CPU & GPU temperature scary high

[FireFox]

Air that goes in == air that goes out. No matter the configuration, you can't defy the laws that govern air pressure. The only thing that you can influence is where most of that air goes out.

Yeap, but with exhaust fans the air takes less time to go out.

Let's stay on OP's topic, please.

OP has not responded, you're all literally talking to yourselves. Thread closed until OP shows up and asks for it to be opened again.

Sorry for the late response, I have read all of your answers. I added fan on the back of the case and Hyper 212 Evo on the CPU, it looks fine for now, CPU temp is around 50 °C while GPU is around 65 °C (while gaming), but i reckon it's normal. If you have time just write which CPU would be nice upgrade to my current configuration, I don't want to spend more than $250

Thanks!

i don't care how many positive vs negative air pressure gifs are used; there is NO WAY a vent will have the same air flow without a fan as with. well unless its a crappy fan . .but you know what i mean.

What moves more air ?

100 CFM fan => Building => Exhaust Vent
Intake Vent => Building => Exhaust Fan

Neither, the flow is exactly the same. Been practicing engineering for 42 years, additional info, boss (wifie) just said it's gonna cost ya $180 / hr.

Sounds like @vonKoga sorted his cooling very nicely, so apart from his wish for a new CPU, the rest is a bit moot now isn't it?

1 Rear (Exhaust) Fan = CPU: 64C | GPU: 85C
1 Top (Exhaust) Fan = CPU: 65C | GPU: 83C
1 Front (Intake) Fan = CPU: 67C | GPU: 80C

In the the single exhaust situation, the PC is receiving its intake air from, numerous sources ... pulling air thru the front intake fan location is the path of **highest resistance**.

When he adds the 2 exhaust fans, he has a negative pressure situation ... and where is the air coming in ? Thru the giant holes in the rear case grille ! ! ! . Where is the intake air coming from ? ... the GFX card and PSU exhaust. Duh it got hotter. Someone should suggest he do a test with a fog machine and see where the air is coming from. Best use of that case, 1 rear fan out, everything else in.

"Ummm top fans out and rear fans out ????? Next time use a fog machine and a big FAIL becomes immediately apparent. The negative pressure situation is sucking in outside air into the case from the case rear. What also in the way of air is at those giant case grille holes at the rear of the case especially when case sits on desk w/ rear against wall ? No thought to the exhaust from that 650 watt PSU or 300 watt GPU GPU ? Again, a $39 fog machine is a great tool to understand air flow. However another reality hit .... how many cases exhaust out into the middle of the room ? Are not most boxes on a desk with rear pushed against wall ? Since we got the fog machine, it's been much easier to demonstrate to our users which way to install fans. Thats why Corsair's instructions for their AIOs say "For best results, install fans with air blowing into the case".

Which scenario would be/work better:

2 x intake front + 2 x intake top + 1 x rear exhaust Vs 2 x intake front + 2 x Exhaust top + 1 x rear exhaust?

Heat rises, top intakes are never a good idea. I'd vote for 2 intake and either 1 top exhaust, 1 read exhaust OR 2 top exhaust and no rear exhaust.

So it would be cooler if I add 1 top exhaust?

if you already have a rear exhaust then no.

On my CM Storm Trooper I use two front intakes mounted near the bottom and one rear exhaust. The water radiator fans suck in from the top.
