I'm a gamer and often play demanding games for extended periods. I currently have an i7 7700k and a 980ti, no OC for the cpu. I have a Cool Master Hyper 212 Evo cpu cooler, 3 vents, and 2 case fans. I'm worried about temperatures and my parts being heated to the point it does damage to their life span.
When idle, my cpu ususally sits at 35-45, it jumps sometimes to 45 but mostly sits high 30's. When under load of gaming, my cpu usually reaches about 70-74. Those are under more cpu intense games like pubg, gta v.
When idle, my gpu sits at 45 mostly. When under load of gaming, heavier gaming (pubg, gta v) the temps get up close to 80 celcius. It's the gpu that worries me as 80 seems high.
Though I am also worried of the cpu temps, I know the i7 7700k is known to run hot so I expected it but it was expensive, obviously I don't want it damaged. Anyway, some insight on this would be great
NOTE: My case isn't big, my wires are messy and there is dust but not a concerning amount I would say. I bought an air can though, going to clean what is in there off. So, be aware my case is a bit full. I also turn fans up in the 70% range when my gpu reaches 70 celcius.
Could you list your current system. Main thing I need to see is case and ram. Your right that PSU fan can't be controlled. Getting any current gen PSU from known manufacturer should fix that problem. Why you want to to be sub 500W though?
I would just remove that fan. If you have a case where intakes are in the front and outtake through the top of the case, making the fan an intake would just disrupt that flow, and making it an outtake would reduce the amount of air flowing through the radiator, which also wouldn't be any good.
So, to me personally, the fan doesn't really do anything at all, maybe even makes things worse. If you have all your top fans are intakes then maybe it makes some sense. Maybe I'm wrong.
