Hey all, Just built a new PC, and as it's been a while since I last did it I'm sure that there's a silly answer to this one. My problem is I don't have any control over the CPU_Fan on my P8Z68 Pro - it's running at 2000 rpm no matter what I do. I'm running a Corsair A70, and have both fans plugged into the CPU_Fan header via a 3 pin splitter. So far the following has had no effect: Changing the CPU_Fan profile in BIOS Changing the CPU_Fan profile in AI suite Using a User profile in AI suite Using Speedfan The mobo is running on v 0501 - I believe the most recent is 0606, is flashing the BIOS what I need to do? Was leaving this as last option as to be honest it scares me! Thanks in advance for any help.
