iMac HDD Fan Control controls your iMac's hard drives fan speed in relation to your drives temperature as reported through its S.M.A.R.T interface. Specifically designed for iMacs with HDD replacements and SSD Upgrades.

Have you replaced your iMac’s Hard Drive with a new HDD or a SSD and the fan has started running at full speed creating a lot of noise?
HDD Fan Control controls the fan speed in relation to the drive's temperature, slows the fan down preventing the loud noise and keeps your drive safe from overheating.

iMac HDD Fan Control does not require Apple’s temperature sensor or cable to obtain the drives temperature as it uses the S.M.A.R.T (Self-Monitoring, Analysis and Reporting Technology) protocol built into all drives, this means you no longer need the temperature sensor or cable for the fan to operate correctly.
