CPU Fan header problem.

[Moothead2]

I'm having a problem where the fan plugged into the CPU Fan Header is always at 100%. I've tried both four pin and three pin fans (Thermalright and Arctic Cooling) so it's not just a fan problem. I've set it in the bios so that it runs at 50% until the CPU gets to 60 degrees but it continues to run at 100% even though the CPU is only at 30 degrees. I've also tried disabling the automatic fan speed and tried changing it manually using speedfan but the speed doesn't change. As a last resort I set the Bios settings to default and still nothing changes with regard to the CPU Fan speed. It was working fine a couple of days ago so I don't know why it's all of sudden started happening. What are the chances that the CPU fan header powers the fan but loses the ability to control the fan speed? My motherboard is a MSI GD53.

Thanks.

I always found it easier to use a fan speed controller, the only board I used which had good fan control was my Abit IP35 Pro with the uguru software.

I nicked my dads fan speed controller that came with the Xigmatek Midgard but I'm one fan header short if I take out the CPU fan header. I'm at that point though where I'm stuggling to justify spending even more money on this rig, especially as I plan to get a refund on my PSU (just generally loud so not quiet as advertised ) and spending about a tenner more on the Corsair HX650w.

Edit: D'you reckon one of those ones for a fiver from Hong Kong will do the job?
