    I assume it's not normal for a 17" 2011 MBP to be running at 95C while under 22% load. I'm thinking about taking it apart to reapply the thermal paste but wanted a second opinion.

    Clean it out if you haven't already, then go down the route of thermal paste. Usually a good air dusting does the trick on older machines, thermal paste can help but it's a little fiddly and high potential to mess something up; I'd only do as a last resort.

    I did take it apart and it's very clean, no visible dust in the heatsink fins. The fans also seem to be operating correctly, no weird sounds from them. I noticed the fan was running very often when I was just doing light tasks, so that's why I started looking into CPU usage and temperatures. Is there anything else to check before I go the thermal paste route?

    It’s clearly trying to boost abs it’s power consumption is rather high too. Are you sure there is nothing intensive running in the background?

    I checked and it's mostly just chrome or macos processes. 20% load is a little high, but I generally have 5 -10 tabs open and a few other applications.

    Have you changed the thermal paste on it before?
    If not I would try it out as 6-7 years is a long time for any paste and its effect on cooling should be worn out

    I’d recommend new thermal paste with those temps. Just changed mine on my 13” mid 2012 last week. Was idling at about 65 C (!) and throttling at 105 C when under load. Now idles at about 48 C (which still sounds a bit warm, but this is mostly due to the fan profile I think, it’s completely silent at idle) and hits about 91 C full load. Full load fan speed also dropped from 6000 rpm to about 4200 rpm so it’s much quieter now. Definitely worth it, just a bit fiddly to do.
