makeandbakeasandwich,
Here's the recommended operating range for Core temperature:
80C
Hot (100% Load)
75C
Warm
70C
Warm (Heavy Load)
60C
Norm
50C
Norm (Medium Load)
40C
Norm
30C
Cool (Idle)
25C
Cool
Core temperatures in the mid 70's are safe, so just keep it under 80.
Please read this Sticky:

Pay close attention to Section 13; Thermal Testing @ 100% Workload.
drkatz42,
When you recommend Prime95, please be more specific. In case you didn't know, any versions of Prime95
later than 26.6 should NOT be used. Here's why:
Core i 2nd through 6th Generation CPU's have AVX (Advanced Vector Extension) instruction sets. Recent versions of Prime95, such as 28.9, run AVX code on the Floating Point Unit (FPU) math coprocessor, which produces
unrealistically high temperatures. The FPU test in the utility AIDA64 shows similar results.
Prime95 v26.6 produces temperatures on 3rd through 6th Generation processors more consistent with 2nd Generation, which also have AVX instructions, but do not suffer from thermal extremes due to having a soldered Integrated Heat Spreader and a significantly larger Die.

Run only Small FFT’s, because it's a
steady workload with
steady temperatures. 10 minutes is plenty of time.
Use Core Temp to measure your temperatures -

Your Core temperatures will test 10 to 20C lower with v26.6 than with v28.9.
