Instead of the regular rad type setup, you could think about what's called a "Bong Cooler" that is a type of rad setup that can cool the water to below ambient temps, sometimes called an evaporative cooler.

Bong coolers are great, and depending on location can really be effective. (Dry climates will work better than humid ones).

they are a bit more work though because you will be adding dust and stuff directly to teh water, so your loop and blocks will have to be cleaned more often, plus you will need to add water to it frequently.
they are also noisy-ish as well, although it would preclude the need for a whitenoise generator

Still for those used to LN2DIceing for benching, the maintenance will be pretty minor

I would really like to do one of them some day

You could set it up so that it uses a AC paper type air filter on the air intake side of the box, that will help keep crap from getting into the cooler. As long as the fan is running, no water will get to it.
I also have to say if you can get the return water coming back as a mist rather than a stream, it will become more efficient.

If I can get the materals together, I can do that as a project later and would love to set one up sometime just to see how well it works.

OK a quick update~

I did finally get around to TEC cooling a Cpu. I have begun testing on a FX-6100 that has been de-lidded. And to say the least, the cpu doesn't exactly run cool under normal air, and I skipped using just a water block altogether.

In the picture above, I have the Cpu set up minus a water chiller loop. Imstead, I'm using a faucet tap to provide a little cooler water temp to the hot side of the TEC so that I can remove the heat properly enough without saying I had to use Ice or a chiller method (which hardly ever works) So I suppose you can say I cheated a tad. The tap water temps are around 45f deg, so not really cold, but at least cooler than a standard water loop.

I hope to have a few pictures later on today for you guys. I have a couple of screen shots as well.

So far.....

Clocks at 4ghz and 1.250v is a sweet spot. constant frozen cores except on a 6 core load. I think maximum temps got to 27c both cpu and core temps. They level'ed out while running WPrime 1024m back to back a couple of times.

While benchmarking (AquaMark or Pimod) single thread stuff, core temps stayed reported as 0c and the Cpu temp might have hit 10c give or take.

The plate between the TEC and Cpu is 1/16th inch thick 40mm x 45mm, so it's a little bigger than the TEC. I am using the GTZ water block as stated I purchased for this project.

Hopefully you guys get a kick from this like I do. keep you eye out for pictures later today, I just gotta get them off my camera and transported to a PC with some internet!

TTYL,

Is that Di electric grease? I use eraser, yeah you have to take the brackets off the P67 + Z77 boards as there are tinny openings if not. It just makes it easier n cleaner, I used that grease one time! Got it all over the place,need some more let me know no need for the rest of it.

[ShrimpBrime]

Philly sorry for the delayed response....

That is petroleum jelly. The stuff works great. But yea, I use di-electrical grease as well.

The black bead is Permatex High temp silicon gasket maker. Used primarily in automotive, I apply it for a permanent seal. It's water tight and stand up to the cold really well too.

I thought the bulldozers do 4+ GHz on air cooling?

With all cores running, the TDP of the cpu exceeds that of the cold side of the peltier, which is 136w cooling power. (roughly)

I can get a 5ghz submission with all but 2 cores shut off.

4.6ghz on 4 cores is about the max.

Frozen at idle at any speed......

TECs are a challenge no doubt.

Speaking of "air" cooling, I've run a sempron 140 without a heat sink at all. I had the cpu around 2ghz .9v (or less) and a fan on the IHS plate. Shut off a core it's a 25w cpu, lower volts and clocks, you don't need a heat sink

[kikicoco1334]

thb, 4.6 and 5ghz is about the same. as far as gaming goes.

some guys here may think it differently but still...
I have my chip at 4.2 and that's as far as it'll go

I kinda gave up on TEC at this point.

[ShrimpBrime]

I give up on them and then take it back up again.

it's amazing how some of the lower end cpu'z will stay frozen under this TEC. But for some reason, I always try cooling massive TDP output processors instead.......

Perhaps next time, I'll find something a little lower end just to play with again..... some day
