Hi all, i recently built a new computer and i've been running it through prime95 to test how hot my cpu gets on max load.

My cpu is a I5 4690k "no overclock" with a 212 evo cooler.

With prime95 on the small FFT test my cpu maxes out at 60 degrees after running the test for an hour or so, is this good?

Also when gaming my cpu gets up to around 55 degrees "playing ffxiv max settings".

I'm kinda new to prime95 so what i want to know is the following, because prime95 got my cpu to max out at 60 degrees on the small FFT test does that mean that gaming won't cause it to go any hotter than 60 degrees?.

I guess what i'm asking is, does the prime95 FFT test show the max temp my CPU will ever get to? or doesn't it work like that.

Thanks for any replys.

Alex.
 
Hi,

That is completely fine, those temps are completely normal and you have nothing to worry about. You should be worried if your CPU temps hit 80+ C when playing games but at your temps currently you're all right.

I guess in idle you have about maybe 20-30 C?

Regards,
 


idle i get around 35/38 degrees

 


Yeah, again. Those temps are fine.

Nothing to worry about! :bounce:
 


Sorry to be a pest but do you know if the small FFT test that's showing me 60 degrees is the hottest my cpu will get? if so that'll put my mind at ease, i'm constantly monitoring each game i play with MSI afterburner because i'm so paranoid about temps ;/
 

Prime95 will usually give the highest temps as it stresses the CPU more than any game will
 
Prime95 being an intensive stress test should more or less a worst case scenario. Chances are most if not all games you play won't stress the cpu as hard meaning games shouldn't cause temps as high and certainly not higher than p95. Your load temps are really good so I think you're over stressing. No need to monitor temps all the time like that. Running the cpu at stock with a decent aftermarket cooler you're fine. Even those who overclock typically don't watch temps constantly, that's the purpose of running a few stress tests. To keep 'current' they only need to be done once in awhile or when problems become present, once an overclock is set and tested unless anything major changes (swapping cooler, changing thermal paste etc) it really doesn't need to be done all the time.
