First of all, I would like to thank hmscott for bringing up a working fan speed controller for the G750 called NoteBook FanControl.
You can see his post on where to get it and how to use it on our G750 here:

Before I tried this program, my G750JX 770M temperature would reach 88C under max load. This was using the automatic fan controller.

So I installed NoteBook FanControl and set the fans to stick at 100%

Then I ran Unigine Heaven for ~25 minutes straight, and the temp would only reach 70C! (http://i.imgur.com/RyQ2CYI.gif) As I said, similar circumstances used to cause the GPU to reach 87-88 degrees.

That's nearly a 20 degree difference for me. Wow.
In addition, I was idling at just 31 degrees, (http://i.imgur.com/lXXOKlF.gif) compared to ~40 degrees.

This does make the fans very loud (at least by our standards) even at idle, but if you use headphones all the time, this may be a viable way to get your temps down by a lot.

Stay cool everyone :)

linear214, look at your GPU temps at idle with Notebook FanControl loaded and set on Auto. I found that the Notebook FanControl Asus Zenbook UX32LN Template Auto setting is incorrect for the G750, it left my GPU temp at 60c instead of the normal 42c.

If you want to live under Notebook Fan Control, please spend some time creating a new Template for the G750 that works correctly at Auto - otherwise you will be forced to adjust the Fan Speed manually all the time. Please post the working template you created back here and to the developer of Notebook FanControl, it would be very helpful :)

Leaving Auto on without a correct template may damage your GPU due to overheating. I have uninstalled Notebook FanControl until such time as a template with a working Auto setting is available.

Please be careful, and always watch your CPU/GPU temps while Notebook FanControl is installed :)

Hmm, you're right, thanks for the heads up. I only really use this to crank the fans to 100% permanently, but I can see why this would be an issue.

I set it to auto and it seemed to turn the fan off at ~59 for me. It would then cool down very slowly.

Then I went into the editor and saw that the threshold for the fan to step down to 14% is 65 degrees and turn off is 55 degrees, when the GPU is cooling down. Screenshot: http://i.imgur.com/9qzEgRl.png

These values are definitely not appropriate for the G750, so what do you think the values should be? It seems pretty easy to edit.

EDIT:I think the UX32LN GPU and CPU fans are swapped compared to G750
