For about a week my GPU fans have been spinning normally then dropping to 0 every few seconds. I'm not sure whats causing this because I cant seem to recreate the problem all the time, I will think I have the problem fixed then later that day or the next day it will begin happening again. I have take the GPU out taken it apart and cleaned it, looked over my whole PC and made sure the connections were secure, re-installed the RAM, Used DDU to wipe my drivers and reinstall new ones, and I uninstalled afterburner thinking it may have had a problem (don't believe it's the problem). Also when I have taken the GPU out sometimes and re-installed it the fans wont spin at all, so I unplug and re-pluggin the GPU cables and then it begins to work (even though the cables were definitely fully plugged in). I think it might be the cable extensions, However, I'm not really sure if that could be causing it to be so inconsistent with it sometimes working fine, doing the weird dropping to zero thing in the graph below, and sometimes not working at all.
