CPU fan always at 100% - MSI mobo, AMD CPU

Question

The fan is always running at 100% (1800 RPM), even when the PC is idle (<5% usage) and temperatures are normal (<40C).

I've tried:

• Updated BIOS to latest version
• Installed AMD Overdrive, but the fan section is greyed out
• Set up fan profiles in SpeedFan but they have no effect (not sure if I did it correctly)
• Installed MSI Control Center, went to Green Power → Advanced → Mainboard, and set fan control down to 50% for CPU fan, but the speed goes back to 100% after reboot

Specs

• Mobo: MSI 760GM-P34
• Fan: Hyper 212 Evo (stock fan had same issue)
• CPU: AMD 4300

Answer 1

In BIOS, open H/W Monitor

1. Enable CPU Smart FAN Target
   • I set it to 50C, but I think any value will do
2. Set CPU Min FAN Speed to 0%
   • I suppose anything <50% will work
3. Set SYS FAN 1 Control to 50%
   • seems irrelevant, but I set it just in case
