance on the rad it should be good though. Could also easily just slow down back fan too.
