Laptop's Fan is running at full speed since windows 10 update
Hello every one,
I also had the same problem. After updating my Windows 8 to Windows 8.1 and later to Windows 10, the fan started to work at full speed with lots of noise. I tried many different methods that didn't work. Finally I found the following solution.
Basically, the problem is that your graphic card drivers are not compatible with your motherboard. You need to install an older version of drivers which is compatible with your system, not the latest ones!!!
In order to do that:
1. Make sure you cancel the automatic update. Go to device installation settings and check ?Never install driver software from windows update?
2. Reboot
3. Uninstall all graphic cards from device manager
4. Reboot again
5. Go to device manager and make sure your system did not automatically install the graphic cards.
6. Then, install an older version of graphic card driver which is compatible with your motherboard. For my laptop (SONY VIO, bought in 2013) after a few trial and error, I found this version completely compatible with my system: AMD Radeon HD series version 15.301.1901.0. and INTEL ? HD graphics 4000 version 10.18.10.4226. (It is about a month that my system is working without noise).
7. You may also needed to update the motherboard cheapest drivers too.
Interestingly, this remedy worked for my internet wifi too. After updating my Windows, my laptop used to disconnect every half an hour or so.
I installed an older version of driver (Intel Centrino (R) wireless N 2230: version 15.12.0.6) and it got fixed.
Hope this solution works for your computer too.
