The heatsink alone is significantly cooler than the components, and the air coming from the heatsink even more so. A heatsink spreads that heat over a large surface area and blows air on that area. ![]() PC components heat up to temperatures like 50-80 degrees, that's quite normal. The airflow just moves the air around and most GPUs blow hot air all over the place Everything people think they know about airflow is a joke :) "Oh, I forgot the tape."įirst of all, in a case where you have airflow and an air cooled GPU, any theories about rising heat are absolutely irrelevant. It doesn't really matter much in terms of cooling ![]() some cases have dust filters all over so it wouldnt really matter but you'd be cleaning off the top filter a lot. I always do front intake only, through a dust filter. various youtubers have tested the temperature difference between mounting a radiator in front with the intake vs on top with the exhaust, and cpu temps are basically within margin of error.Įdit: if you have a blower style GPU and a PSU with the fan oriented upward so it's pulling air from the case, then there would be an argument for doing top intake as well. Yes the air will get warmed up a little by the gpu and whatnot before it goes through the radiator, this is also not a big deal. (you do want positive pressure inside your case, but only a little bit, which you will still have with 3 intake and 3 exhaust since 2 of the exhaust will be going through the rad.) positive pressure will build in your case and the fans will have to work harder. pushing more air in from above is just going to cause turbulent airflow especially with your GPU there too. you have fresh air coming in from the front. everyone saying 'heat rises' is just parroting this common idea but convection is negligible in an active cooling context, the air is far too busy being pushed through your case by the fans.Įxhausting out the top makes for far better airflow in your case, pun intended. So what do you guys think? Intake or exhaust for top radiator? Perhaps my brother may be right.Įdit: Wow! Wasn't expecting to get a reward for my Dickcheese PC Build of 2021! Thanks!Įxhaust is better, although your brother still doesn't know what he's talking about. Here is my well sketched diagram of my PC: The radiator is 240mm and I also have three front fans as intake as well as one exhaust fan in the back. But if I were to instead use it as an exhaust fan, I would be blowing hot air into my radiator which can increase the temperatures of my CPU. So anyways, I am fully aware that putting my top radiator as intake would blow hot air into my PC which could heat up my other components. "Dude you're fucking retarded, you're supposed to flip the fans and push air out of these case through the radiator instead because hot air rises, blah blah blah." I wasn't surprised, he was pretty much acts like that since he was born, and it's quite the norm. Apparently, this asshole scolded me instead and called me a retard for mounting the top radiator fans as intake. So right now I'm on my second PC build and showed my progress build to my brother so I could try to impress him.
