You set the temperature to 30 deg C or above and no problem with the dew point but the chiller liquid cooling circuit has to be separated from the chip cooling circuit. It can still be done with a single pump.

So you would run a heat exchanger between the two loops then ?

Lots of cheap heat exchangers on ebay :) .

Of course the chiller is not cheap and, presumably, would generate its own heat as well.
Without dialogues, if you tell them you want something real bad, you will get it real bad.

No (other) heat exchanger if there is a chiller. The only tricky but not so much part is to have a passive mixer that would diffuse/mix what comes from the two circuits together before it enters again the chip circuit.

Not that many actually. These China sites offer much better choice and the price is comparable.

The one I pasted above is ~SGD250-280. Yes, it generates heat but it can cool more with the same footprint. It will also be likely less noisy. I used to have a 250l fishtank, here in Singapore with such chiller. For two servers probably not worth to have it.

I just can't resist and have to tell how happy I am with this S$60 PowerEdge1950. It's such a nice platform to learn the servers. I invested another S$50 and now my PowerEdge (PE) is an 8 core machine (2x 4-core Xeons). Yes, this is how cheap it is to get a matching pair of the Xeons from Ebay, all inclusive. In terms of computing power I don't think anything can bit this price.

I made it into a multimedia backup encoding station so if I have anything queuing from another computer it is sent to the PE to encode. It runs either Linux or Windows 7 depending on the projects. The only problem is still the noise but I put it under a sofa in the study room and it is bearable. Still I am planning to convert it to a liquid cooling.
