Hello! I have noticed that on my DZ77RE-75K motherboard that the fan control does not seem to be working.
In the BIOS I have set the control temperature to 65C and the max fan duty cycle to 100%. But when the CPU temperatures go above 65C there is no change in fan speeds.
Another thing I am having a problem with is that the Intel Desktop Utilities Program does not seem to be working. When I start the program, a spinning Icon appears indefinitely.
All this is with the latest BIOS revision: 66
And I reinstalled the Intel Desktop Utilities application after the update.
Thanks for the help!!
Hey guys, since I never got a response from Intel, I started trying different things to fix the fan problem and I think I have found a way to fix it.
These steps worked great for me, now the fans are working fine.

It sounds like the BIOS configuration for fan speed control somehow got corrupted and restoring defaults fixed this corruption. This kind of corruption, in addition to affecting fan control, can cause Intel(R) Desktop Utilities (IDU) to get into this mode where the spinner appears seemingly forever.
If you get into this situation - and restoring defaults (and/or reinstalling IDU) - leaves the spinner spinning, send me a message. Attach to this message the following file:
on 32-bit Windows installs: "C:\Program Files\Intel\FSC\FSCAppServ.log"
on 64-bit Windows installs: "C:\Program Files (x86)\Intel\FSC\FSCAppServ.log"
I'm unable to save successfully options under the main menu>cooling tab the following options quiet/balanced/cool, basically the only one I can do is set minimum duty cicle under fan control, I'm still on 064 bios, all work perfectly but not colling options and control fan settings.
