HDD Fan Control works to fix this issue by reading the drives internal temperature using the S.M.A.R.T protocol and set the fans actual speed to a value good to protect the drive.

Instead of HDDFan Control, get the free SSDFan Control

By using Fan Control, the users of Mac OS X operating systems can get and instant access to the. It runs at startup and continually to always control the fan correctly, prevent the loud fan noise and protect the drive from overheating Fan Control is a free and hassle-free fan speed manager for Mac.
These programs will not work for this particular issue as they often only control the base speed, and if they do control the fans actual speed they rely on the temperature reported by the sensor which is now incorrect.

If you replace your drive, your iMac will initially seem fine, but soon the fan will begin to speed up to full speed. This is due to Apple replacing the external Hard Drive temperature sensor with a proprietary firmware and using the drives internal sensor. Replacement drives do not contain the firmware to deliver temperature data on the temperature sensor cable. When the iMac does not receive a good signal from the hard drive it puts the fan at full speed to protect the drive. Since the late 2009 iMacs came out, replacing the hard drive has caused the internal Hard Drive Fan to start running at around 6000RPM. It's because of the drive replacement.Hi, likely the new Drive doesn't have the Termal sensor. But that's for another thread.īut you can't run smcFan and SSDFan concurrently.Īnd this has nothing to do with resetting the SMC. I have been running smcFan on this Mac for three years plus, with no problems because I know how not to overdo it. HDDFan Control is not cheap, However, there is a FREE version of HDDFan Control, which should do the job.Īnd by the way, smcFan Control, used for the purpose of manually regulating the fan speeds to minimum speeds- it's only purpose-where they would not be ramped up properly according to temperature, will NOT prematurely burn out the fan motors, so long as you keep the pre-sets within reason. In other words, it will keep the fan revs where they should be. You DO want HDD Fan Control, which will keep the drive fan regulated according to the input it is receiving from the System Management Controller (the SMC), and prevent the drive fan from ramping up to maximum rpms in this situation. This free app is much better and powerful than HDD Fan Control, which is currently deprecated but still costs 35. The coolest thing that it can also set a fan to sensor-based control depending on your new HDD by reading its S.M.A.R.T. That will only allow you to set minimum fan speeds in different presets. Macs Fan Control can set the fan of an iMac (or MacBook, or other hardware) to any speed. You don't want smcFan Control for this job. A lot of misinformation has preceded my post.
