Macbook (16 inch 2021 M1 Max) runs very sluggish, fans always run at 100%, even on idle, and even in safe mode / recovery menu. The Apple diagnostic test returns nothing.
Activity Monitor shows no significant CPU usage (under 20%), kernel_task is < 10%
Memory Pressure & Disk Usage are low too.
iStats Menu shows efficiency cores close to 100%, performance cores barely being used. CPU seems underclocked at 1.8Ghz, 500mW
My suspicion is that the palm rest sensors are damaged somehow, because they show up as 0 in iStats Menu.
I also checked the MacsFanControl zip, and the smc_dump.txt confirms the same

I cleaned out the dust and sand stuck inside the trackpad assembly but it hasnt seemed to fix anything.
Any pointers on whether my intuition is correct, and if so, where exactly the palm rest sensors are located & whether I can disable them / ignore them would be very helpful.
