1 Copper

Alienware M17x R4 CPU Fan trying to cool GPU?

After my GPU kept over heating I spent a few weeks troubleshooting and I finally decided to take the back off my laptop and put it on its side. I noticed that as the GPU temp increases my CPU fan speeds up instead of the GPU fan. So in a programing sense Fan 0 which is supposed to be CPU is confused as Fan 1 and visa versa with Fan 1 which is supposed to be GPU. Is there a way to fix this?


I've tried to do it in bios but dell in their ultimate wisdom has locked out the fan controls and I haven't found a way to unlock the bios. I've also run the diagnostic tools from the boot options and the video fan test spins up the GPU fan. Then did the same thing with the CPU fan and the CPU fan spun up. But as I type this now I can feel the GPU is hot but the CPU fan is running almost maxed out but my CPU temps are just fine.


I have been able to slap a band-aid on this by using HWiNFO64 but I have to start it every time I start the laptop. It also will stop responding after a few hours and the only way to get it to close is to unplug the power adapter which 50% of the time causes the system to crash. Then it also will cause the system to take like an extra 2 minutes to shut down. I have wiped the system clean 3 times, installed every single driver, and even redid the bios all the way from the first release. None of this has worked. Dell also refuses to fix this as its out of warranty. (Honestly don't know why it should matter as its a dell caused issue and probably came out of the factory like this.) If i could just get into the software that's causing this issue and rewrite the fans I could fix this but that's above my knowledge.
