Download AWCC update application, right click to Run as administrator, etc. and because AWCC already installed, a different window appears. Click on Repair, then Next, wait for repair successful window and then Restart to save the repair changes. When system boots, Open AWCC to activate repair. Hopefully, fan controls are reinstated. 
I've had my M17 R4 for about 4 months. I've loved it, but My issues with AWCC is getting quite annoying. The fan operation has been alittle screwy since I've had it. Fans will lock in at a low speed, or stop, causing the computer to overheat and freeze while making a fast clicking sound. I've got to hold the power button to shut it down. This will happen while gaming, browsing or even when it's idle and I'm out of the room. Upon restart the fans kick in at high speed till it cools down. I've tried different profiles, made my own, followed the procedures for doing a complete uninstall and reinstall of AWCC, AOC and the audio, registry editing, etc.Twice. It may work good for several days, then freeze 3 - 4 times in a day, then good for awhile. I can find no pattern to it. I'm now afraid to leave it unattended. If it freezes up while I'm not there, I'm afraid it'll damage itself, as it gets quite hot. Any suggestions on an alternate way to control the fans, without losing custom keyboard colors
