Safe iMac CPU Temps (Retina 5K, 27-inch, Late 2015)

According to iStat Menus, my iMac CPU Core temperatures have hit a max of 93 degrees Celsius during video encoding. Is this excessive?

I can easily push the temperatures lower by turning up the fan manually, but I want to know whether this is necessary. Also would rather not burn out the fan. Just wondering in principle what are the safe guidelines, so that I know when to back things off or amp up the fans.

This is 3.2GHZ Intel Core I5. (Retina 5K, 27-inch, Late 2015)

No, it is not. Were it excessive the machine would be shut down. The guidelines are programmed into the OS, the CPU, and the SMU. You needn't worry about them unless you aren't running any programs and the computer is overheating.

If you are using CPU/GPU intensive software then the hardware will run hotter. You should get used to it. Then read this:

Use Activity Monitor to Kill Runaway Processes

Use Activity Monitor on your Mac

Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity.

Should the above not prove helpful, then make an appointment at the Apple Genius Bar for service. If you need to find an Apple Store - Find a Store - Apple.
