PSA: clean your heatsink fins
My 2022 Legion 7 (3080 + Ryzen 9 5900HX) was getting scorching hot playing BF6 and throttling badly. CPU idling at 80C and instantly hitting 90C+ under load.
I repasted twice and thoroughly cleaned my fans. Nothing. I upped my RAM from 16 to 32GB. Nothing. I tried every possible setting combination for power, fans, and undervolting. Nothing!
Well, I tore it down one last time and blasted the shit out of the vapor chamber heatsink fins attached to the fan bodies with a fresh can of compressed air. I could see the dust shooting out of the fans.
Holy shit- temps are stable at no more than 75C under load playing BF6. No more throttling or FPS drops.
Sometimes it’s that simple!
