Fan spinning at 100% all the time
I’ve launched a game under Windows yesterday, but suddenly after a few seconds fan started spinning at 100%, then screen went black.
Post reboot everything is running as normal, temps are ok, performance is good, suspend/resume works, but fan keeps spinning at 100% (2600 rpm). I can still control it with Macs Fan Control.
I’ve tried NVRAM RAM reset and unplugging from the socket for a whole night, but doesn’t help.
Apple diagnostic shows PPN001 and PFM006 – issues with SMC and power management system.
Will replacing the bottom logic board fix the issue or I need to replace CPU board? Is there any way to force reset SMC?
