Also, are the fans you're using 3-pin or 4-pin PWM? Are they plugged into the motherboard headers, or are they powered directly by your power supply via 4-pin molex?
Have you tried software like Speedfan to control the RPMs of your fans?
The CPU fan is the hyper 212+ is 4 pin and the exhausting case fan is 3 pin.
After install speedfan and use auto fan speed, the 212 drop from 1800 to 800. much quiet.
But the exhausting fan is still at 1500 rpm.
Anyway to quiet it down?
