2019 mac book pro overheating

Video clipping in quicklook overheats 2019 mac book pro.

After shutting down all aplications fan still running. I found in activity monitor quicklook was 102 % CPU. Forced quit and fans stop. I've been chasing this problem for a couple weeks, I have a large auxiliary fan that kept things running until I shut down, then restart seemed OK. Apple diagnostics found nothing. Today the fan was running 45 minutes after I was finished using Quick look with no applications running except activity monitor when I discovered the 102%.

? ? ? any clues, please.

MacBook Pro 15″, macOS 11.1

First, your Mac may be getting warm but it’s not overheating. If it does, you’ll know it because your Mac will shut itself off to protect the circuitry.

Second, each core can run at 100%, so under a heavy load (converting a batch of RAW images, for example) I’ve seen my 16-core Mac running at 1550% CPU.

If whatever software you’re using cannot multithread, you’ll see one core pegging and that turns on Intel’s Turbo Boost, which overclocks the core and automatically ramps up the fans.

You can disable Turbo Boost with a 3rd party utility like Turbo Boost Switcher. Most users report no noticeable drop in performance.

You have given me some peace of mind. I am a community college teacher teaching from home and have recently been experiencing some intermittent problems with slow screen sharing and network connections. We had a foot of snow last week, I was blaming the problems on my satellite connection, probably true. But have had a heightened sensitivity of how my Mac is running, the fan running really bothered me. It is my lifeline to employment for the past year because of the pandemic. I was afraid something was cascading to a crash.

THANK YOU
