2600k; How Hot is Too Hot?

post #1 of 14
Thread Starter 
Got a few 2600k boxes running at 5.0 - 5.1ghz or so, for most of my purposes, they don't really crunch away for extended periods of time. I use them for distributed rendering, so they pick up a frame with my main computer and render it...this usually only lasts for 15-20 minutes and then they take a break and drop back to 24 - 30 degrees.

I live in Canada and tend to leave my patio door open so the ambient is quite cool, the 2600k render boxes used to only hit 73 degrees or so under full load for hours. With summer coming in though and ambients going up, the highest I've seen is now 82 on a couple cores of one of the machines. It takes around 1hr+ of non stop rendering on a single frame (no breaks in between) to hit this temp, typically they'll be more around 65-70 under normal usage.

Is there any reason to be concerned about this at all?

Well, max is 98C so it shouldn't hurt but I like to keep my temps below 80C....

How high are the voltages? If they are below 1.4 then you should be fine, but it probably isn't great for the processors.

They've hit 82c? To me, that's too hot. No higher than 75c in my books. But then again my CPU doesn't even reach 60c after hours of heavy load.

At those kind of overclocks and temps I would be worried about seeing degradation over the course of a few months, some may argue, but high heat and voltage @ 100% load for duration definitely reduces the life of a processor. It may not be drastic, but there is a reason why people do not prime their machines at high overclocks/voltages.

5.0 @ 80-85C is fine if your going to be gaming on it or something, but if your going to be keeping it at 100% load for longer periods of time, I would personally not want to see more than 75C max. If its just rendering, your better off dropping to like 4.8 GHz for the summer months when your ambients are up.

Just my two cents

All render boxes have Corsair H70s with Noctua fans installed.

Maybe I'll drop them to 4.8ghz in the summer months to be 100% sure about proc degradation. I'm sure that 82C is totally fine to run for hours on end without any real problems, it's just a peace of mind thing really I guess.

The voltages are around 1.462 to hit 5.0ghz, maybe I should see if I can drop those a little more first.

With your temp its perfect, if its stable just leave it.

82c @ 1.462v is not perfect O__O

Seriously, either buy a NH-D14/Silver Arrow/Custom Water Loop to get those temps down, or back the speed+volts down.

I would never let my temps get above 82c in a stress test.
