My machine has the same problem: 1. clean the heatsink 2. add some heatsink foam (blue) 3. remove the display cable bracket After that, I feel good under 40 degrees, the screen also stops shaking

P1: P2: me too I used Temp Monitor and found that the sensor was faulty (P1) Use everything like SMC, remove the battery ... as ineffective. I removed the heat sink to clean it, then carefully reinstalled it, everything works normally as shown in the attached picture P2
