CPU Temperature on i5

[Dylan_49]

I am getting about 50-60 degrees celcius according to Open Hardware Monitor and I'm curious is that an okay range? I am gaming and have tabs open and such. Is that a safe range for my i5 4590 that I just installed? When should I be worried?

 

[smorizio]

50-60 whe ndoing nothing is too hot. in gaming that fine. whe nit read the high 60-70c or more that when you should see why the temps is running hot. 50-60c is good temp under heavy load.

Your CPU's max temperature is 100c. Under heavy loads, you probably won't want to be running 100c, but I wouldn't worry if you see it peak in the 80's, for instance.

50-60c is perfectly safe, if that's as high as it goes under your typical usage.

Max safe Core temp for that CPU is 77C. It should throttle at 100C.

Your temps are fine.

I'm idle right now with 55-60% celcius...hmm...is it worth putting my CPU fan on max speed? I just got it not sure if I should.

I tried to find where the guide sourced those numbers, and could not. The articles cited didn't actually support the numbers in the guide.

Tcase on the i5 4590 is 73c, but Tcase is not core temperature, but rather is temperature at the top of the heatspreader, and there's no way to measure the temperature of the top of the heatspreader. On Intel's mobile CPUs, max safe temperature is throttle temperature, or 100c for Haswell and Skylake CPUs.

^ Physically, it's the same die. I would expect the same core temperatures to be safe.

Idle temperature is irrelevant. What is your loaded temperature?

If you idle that high, either your room temps are very high or you don't have enough air flow in your case. I would also try something like core temp and see what it says your temps are. Never just use one program 100% of the time.

Just a heads up, Tcase is actually 'delta case temp', meaning the delta above room temperature (~21C). So 73 Tcase is actually more like 94 C.

We're derailing, but according to Intel:

"Case Temperature (Tcase) is the maximum temperature allowed at the processor Integrated Heat Spreader (IHS)."

I assumed that was an absolute temperature in Celsius.

Idle temp should be in the high 20Cs to mid 30Cs depending on the ambient temps and case air flow. If yours is at 50-60C at idle, you have something wrong. Stock cooler? Check that all 4 mounting feet are flat on the m/b and the black posts are equally pushed thru the white posts on the back of the board.

My fan is secure, yes stock cooler. I also accidental picked up my fan after already putting it down in place so the thermal was kind of spread already then I reseated my fan so maybe that has to do with it

It is hot outside but it's not hot in my room, I think it's fine.

 

[Dylan_49]

Under a decent load just now while gaming I just hit 66 celcius max temp and I do plan on streaming as well so this is why it worries me. Maybe I messed up the thermal paste when I had to take off the fan and readjust it, should I buy thermal paste and reapply some?

 

[Ecky]

If you're not seeing temperatures above ~80c, you're definitely fine.

 

[Dylan_49]

Hmmm, okay.

Once compressed, the TIM should not be disturbed again because removing the cooler and compressing the TIM a second time will introduce microscopic air bubbles into the mix. Air is a poor conductor of thermal energy. That may (or may not) be your problem with your high idle temps. I would eliminate that possibility by cleaning off the old TIM from both surfaces and starting over by applying fresh TIM in this amount and this manner. http://i.imgur.com/NHjFDEx.jpg

I was able to get it under 60c under heavy loads just by applying a very small pea size of new thermal paste. I didn't think so small of thermal paste would be so good.

Excellent. Yes, the TIM is actually only desired to fill in the microscopic voids in the metal surfaces. That way thermal energy will transfer between surfaces better than if it had to pass thru air. Anything more than that amount of TIM will begin to degrade thermal transfer.

I experimented once and put a dab on each surface, wiped it back and forth to cover the surface, then wiped it away with the edge of a credit card leaving just what filled in the pores, and then assembled the cooler like that. Temps were satisfactory, surprisingly. But later I replaced the TIM in normal fashion because I didn't trust my own results.
