[QUOTE="pigoo3, post: 1890861, member: 56379"] Yes those temps are pretty darn high. Launch the app called "Activity Monitor" (usually in the "Applications > Utilities" folder). Click on the "CPU" tab (if it isn't selected already)...and take a look at the "%CPU" numbers. With the temps you're seeing...I'm going to guess you should see some pretty high numbers! One thing to try is booting into "Safe Mode"...this may eliminate any "rogue" items trying to run. A 2nd thing to try is boot the computer from a 2nd storage device (very likely an external HD with the macOS installed on it). Could also create a 2nd partition on your internal HD...install a fresh copy of the macOS on it...and boot into it. Since your iMac seems to be running ok since no other issues were mentioned (other than high temps & high fan speed)...I'm guessing something is up with the the macOS install. HTH, Nick p.s.
