Ailing MBP, help needed.

Hey Mac peeps of Micro.Blog, I need some help.

The fan on my 2017 13” MBP comes on full tilt every 20 minutes or so, even when I’m just reading, surfing or drafting in Bear. Nothing processor intensive. In fact, it rarely even feels hot to the touch.

I’ve backed it up, wiped and reloaded Catalina several times, done a PRAM reset, and have scoured the internets for answers. All to no avail.

So I decided it was time to hit up this community in an effort to NOT have to replace an otherwise perfectly good laptop, no matter how much I despise the keyboard, just to make the fan STFU.

Any further thoughts, ideas, suggestions, or nuggets of wisdom?

Any and all input will be gratefully accepted.

Thanks.
