I opened up my laptop for the first time yesterday to clean out the fan, it was overheating. I had to take out the heat sink and fan in order to clean out the inside of the fan and I put it all back and made sure everything was connected. I turned it on, started playing a game on steam, but the framerate was incredibly unstable and went from 25-30 for a few seconds to 5-15 for a few seconds and back. Did I do something wrong inside the laptop? It's not overheating because HWmonitor shows temps of 50-70c.
