ASUS Z77 Motherboards - Official Support Thread

[toots]

Is there a way to get around the chassis fan speed restriction for the P8Z77-VPro? I can only lower it to 60% duty cycle which makes them super noisy at gentle load. Also the upper temp limit for chassis fan only starts at 40c which means the actual cpu diode core temp has to hit well over 60c before the chassis fan will ramp up.

I have it set up like this:

cpu header controlling mcp35x pump
chassis header controlling 3 1500rpm fans for radiator.
