CPU TEMP too HOT?

Hello, just wondering what the average temp for an i5 4590 chip should be around?
Mine is running around 32c when Idol.
 
Thanks!

That fine. Intel CPUs know how to self limit, if needed. They will flip a flag called PROCHOT and slow down to keep themselves safe.
 
Generally speaking 30ish degrees is as cool as they ever get in operation. Just the way thermal resistance and all that works out. Mine idles in the 30s, 35 degrees presently, despite having an absolutely massive oversized cooler on it, and being in a very open case.
 
Under load, they increase their temperature a lot. 60 degrees isn't uncommon. Most fan thermal controllers target the 60 degrees range meaning they figure if the processor is below that range, slow the fans down for less noise, if it gets above, speed them up.
 
Generally 75-80 is the range when motherboards go in to OMFGCOOLITDOWNNAO!!! mode and spin all the fans in the system up to maximum, in an effort to mitigate the temperature increase. Then in the range of 90-105 degrees, varying per model, is "TJMax" which is the max allowable thermal junction temperature. When that is hit, the processor flags PROCHOT and slows down to protect itself.
 
Chips can get pretty hot and have no issue.

I have software controller fans for my PC. I can adjust when the fans come on and at different power settings using different scales. I think they will come on with 40% power at 50 degrees and then increase from there.

According to Intel's ARK data sheet that cpu has a maximum case temperature (Tcase) of 72C.

At 32C it'll just be ticking over.

Intel have put a lot of effort into preventing their cpus from overheating for several years. The iX ones will automatically throttle their performance and if all else fails shut down rather than burn, though obviously relying on that to save you is a bad idea as is avoiding the performance hit as the cpu self-throttles.

The PC in my sig has two fans. Big, quiet 140mm Noctuas both running on 5 volts with fanless gpu and fanless psu.

One fan is on a seriously big Noctua cpu cooler and the other extracts air from the upper rear of the case. I can stress test the cpu to 100% on all cores for ten minutes and it doesn't go into performance throttling and the PC is almost inaudible from four feet away. The cpu never gets anywhere near 100% in normal use (in the real world dropouts would become a problem long before then).

The best way to sort out PC cooling is by careful experimentation in fan placing and voltage using things like Prime95 to load the cpu and speedfan or similar to monitor temperatures. If you're using a standard Intel heatsink on the cpu though the possibilities are more limited. The Intel heatsinks aren't very efficient and those little fans go round like mad to compensate.

The standard PC fan setup of one blowing in and one blowing put isn't always the most efficient either. The case design and the cards fitted can change all that. It's even possible for a fan blowing at the front to restrict the airflow compared to what a single fan extracting from fthe back can manage. My previous PC cooled best with just one big and slow case fan at the back blowing in and another very slow big fan blowing in at the front over the drives. The hot air exhausted through the top front CD drive bay which was empty with the cover removed.

Completely counter-intuitive and the opposite of "standard practice" but for that set of components in that case it worked. The inexpensive everyday PC built by HP, Dell etc. is made to a price and a "better safe than sorry" model. So they use cheaper components then configure them to keep things cool with noise reduction as a low priority in comparison. Doing things differently does mean you have to be confident about assembling and testing a PC though. Or go to a specialist DAW builder.
