Watr Chiller

I picked up a water cooler from a friend. The kind that holds the bottle on top. This thing will form ice in a very short time with the thermostat bypassed. I am going to set up a chiller on my rig. I am still in the planning stage now. I will probably add it to the loop with the thermostat to see what id can do like that. I am not sure if I want to go for extreme cooling or not. Alot of work in protecting everything from condensation. I will post some pics of the unit tomorrow, and as I progress. I still have to pick up a WB for my Video card. The DD NV68 are dropping in price, maybe that would work great with some chilled water. Wish me luck.....

Anyone know of some good CPU GPU insulating articles?

I think a lot of people use vasilene or another non-conductive grease.

I can't wait to see those pics!

Somewhere around here, I've got the parts for building my own chiller system as well, but I wasn't going to use actual water, as my goal was extreme cooling (hopefully somewhere around -10C or -20C). If you go to the hardware store you can get a spray plastic conformal coating, which will protect the relevant portions of the mobo from condensation quite nicely. That just leaves the area under the CPU socket, which I was going to seal with silicone rubber on the inside and outside edges (socket A at the time I was doing this).

Can you get me some information off the compressor in the chiller? Manufacturer and model #? With that, we can get the specs on the compressor and get some idea of what it is capable of.

Will do . I still have a unit from a medical device. The condensor was small and needed a high power fan to cool it. It used a water jacket coil to chill the water. Just too loud with the fan. I tried a lower speed fan and it lost some cooling capacity.

I will get the info tomorrow with the pics...

BTW.. thanks for the insulating tips. I have seen a few articles around the net. I will have to do some research before I am ready for extreme cooling....

Use Dielctric grease, not vaseline. It is meant to not conduct elctricity and keep out water. We use it on our camera and light connections underwater.

Here are some quick pics.

After turning up the thermostat, it managed to freeze the water in the res area solid in a few hours....

I will clean it up and post better pics. Been busy at work lately.

I am thinking of removing it from the cabinet and building something a little nicer for it to live in....

Wow, that looks like a pretty funky piece of kit!

What sort of housing are you planning for it?

Not really sure. The condensor is quite tall. It is passive though and almost completly silent...

Any ideas on an enclosure...??

Have you been able to get a good enough look at the compressor to get some numbers off it?

you'll overwork the compresser quite quickly with a cpu methinks. might think about adding some sort of fan over the condensor! Mind you, if you were not using this as your sole source of cooling the water, it might hold up 24/7.

I wasplanning on adding a fan to cool the compressor and condensor. Plus I am not going for super cooling. I figure I can use the thermostat to control the unit to keep the water and cpu to a acceptable temp. I was also thinking of using a copper coil immersed in the tank to cool the pc water.


Wow, I hit 10000 for FAH.....woo hoo

congrats.

You could, however the heatload of the cpu is quite alot. let's put it this way...a sinlge 120mm BIX rad is not enough to cool MY cpu @ 1.5v, and 3ghz, without a screamer of a fan on it. Took 65 minutes for it to melt 4 kilos of ice in the water.

Manufacturer?

Being a 1/20 hp compressor, you're definitely not going to get extreme temps out of it when cooling a CPU going full blast, but I gather you weren't intending to go extreme with it anyway. I'd be surprised if the thing can handle more than about 100w, though, and maintain a reasonable water temp, and it's going to be working hard to do that.
