what are "good" idle temps

[crazymonkeyzero]

Hi guys,
I'm kind of new to computer building (my second build). I just finished building a workstation running the Intel Xeon E5 2630 (95W, 6cores,12 threads) I installed a closed liquid cooling kit ( http://www.newegg.com/Product/Produc...82E16835203006 ) and my idle temps are 30-31 degrees C. I was just curious whether this is "good" or if it should be better for what I have. I will not be overclocking (not that Xeons can overclock anyways) but the computer will be on 24/7 running calculation software. Thanks to anyone who can give their opinion.

The general rule of thumb for non overclocked systems:

If its not throttling, the temps are fine.

Those are great temps. What are your full load temps. That is what is important here.

I will try running "full load tests" today and report back. I was going to use "BurnInTest" by passmark. http://www.passmark.com/products/bit.htm Do you recommend prime 95, because I have never actually used it and don't want to fry my brand new cpu (if that is possible)

I don't know how legit this is, but pinning all 6 cores to 100% for 30min the max core temps I got was 42 C. This was with the passmark burn in test.

26c is my idle temp on my 2600K Intel stock cooler.

35-40C idle here on i5 3570K, stock cooler. Completely normal.
Around 75-80C under 100% Linpack load, completely normal too.

Just ran 2 hours of prime95 large fft torture test with all cores at 100% and max temps were 46C. Hope this is good lol.

if those are correct those are amazing.

Yea my cpu never went above that value for the entire 2 hour duration. But I think my setup helps as well. I have a Bitfenix Shinobi XL case and have a 280mm and a 120mm intake fan and 3 Gelid Wing 120mm fans (love them) on the top as exhaust as well as the 120mm, double thick rad plus fan which came with the intel liquid cooler. The only thing I really changed from out of the box was the generic TIM intel provided. I chucked it out for some AC MX4 which I applied using the line method.


BTW, what would you consider "normal or average" in these conditions. Just so I can get a baseline for my temps.

Interestingly enough, you have a legion of Intel engineers trying to figure out how to always keep the processor running at Tcase. Your specific processor has a Tcase of 77.4*C. Even using an incredibly unrealistic zero degree delta between Tcase and whatever PECI reports, that means keeping your cores hovering around 77*C.

Realistically, the cores are going to be at least in the 90's. You can definitely keep fretting about your temperatures here; but I'm a big fan of trusting the people that design the processors we know and love.

 

[ShintaiDK]

Nobody measures Tcase because they cant without modifications and 3rd party sensors.

Tjunction is whats measured.

These temps are useless as really only ambient room temps in conjunction makes posting them relevant.

If I bump down my AC, my temps go down as well.

A real computer never idles.
