Why does my 2018 MBP run so hot all the time?
The area between my keyboard and the display hinge is too hot to touch even during "normal" operation. This is a 2018 MBP i9 32GB ram. All 6 CPU cores "idle" at 155F, same for the GPU. The fans don't think it is a big deal since they are cruising at less than 2500 rpm. Same thing with a test account. It ran a bit toasty at times before Catalina but seems to run at 155 all the time now but I cannot say it started with the Cat.
I know there is a bit of cruft left but I have removed old/un-needed StartupItems, LaunchAgents, and LaunchDaemons. I turned graphics auto-switch back on but I was running the dedicated GPU always before w/o a problem.
The photoanalysisd process chews up about the same CPU time as WindowServer but this puppy stays hot even when that drops back to 0% CPU usage.
I know I can ramp up the fans w/ iStat but would like to resolve the cause, not just deal with the symptom. A screenshot of the temps with only Mail running is attached.
Possibly unrelated but it has been crashing with CATERR panics often since the heat has been elevated. Coincidence???
Thanks for any suggestions,
Ran a few tests, these Macs really should be used for two things, either heavy workloads or extremely light ones. Using Chrome my dGPU was always active, adding about 15c to my overall heatsink temp. For what, there was no need for it, soon as I switched over to Safari it was fine, keyboard is cool. It runs great. My MBP shouldn't be running at 60c when just word processing with Spotify in the back and few webpages.
Switching over to Safari brought that down to 40c, which I'm very happy with.
It can be expected during heavy workloads that the CPU rises to high levels. That was expected without a doubt, I think it's the in-between loads when it becomes silly.
Chrome is just awful. Uses too much power for no reason, sure the MBP can handle it, but it's just daft.
