I have a mac mini (previous gen) with a Core2Duo processor at 2.0GHz, working mainly as a mediacentre. It does the job just fine, but I've noticed that when I use it for CPU-intensive tasks, such as direct-encoding video to stream to my iPad, the CPU-temps sky-rocket to well over 90ºC (i've seen iStat report 99ºC!), even though this doesn't affect performance at all and the system remains completely stable. The system fan starts humming at over 2000rpms and all, but that keeps the temperature that high. Heat sink temps reach around 70ºC...

I worry these high temperatures may be hurting my mini, which I love so much... Does anyone have any idea on what the max safe temperature for these processors are...?

Thanks!

Real Temp For Mac Catalina
M'lady has a brand new iMac and we're curious what the normal operating temperature 'should' be. The most intense thing she does on her iMac is play an online game that's pretty graphic intensive. I play the same game, and we both use SMC Fan Control 2. My machine typically runs around 28C - 32C when doing graphically intense things such as playing a game, hers seems to run about 38C - 41C even with fan settings maxed (we did this just to test.. and the iMac is very warm to the touch).
I've read many posts about heat issues with the iMac. I understand these issues as heat plays havoc on any computer. I'm also aware that my Mac Pro Quad-Core has large fans with a great vent system, however the iMac i see a vent up top behind the screen, and mesh below the screen, I don't know if the airflow is sufficient.
So... what's the normal operating temperature range? Will the iMac be alright if she runs her game in the 38C to 41C range for hours at a time?
Thanks for your time 🙂
