> 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.

Note: Runs as a 1 hour demo unless registered
