Prime95 Small FFT lasts forever

I have been doing a small FFT stress test for the last 2 days. 

 

How long does it last? I had expected it to have finished by now but it's still going. Does it go on forever until you tell it to stop?

 

HOWEVER 

There was a text box asking me to basically input a number. I entered 10/20 thinking it might affect the number of times the RAM or something would be tested. However: 

 Suggests that the number was asking me to input the number of cores. YIKES! I have a i7 4790K which has 4 cores with hyperthreading. Would this have caused a problem? Maybe caused any harm to the CPU? I guess not. The main thing I'm concerned of here is whether it negatively affected the stress test or not.

 

Please note that my version is 26.6 as the most recent versions would not be appropriate. Apparently this was the last version that was good for stress testing an Intel CPU with. My highest CPU temp is 72 degrees celcius as I have a Dark Rock Pro 3.

In stress test mode it runs forever unless you stop it, or if it finds an error.

 

Latest 28.xx runs great on modern Intels, but it will use the CPU more intensively and give hotter temperatures as a side effect.

I'm pretty sure Prime95 tests last forever, because the program is used as a stress test, not a benchmark.

What would be the effect of running more threads/ cores than it has? Would it just make the stresst less effective?

There wouldn't be any practical effect on the test.

I have a blog! And a list of guides I've posted
