Hello, this new board seems to limit my 2x3000rpm intel stock coolers speed. One comes from a Intel 3220 and worked fine up to 3000rpm, and the new one is from this new Intel 4460 that i've ordered for this board.
They are able to reach 3000rpm in another system, but not in my H97M Pro4 - bios 1.20.
Both coolers are connected through 4 pin layouts on the mobo, one for CPU1 and the other for Chassis1. I've also tested 3 pin layouts but it's the same.
Both were manually set to 100% in UEFI and in A-tuning utility in Windows 8.1 and Windows 7. Settings are to reach 100% fan speed starting with 30C.
They never go above 2100 rpm and power settings are set to Active.
Other than this, PWM function in defaul settings works fine up to 2000rpm,but little air is moved.
More important testing: both coolers were tested and input 12v power on the yellow wire. I've swapped even a different power supply and tested yellow+black straight connected to a molex cable and the other 2 connected to the motherboard. Same thing.
What i need to mention, is that the Intel 3220 stock cooler starts spinning 3000rpm for 2 seconds on PowerON. That's the dust cleaning feature and tells me 12 volt input definitely works.
Also Asrock A-Tuning utility reports fans running at 12v, so hardware problems.
This is definitely a bios bug, please report to devs.
