CPU temps, is there a too low?

[amenditman]

I am running a Cooler Master Seidon 240M water cooler on my desktop machine.

It is really keeping it cool and I am wondering if there is any such thing as the temp being too low.

 

Too high is really bad but that doesn't always mean the opposite is true but sometimes it does.

On my Chevy truck, if the transmission doesn't reach a certain minimum temp it does all kinds of random screwy things.

Rule of thumb:

 

In electronics, heat kills.

 

You could run your processor down to nearly absolute zero and not hurt it any. Yet, if you run it a few degress past its rated operating temp, you could permanently damage it.

 

Now you know.

 

Oh, and it's different for mechanical devices such as your truck's transmission. Metal and lubricants behave optimally at certain temps; above or below these temps may cause issues.

By the way, my air-cooled processor runs at about +59.0°C (+136.4°F), so your +24.5°C is making your processor very confy and happy.

Eric,

 

Thanks for info. I thought that, but had no knowledge basis for the thought. Never seen it mentioned anywhere.

 

When I run a stress test on this machine to get it to use all 8 cores at 100% it spikes to a whopping 47 C.

 

Not bad!

116F, huh? You wouldn't even warm your fingertip too much on that.

[amenditman]

It's pretty warm when it is exhausting right up your leg!

That's like a 2000w Wawasee linear amplifier I once ran on my CB radio here at the house. It was tube amp. I kept in under the desk. In the wintertime, it kept my feet and legs toasty warm.

 

 

The guy who had it before me literally melted his 1/4 wave ground plane antenna using that box.

How did it feel in the summer?

I didn't have it long enough to find out. I was afraid Uncle Charlie (FCC) was going to be knocking on my door. There had been spottings of non-descript white vans with omni-directional antennas mounted on the roofs going up and down the blocks in my neighborhood at that time. I sold the JB2000 and reverted to my old Swinger (250w) amp. That was more than enough. 2KW on CB is a bit of overkill, unless you're trying to talk to New Zealand on a regular basis.

My Core2Duo E8500 idles at 25°C with the stock Intel HSF on a 15°C day, and hits a little over 40°C under heavy load such as media encoding.

GPU which is Nvidia 560Ti idles 25-27°C; it is a special SuperCool version with lots of fancy heatpipes and stuff.

The main thing is to have good flow of air through the case.

 

If you look around for overclocking tests you will find some running with dry ice and even liquid nitrogen. 10 years ago, Tom's Hardware clocked a P4 at 5.25 GHz At -196°C. So no, your temps will be fine.
