So i recently built a new gaming rig and i have some issues with the CPU temps:
@Stock clock speed/Voltage:
Idle: 40ºC
Playing Arma 2: 63-69ºC
AIDA64 Stress Test: 68-70ºC

@4.3Ghz/1.230V
Idle:45ºC
Playing Arma 2: 76-80ºC
AIDA 64 Stress Test: 76ºC with peaks of 80+

Today after seeing this, i reapplied thermal paste and almost got no change.
The case is the NZXT s340 with the included fans as intake in the front, the radiator as exhaust in pull position at the back, and another fan as exhaust at the top, all 120mm.
Also gotta mention that, when i was replacing the CPU(the old one was an i5-4590) i bent some pins in the motherboard socket, so i had to straighten them back(it worked).
 
Solution
If the system is working, I doubt the bend pins are a problem after fixing.

Your temps aren't horrible. You might do better with your temps by forcing fresh air into the radiator (push to rad) rather than drawing it and having your top exhaust fan to discharge warm air out of the case (hot air rises). Also be sure your pump is connected to an always-full-RPM header. And that the radiator fan is connected to the CPU FAN header.

I already put the radiator fan in push position and got better results, like 5ºC cooler. The pump is conected to cpu-fan header and the radiator fan is connected to a regular sys-fan header(i think that's the way it goes).
Any more ideas? A lot of people are telling me that my temps with my current setup shouldn't be that high...

The rad fan is supposed to be connected to the CPU FAN header, not the pump. That way the rad fan can speed up or slow down like any other cooler fan. That's why it is a PWM 4-pin fan.

The pump should always run at full RPM. So be sure there its header isn't set to some kind of AUTO setting in BIOS.
