There is an option in the BIOS under "PC Health Status" called "Fan speed controll method"

The options should be auto, Intel(R) QST, Legacy, and Disable.
Set it to disable to check if your fan is running good, and then set it to whichever you wish depending on what you feel is comfortable.
QST: Minimal noise, less speed, fan stays off a lot of the time
Legacy: The fan spins, but it depends on how the motherboard reads the temps
Disable: CPU fan runs at full speed

Now that I think about it, your fan probably isn't busted. But there's no harm in checking IMO.
