High fan speed, slower processor, occasionally will not boot
I need help determining if my Air is worth repairing. Rather suddenly my Air’s fan began to run at full speed (this starts 3/4 of the way through the boot sequence), processing speed is slower-though not crawling (kernel_task is rarely above 5% CPU), and occasionally the computer will not boot-though I can’t consistently replicate this. I’ve tried SMC and NVRAM resets multiple times with no change and booted in safe mode and got a PFM006 fault. The computer repair guy says I need to replace the logic board, ~$300. Any suggestions on further troubleshooting or is this the likely cause? Thanks!
