Cleaned yes, re-pasted no.
Funnily enough I've just booted a game up without the charger plugged in and the vibration/fan doesn't seem to be an issue.... wonder if it’s power related.
TLDR:
- Have had this laptop for ~4 years with no issues. (No Warranty)
- Last week one of the fans (left side) decides to make a constant loud noise whilst the keyboard vibrating like an electric toothbrush.
- Only happens when a game or a browser with a video is open/playing
- Contacted PCS...
