Fan spinning at 100% all the time

crwdns2934249:0crwdne2934249:0:

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?
