What are ideal CPU temps?

I built my computer around 2 months ago and I now want to overclock my CPU. I ran the Cinebench R15 CPU test and my temperatures got up to 60 degrees Celsius. I am concerned. Is this too high?
 
Solution
Nope, that's perfectly fine.l CPU's don't start to really throttle until they hit 90c and they dont shut off until they hit 100c-102c. 60c under full load is WELL within limits.

I think the question of the thread should be "What are safe CPU temps"

Max temp on an i5-8600k is 100c. Which means > 100c it will shut itself down to prevent damage.

What kind of CPU? Rough estimate I would say 70-80 is safe.Personally I wouldn't like to run > 80. The higher you approach max, the more degradation will occur which can decrease longevity.

I have the i5-7600k. I have another question. I overclocked it to 4.4 GHz, but in Cinebench it still says it's at 3.8 GHz. Is this a glitch? My score did go up from about 600 to 733.

Cinebench always shows the base clock speed in the left column I believe, it is probably running at 4.4ghz. You can use a program like CPU-Z or HWInfo to make sure.

Thanks, it is 4.4 GHz.
 
just to correct something said above, intel CPUs do not shut down when they hit their thermal limit (ie 100 or 102C)
but rather, they throttle. I only know this from experience of relying on Asus's AI Suite III which never showed a temp above 67C, even when running 100% load. Then for whatever reason, i downloaded RealTemp and it was showing my temps, when running the 100% load while rendering video files, it was showing the temp hit 100c, then dropping back to 98C and immediately bouncing back to 100C. I then downloaded Intel's XTU utility, and it showed the same 98-100C temps, bouncing back and forth

the thermal limiter will drop the cpu's load until temps decrease below 100C, then let it go back to near full load and again, as soon as it hits 100c again, it will throttle the CPU

that thermal limit in the CPU saved that processor - i'd been rendering video files, 3-5 hour jobs, 1-2 a day, for 3+ months, relying on Asus's crapware utility (it was an ASUS mobo). To this day, 3 years later, when i run a benchmark in intel's XTU and compare it online with other users running the same CPU & mobo, i'm within 5% of the top benchmark, so i'm confident the intel CPUs are bullet proof, temp wise
