When not using my pc for cpu intentive tasks, I want the CPU-fan to turn off.
However the BIOS fan controls don't seem to support this.
I'd rather use the application SpeedFan to control fans, as this is much much easier to use, however I can't figure out how to let the BIOS set cpu fan control to manual (it's set to auto and is ghosted as readonly).
My questions are:
1) Is there a way to set cpu fan to manual, thus allowing SpeedFan to control it?
2) If not, is there a way to setup the bios fan controls to allow the cpu fan to turn off?
3) Is there a way to completely bypass all the fan controls in BIOS and let SpeedFan control everything?
4) When I set rear fan percentages, on which temperature limit does it react to?
I understand that you want to disable the fan control on the motherboard or be able to turn completely off the processor fan spin.
In regards to your question, I can confirm to you that the motherboard is designed to always send a signal to the processor fan so that it is spinning. You can lower the fan spin but it will never stop.
