I have changed my CPU-cooler with noctua NH-U12P. Since it have 3-pin connector instead of 4 I get an error message in BIOS which says there is no CPU-fan connected on the motherboard, which really bugs me. I have it all connected but not on the 4-pin which is suppose to be for the CPU-fan, which I also can't since I have a 3-pin connector on NH-U12P... I wonder how I can solve this problem <.<
