Asus p7p55lx fan speed problem

[Oleg Derezzed]

My chasis fan runs always at 1000 rpm and its too low cause my system overheat.
But i just cant change the speed. In bios there's no option for changing speed, only Q-fan, but its not working and fan steel at 1000 Rpm.
Neither speedFan cant control my chasis fan.

If the fan is connected to the motherbd for power you can try connecting them to the PSU where it will run at its max speed. A few chasis fans have a speed controller hanging off them, like a small switch. If yours doesnt then you will need to order replacement higher speed fans.

Is there some chance to increase the speed through software?
