Cryobath chiller

[Xenogias]

I want to get some input on this particular unit before going ahead and making the purchase. I would like to adapt it to a liquid cooling system with or without TECs depending on which gets better temps (most likely without if it works as well as it advertises). This would be used to cool cpu, gpu, and northbridge.

according to various product information sheets it can remove 120w of heat and at -60C, 160w at -45 and 180 at -20. It uses a dual cascading system and i'm not sure what kind of refrigerant. I was thinking of using that cold finger (the external evap) in a small largish reservoir and upgrading my eheim 1250 to the 1060 (or whatever the 600gph model is) to keep the liquid moving fast enough. If you dont think its worth it let me know, Total cost would probably be around 300-350 shipped freight and then another 20-30 to clean it up and clean or flush the compressors with new oil and refrigerant. What do you guys think? my other option is a prometeia for the cpu and continuing to use my water/TEC loop for the gpu and adding a water/tec block to the the NB. I just want to get some info from a bunch of people so you might see this post in other forums

thats some cooling with gonads!, are you sure you can modifie that unit for that purpose, if not you'll be stuck with that gray box( its not much of a looker)

The 1060 is the 600GPH model.

You'd need a fairly large resivoir to fit the coil in, I suppose, and then you'd have to protect all your plumbing from condensation. Coupled with a BIX if you go TEC, this should work wonders.

I dont think i would need a radiator at all as cooling the water with the air can only take the water down to the temperature of the air, and by all accounts the water should be much colder with this thing.

I'm actually a little concerned that the unit will not be able to remove enough heat. I know its capable of pretty damn low temps but as far as dealing with a constant heat load I'm not sure. I think these things are normally used to cool lab equipment. I dunno, i suppose the other option is to build one myself. I was thinking R404 because that seems pretty doable, but a lot more work than what i planned for this cryobath. I havent ever really seen a water chiller that got below -30c. What do you think the heat load of a heavily overclocked P4 at 1.75-1.85v would be?

Hi Xenogias,

Be advised that a used cooler runs about $700.00 USD.

For the cost of a new one, you can buy a lot of cooling in a Vapochill or similar case.

Just my two cents worth.

Take care..........

Well, here's how I figger it. 226w TEC on the CPU, so ~ 325w load with OCed CPU. 80w TEC on GPU, so 100w with stock speeds. 50w from nb. 475w load total. Sure, you may be able to keep temps at ~40C, but thats counting if the water stays in the resivoir long enough to become cooled.

Are you buying this new or used?

[Xenogias]

this is used. The damn thing would be about $4000 new. And Like I said, I can get it for about $300-350. I'm looking into alternatives like building my own, but it just seems like this would be a nice one-shot deal and I wouldnt have to do much brazing, welding, or anything else. If the water temps are low enough I probably wouldnt use TECs, but it all depends on the core temps i get with and without them. I want something comparable to direct-die phase-change on the cpu and something much colder than a 172w tec cooled by room temp water for the gpu. Northbridge cooling is really of secondary concern.

if the cooler can really do those temps then it looks like a good deal. the pump is a 1260, not a 1060. a long time ago it was the 1060. same pump, new name

[Drake]

er, well I was close enough :rolleyes:

I suppose this is a good deal, as for the same money you can cool your CPU comparitively, and this is a tad more expandable.

Good deal, says I.
