I think the iMac has completely inadequate cooling for these very high performance CPUs to run at full speed.

Because of this, I don't believe I am getting the full performance that this CPU is capable of (benchmark results are way below the same CPU's typical performance in a PC or Hackintosh). Then the CPU frequency automatically throttles back to prevent overheating. The 4 cores' DTS temperature readings very rapidly reach their design maximum of 99 degrees C under full load. I have the (at the time) top end 4.0GHz i7 6700K processor (it's officially 4.0GHz with "turbo boost" to 4.2GHz, but in practice according to iStatMenus mine never exceeds 4.0GHz). I also have a 27" 5K iMac, though mine is a Late 2015 model, so the generation before yours.

If you can't, then you know it's most likely a software issue relating to a login item, corrupted font, or kernel extension.įor more info on Safe Mode, refer to: Use safe mode to isolate issues with your Mac. This will try and run diagnostics from the internet instead, so you will need to allow more time for it to complete.Īssuming the iMac passes this without error, I'd be more inclined to test your hardware in Safe Mode to see if you can recreate the issues you're having.

Note: If pressing and holding the D key at Step 3 doesn't work, start again at Step 1 and, at Step 3 press and hold both the Option D keys instead.

a brief description of any errors found plus further instructions.Once complete, one of two things will appear on the screen:.Wait for Diagnostics to finish (this typically only takes a few minutes).Immediately press the D key and keep it down until you see the Diagnostics screen appear.If you're particularly concerned about your hardware, I'd start with using Apple Diagnostics to test your machine.įollow the steps below to run Apple Diagnostics: If your iMac continues to run it without error, then it's passed the test. However, if you're wanting to use it, then you need to run it for at least 3hrs. So, for me, prime95 is the wrong tool for the job you're trying to perform (but that's a personal opinion). The reason it's popular for stability testing is because users will overclock their CPUs and then need a way to test how stable they are afterwards. Prime95 can be useful for determining stability, but I'm not particularly a fan of it as a troubleshooting/diagnostic tool. Reaching a temp of 95☌ is not surprising if the CPU is under heavy load for a prolonged period. Seems wrong to me, but who am I to argue with Intel? Apparently Intel claims its temperature spiking to 90 C during normal use and hitting 100 C during heavy use is normal. So no worries there.Įdit 2: After doing more research I've discovered this is a widespread issue with the Intel Core i7-7700k, and affects all iMacs that have it. Is that temperature too hot, or is this normal for an iMac?Įdit: After the system was idling all night the temperature went down to 45 C, which is of course a good idle temperature. I stopped prime95 and after my system was idle for a little while the core temperatures are now hovering around 60 C. Ordinarily I'd think that's way too hot but with the design of the iMac I'm not sure. So to see if there's a hardware issue, I started running prime95 in stress test mode to see if any errors were detected.Īfter running for about 20 minutes, I checked the core temperature readings for my CPU and they were all hovering around 95 C.

It's been having some issues lately where every now and then the entire system will gradually freeze, forcing me to hard reboot the computer. I have a 2017 27" iMac with a 4.2 GHz Intel Core i7.
