[SOLVED] Trying to go sub-ambient

[arthurrag]

Hi,
Would like to hook up a aquarium water chiller to my system. Is it feasible to disconnect the cooling likes of my present cooler and loop in the chiller? I know about the possible condensation possibility but would not drive it below the dew point of the present ambient temp. I was thinking about building a new PC but I really do not need the speed. Just a project I guess. It is sort of a hobby for me.
Anyway, Id like to see if I dropped the CPU temp to 55 or 60 C if I could get more than the current 4.4 Ghz out of my processor.

You would need to build a dedicated system instead of hacking up an AIO...

 

[arthurrag]

I could do that but it would be a lot more expensive. I guess you are talking about a custom loop or an AIO with the quick disconnect hoses?

"sub ambient" would be in the range of 22C or lower.

And going from 60C to 55C gives exactly zero performance difference.

Im presently pushing 80-85C when I overclock all the cores to 4.4Ghz. The ambient is 22C (I stand corrected for my mixed temperatures) The room is 22C. The spec on the chiller states it should cool 10+ degrees F "pulldown". This is an aquarium chiller so assuming the fish water is at ambient, 71F I would pull it down to 60F which is about 15C.

On a side note, USAFRet, what did you do in the USAF? I was in for 9 years, worked jets and Biomedical equipment.

Jets and programming.

There's a major difference in cooling a static tank of water, and cooling an active heat source like a CPU.

 

[arthurrag]

Yes, I can see that point. I still think that it being such a small amount of water that running it full cold would bring the CPU temp down. Maybe not. Still the question remains. If I did get it down and kept it around 15-17C could I up the CPU clock? I guess I will just have to give it a try. I am just wondering if I am up against the wall with the CPU's capabilities.

 

[USAFRet]

One of the main difficulties with this type of project is in transferring that CPU thermal load into the fluid, no matter how cold that fluid is.
You only have about 1.5 sq in to work with.

And to be clear....you're talking about the fluid temp at "15-17C", not the actual CPU. Right?

 

[arthurrag]

Well I would like to get the CPU temp as low as I can without creating condensation. The Chiller can be adjusted to 7C minimum. Thanks for your help. I will think about it and if I do it I will append to this string and let you know what my results are.
