Hi guys,

I upgraded the stock ram in my Asus g751 as well as the wifi card but after the upgrade I noticed both the CPU and GPU fans were not running!

I put the original ram back and unplugged the wifi card but... Still the CPU and GPU fans did not run. They are both plugged in correctly and were never unplugged

Then... I replaced the CPU and GPU fans with original used fans on ebay and disconnected and reconnected the battery but...

They still both do not run!

I don't know what to do!!!

I believe the laptop warranty expired a while ago.

Is there a sensor in the laptop somewhere that is not working? The laptop boots into the OS fine but still the fans do not work even in a room with the heater on. I have not tired this for more than a couple of minutes at a time but I remember the fans used to come on when I turn the computer on.

Any ideas? Is there any software that can start my fans running for me?

have you tried booting into the bios boot menu to see if you can control the fans?
