Mac fan always running, even after SMC reset
Ive got a 2017 15" MBP with an i7 CPU running Big Sur.
The mac's fan has been running very loud for a few weeks now, i googled it and did an SMC reset, but this has not solved the issue. The fan issue happens pretty much at all times and all work loads.
Ive run the following terminal command sudo powermetrics and got the following result :
Any ideas ?
Think ive found the issue.
I took the back off the Laptop and the fans were full of dust.
Im not quite sure how they got so dusty, but cleaned them out using a can of air and the laptop fans are running much less now.
