Alright, so my problem is that when playing games, my processor hits 62+ degrees and it is only running at stock. I am using the asetek 570lx cooler with arctic mx-4 thermal paste. I tried reapplying the thermal paste but it didn't help at all.

Other specs:
Asus Crosshair V Formula Z
16gb ram
Radeon HD 7990
Evga supernova 850g2

Could there be something wrong with the cooler?

Start with more inflow air from the bottom. Too many fans can be almost as bad as too few, because you can cause turbulence and pockets of hot air. Remember cool from front/bottom to back/top ...

Have you tried with the side cover off you case? That would give you an indication if it is just insufficient cool air/exhaust from the case. If you have excessive heat build up in the case, no matter how good the heat sink is, it won't cool your CPU.

I am sure I didn't put too much thermal paste, and I will run prime95 with the case open to see.

UPDATE - is it normal for cpu speed to be at 3822mhz and 3248 mhz even though I already set it at 4000mhz through bios

Well I wasn't the one who put the pc together, but the radiator fans are facing down, I have a fan at the back, and two fans up front. Isn't there a default with how companies install fans (back fan is exhaust, etc...). And how do you check the radiator RPM? is it the same as the CPU rpm through HWinfo? If it is then it is 1473 RPM average

Oh and for reference, how do you know which fans are exhaust or intake?

Intake fans are sucking outside air into the case and exhaust fans are pulling hot air out of the case into the room. If you put your hand near the outside of the case near the radiator, is hot air blowing out or do you feel a cool breeze from the fans pulling room air?

So the prime95 test could very well show that the interior of the case is heating up too much from the graphics card and hot air doesn't allow the CPU heat to be dissipated.

I would run your games with the side off and see what happens.

You have a case airflow problem. Here is a guide to optimizing case airflow. Generally you want cool air from the front and bottom to move smoothly to the back and top. All fans in the back should be blowing to the outside of the case and the same with any fans on the top.

Alright, my 2 rad fans (up top) are exhaust, back fan is exhaust, 2 front fans are intake. Do I need 2 more intake fans at the bottom?

You have 3 fans PLUS the GPU trying to exhaust air. I might try unplugging the fan on the back of the chassis. The two top fans should exhaust enough to cool the voltage regulators.

You may need to look at getting better fans for the input air. Replace the existing ones with something with higher CFM. Or add some more.

What case do you have?

Cfi taiji full tower case. Also, temperatures seem to have dropped to >35 while playing... weird. I will still get 2 intake fans on the bottom. I have space for a fan up top as well, should it be intake or exhaust?

Alright thank you. Right now i am at 4.4ghz and temps haven't hit 40 degrees with case open, and will add 2 intake fans.
