So recently while gaming I've been getting FPS stutters. The FPS will go from playable (130 on games like League of Legends or 50 while on h1z1) down to 20 and then back up, constantly going back and forth. I posted on some forums and someone mentioned that it may be due to my GPU over heating. I decided that this is probably correct because whenever I restart my laptop the games play just fine, but only for a game or two (then the GPU gets hot again).
So I tried downloading a program called Speedfan, recommended in a forum archived on here from 2014, and discovered that the program does not detect any fan present in my laptop. To my surprise, when I put my hand where the fan should be blowing hot air from, I did not feel anything.
I have no idea why my fan is not working at all. Could this be drivers missing? Or is this a hardware issue?
I am grateful for any help anyone can provide for me. Thanks!
EDIT: BTW if it's of any use here are my specs:
Windows 10
Intel i5 5200u at 2.2
8 GB ram
Nvidia GeForce 940m with 2 GB ram
