Frequently Asked Questions

Does this work with all HDD’s?

Yes it does.

I replaced my Hard Drive in my iMac and I now have a loud noise like a fan, will HDD Fan Control Help

This is exactly what HDD Fan Control was created for, that noise is the HDD Fan turning at 6000rpm, it does this as it cannot determine your HDD Temperature. HDD Fan Control will read the drive's temperature and set the fan to an appropriate speed, and the noise will stop.

I have replaced my Hard Drive and after some time the Fan gets louder, but resetting fixes it for a while, do I need HDD Fan Control?

Yes, this is typical of the temperature sensor issue.

What temperature settings should I use?

The default settings are OK for most drives, but we would suggest checking your drive temperature range and setting the temperatures so that the fan would be spinning at 6000rpm before the drives max operating temperature.

Does this work with all SSD’s even those that do not provide temperature data over S.M.A.R.T?

Yes it does, HDD Fan Control will use the iMac’s calculated internal temperature to keep your drive cool and the fan quiet.

Does this fix the hardware test failure?

Unfortunately no it does not. The iMac still cannot read temperature signals from its temperature sensor so will still report this during the test.

Does HDD Fan Control work on a MacBook/Mac Mini

Unfortunately HDD Fan Control is only designed for the iMac, and it will not control the fans correctly on a MacBook or Mac Mini. We are investigating making it compatible with all Macs but because most other Macs only have fans to cool the entire system the control algorithm would have to take into account all sensors etc, and would effectively be taking over the cooling of the entire Mac.

Is the Windows version ready yet?

We are still hard at work developing the Windows version, and will be releasing a Beta version when we are confident it is working well enough to release for Beta. We do not currently have a time frame for this.

I purchased HDD Fan Control before version 2.0 and do not have a license, can I get one?

Since version 2.0 of HDD Fan Control we have required licensing. If you purchased before this, simply use the Contact Us form including as many details as possible about your order and we will create a license for you.

Can I remove HDD Fan Control from the Status Bar / Menu Bar?

HDD Fan Control is a system process that starts when Mac OS X loads and runs till shutdown. What you see in the status bar is a separate application called HDD Fan Control Monitor. It is only used to display current temperature and fan speed to the user and check for updates, this is not needed for HDD Fan Control to continue to work. To remove HDD Fan Control Monitor from the status bar and prevent it from re-launching when you next login simply click on the Temperature / Fan speed in the status bar, make sure "Launch at Login" is not checked then click Quit.
