aida64 temperatures

[random2234]

so i just built a new system with a intel core i7 6700k running at stock speeds with a noctua nh-u14s as my CPU cooler and decided to use Aida64 to stress test my system. i ran it with stress CPU checked for 4 hours and my max temperatures went to around 46-50 degrees on the individual cores and 49 degrees for the cpu reading. i then ran it again for another 4 hours this time with stress FPU checked and my temps went higher with 63-70 degrees for the individual cores and around 67 degrees for the cpu reading. 

 

im wondering is it normal for "stress FPU" to produce higher temperatures than "stress CPU" 

[Electronics Wizardy]

Stress FPU is hotter than CPU as the fpu makes more heat the the integer units.

Yes, it's normal. You might see 100% usage on both tests, but the FPU is actually pushing the CPU harder.

The FPU test puts a very heavy stress on the processor, both load-wise and thermal-wise.  It is a very unique test in a sense that not many other stress tests or applications are capable of pushing your processor that far -- using AVX, AVX2 and FMA instructions indeed helps AIDA64 to achieve that level of stressing.  Whether you deem it is useful for your particular usage scenario or not is completely up to you to decide   If you use AIDA64 to measure your temperatures while running applications or games, and you can see much lower temperatures than what you did while running the AIDA64 FPU stress test, then you may have some headroom in upping the CPU clock and/or voltage.
