Hello all,
I have just purchased a new Z97 Extreme3 and fitted into a Corsair Carbide 540 case
The case has two frontal fans, they ARE NOT PWM (only 3 pins) and they are properly connected to
CHA_FAN2 and CHA_FAN3 (which are 3 pin fan connectors, again NO PWM, but I never had problem adjusting speeds on 3 pins connectors.)
No matter which FAN I try on CHA_FAN2, there is no way to adjust the fan speed.
Setting it silent in UEFI BIOS, or customizing fan level (1,2,3,4,5), or using FAN-tastic software doesn't help.
Seems that CHA_FAN2 has a set voltage and won't change it no matter what, and it's always at full speed.
Again I would like to stress that I've tried different fans (which work well and change their speed on CHA_FAN3) but the problem remains
Is this a hardware issue? Should I try to update the UEFI?
Also, in FAN-tastic tuning, "test fan" button seems to freeze on CHA_FAN2 for 2-3 minutes, and the listed RPMs are fixed (1010 RPM) for every %.
How comes I can change speed on cha_fan3 but not on cha_fan2?
many thanks in advance,
Ivan
