NOTE: This app is specifically designed to control your HDD Fan using your drives S.M.A.R.T data for iMacs with replacement drives which no longer provide correct temperature data to Apple's sensor.
HDD Fan Control will run the fan at the correct speed, and keep your drive cool and safe from overheating. If you are looking for an application to adjust your Mac's fans from stock (and not to control fan noise after replacement disk) we can highly recommend the free smcFanControl or iStat Menus
- Added support for OS X 10.10 Yosemite
