My 2010 Mac mini server fan speed 5xxx RPM is solved by swapping temp sensor soket between the 2 HD after a overheat shutdown problem and showed a exhaust reading error. Software fan control can help you diagnostic problem and temporary solved it by a fixed RPM, however it may damage your system while it is stopped to work and your system will be overheat w/o noticed fan is out of work. Also it would have occupied your CPU heavely, you should stop it(remove it from \Libary\App...) while you don't need it. Try to fix temp sensor first while you have a noise fan.
