HDD Fan Control controls fan speed in relation to drive temperature. If you have replaced your iMac's Hard Drive with a new Hard Drive or a SSD and the fan has started running at full speed creating a lot of noise, HDD Fan Control will control the fan speed, preventing the loud noise whilst keeping your drive safe.

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.

I purchased this app after trying out the demo. The demo seemed to work, but now my fan is back to full speed. I've tried adjusting settings in Preferences (btw i think that interface is well designed), but to no affect.

The menu-bar display says my fan should be at 1372 rpm, although the preferences target says it should be at 1100. I can hear my fan running very loud as before installing this software; much much faster than 1372.

Thanks for pointing out the price change, dufreyne. I've corrected the listing, as well as having updated it--slightly.

Macs Fan Control (available here on macupdate) resolves HDD replace issue for free. Plus adds a lot of more controlling features and works in Boot Camp.

$30 to fix a simple problem?

Vulture-ware.

Do yourself a favor and use a free fan controller.

Works OK, but no apparent way to find out which version you have installed. Neither the PrefPane when viewed in System Preferences or the PrefPane file itself when viewed in the Finder give you any clue what the version is. I have just installed v2.2 but I do not know if this is a different version than I already had installed or not.

Oh, and the Daemon file when viewed in the Finder also gives no clue what version it is.

Nick, this seems to have been corrected with the release of version 2.4, which we now have listed. :-)

Just replaced the Hard Drive in my iMac after it suddenly stopped working.

The next day the fan noise was crazy, I thought it was broken. A bit of googling and I realized it was this damn sensor issue.

I installed this and the noise stopped near instantly!!! An instant purchase!

The price is well worth it to stop that awful noise, and I now know the fan is working correctly again.

I did check the settings as I wanted to make sure that the drive would not be overheating and found that the defaults okay for my drive, but a bit of adjustment and I am very happy, the fan hardly ever increases in speed and only seems to do it when the drive is in heavy use. I tested this by copying very large movie files for an hour.

Thank you Surtees very much for the great fix.

I learned of your Fan Control software after looking on here [MacUpdate] for fixes for my iMacs fan problem. I replaced my hard drive several months ago, and didn't discover a good resolution until yesterday--I downloaded the trial, it performed as promised (the fan slowed down straight away!), so I purchased the software and it works marvellously! Thanks you.

Had to replace the drive in a late-2009 iMac (Lion OS) with a consumer – i.e. unformatted – version of the original drive. Hadn't gotten below 6000 rpm for a week, despite trying smcfancontrol etc. This is the ONLY software that went directly to the source of the problem – the loopy drive temp control system in that generation of iMacs – and fixed it. The fans slowed to about 1200 rpm the moment it was installed. (Right now, the HD is at about 52C and 1863 rpm while a full system backup is running.) Yes, $30 is steep, but it's a small price to pay to expel that hideous fan roar from an iMac. If that sound is making you nuts, this app won't disappoint. And you can demo it for an hour first!

Since upgrading to 10.7.3 it doesn't seem as if HDD FanControl is functioning correctly. I have mine set to a minimum fan speed of 1000rpm and set to increase from 50degC, but even with the current cpu temperature at 22degC the fan is running at 1267 rpm.

It looks to me as if HDDFC is not actually controlling the fan temperature any more so the question now is what is actually controlling it? Before installing HDDFC the fans ran at full speed but they are not doing that now, so something is limiting the fan speed.

As a follow up to the above, cpu temperature has now risen to 40degC but the fan speed is still 1267 rpm. It may be that there has been a tweak to the interface to the fan control that means that when HDDFC sets the speed to 1000rpm it actually ends up being set to a higher speed.

When I change the settings so that the speed should be higher (by moving the start of the ramp down), the fan does speed up, although it doesn't get to the target speed. I wonder if a ratio has been changed in the OS?

Hi Nick, thanks for your comments, HDD Fan Control should work fine in 10.7.3.
I have sent you a message to the email address you provided with your order so we can look at what may be causing your fan to run faster at its minimum.

Thanks

An update on my experiences.

Firstly, must say that Ben was as helpful as he could be and provided a list of possible causes all of which I explored. Ultimately, however, my system continues to perform differently than it is set to do in HDDFC.

The minimum speed never drops below around 1270 rpm, even when it should be 1000 rpm. Also when it speeds up it never quite gets to the target speed.

I am however not overly concerned about this as the fan speed does vary with system temperature in a reasonably sensible fashion, even if it doesn't quite follow the rules!

I can't imagine what is causing this issue, but one very positive thing is that I had no problems at all when upgrading to ML.

Pripyat had trouble on 26 Mar 2012
Doesn't work correctly on my late 2009 MacBook Pro running Mac OS X 10.7.3. Shows current speed as -1RPM and tells me that my CPU's temperature is 35C, even though iStatMenu tells me it's 62C.

This app seems to be kinda disconnected from reality. :P
