MacFan For Windows Temperature Control in Bootcamp

This apps is simple and useful to control the speed of your fan in bootcamp. Apparently the fan control in Windows Bootcamp is not as good as in OSX.

2 apps to download:

  1. Core Temp - for temperature readings
  2. MacFan - to set the fan speed (run as admin in comand prompt)

Steps:
1. Extract the MacFan zip file.
2. Run cmd as admin
3. Navigate to MacFan directories in cmd (my MacFan folder located in Downloads folder)
Downloads\MacFan0_65\MacFan0_65\MacFan0_65\MacFan.exe
You can see the number of fan you have, and the minimum and maximum fan speed. In my case, I have 1 fan, min of 2000 rpm and, max of 6200 rpm.
1 fan, min=2000 rpm, max= 6200 rpm

4. Now we want to set our fan speed manually (press arrow up, for previous command), say 3000 rpm

Downloads\MacFan0_65\MacFan0_65\MacFan0_65\MacFan.exe 3000

Setting fan to 3000 rpm


That's all!

Remarks:

  1. Restarting your system will put the fan speed to default.
  2. At 3000 rpm my core temp was > 60 Celsius in idle. I reset the fan speed to 4000 rpm to keep the core temp below 60 Celsius (I run heavy image processing and simulation)
