Hello. After reapplying thermal paste to my CPU, the CPU's fan now spins at its max speed at all times, no matter how hot the CPU really is. On boot, I get the CPU Fan error, and have to press F2 to even boot my computer. I've checked around in the BIOS and could not find any options that were even close to any sort of fan control. I've tried Speedfan as that seems to be the only program I can find, and after looking up many tutorials I've only been able to fully control the chassis fan on my computer. This isn't a necessity, but it would really help if anyone could help me solve my problem. I've included my system specs below.

OS: Windows 7 Home Premium 64-bit SP1
Bios: American Megatrends 5.04 dated 10/1/2009
CPU: AMD Phenom II X4 910 Deneb 45nm Technology
Motherboard: FOXCONN ALOE (CPU 1)

Please, if there's any more information that you need to help fix my problem, please reply below. Thanks for your time.

Read through the mobo manual. I don't even know if the Foxconn mobo has uefi

Well then if you can't do anything in bios either perhaps you need to think about getting another motherboard.

You can add a resistor lead to the fan to slow it down -

The only problem is noise, and I'd rather buy a new computer than upgrade the motherboard on my current, but hopefully there is another way to slow it down.

Use that or similar resistor.
