This is the problem: chase's fan and power supply fan are always working on 1000 rpm.. Its not enough, so when i start a game, pc crashes: it freezes for about 2 minutes and than restarts.. Ive tryed to change the speed with sppedFan, but it does not any thing.
This problem come up when i bought a new motherboard, Asus p7p55 lx.
I also enabled speed control in bios, it still 100rpm.

Is the case fan actually connected to the motherboard or is it connected to the PSU with a Molex connector?

Have you installed all the drivers for the motherboard, perhaps there is a specific one for fan control??

Ok, your motherboard has something called ASUS EPU which controlls your fan speeds for energy saving purposes, try disabling this in your BIOS.
