Sounds a bit like my Intel MBP, in particular after they (the company I work for) installed all the lovely bloatware/tracking crap IT thinks we need to be subjected to. Most of the day the machine runs with the fans blasting away.

Still doesn't take a minute to launch Outlook, but I understand your pain.

I keep hoping it will die, because it would be replaced with an M-series MBP and they are way, way, WAY faster than even the best Intel MBP.
