I had to replace my battery on my 2 year old alienware 15 r2, and now that everything is put back together and working, the GPU fan (left side fan) runs at a constant low speed and no longer adjusts to the needs of the computer. Before the battery change all was fine. The company I had work on my battery I'm having check to make sure nothing is wrong physically with the fan. Any suggestions on what would fix this issue?
Are you running the latest system Bios version? If it happened right after the battery was replaced, it could be a hardware problem with the fan, perhaps it was not installed properly.
