Help with chillers

post #1 of 5
Thread Starter 
A couple of questions about water chillers, coming off of this discussion.

First, how can you calculate, or otherwise decide, how powerful a chiller is needed? The aquarium chiller manufacturers have some online calculators you can use to estimate which of their models would work for a particular aquarium setup. But how does that kind of calculation translate to overclocking a computer, especially in cases in which the reservoir is very small (as opposed to a reservoir that is beer cooler-sized)? Are there formulas that take into account the TDPs of, say, the the overclocked CPU and GPUs? The bit-tech article used a Hailea HC-500A, which the manufacturer rated at 790W and 1/2hp, but Iosefini has said on this board, for example, that he has used I think an AquaEuro chiller rated at only 1/13hp, which sounds on the surface like it is much weaker.

Second, what factors can you go by to compare different companies' makes of chillers? Are they rated across the board in BTUs, for example? (I haven't been able to find any BTU ratings for Hailea.)

Third, how do you go about insulating or protecting the motherboard and its components against condensation damage? I am planning to be very careful with where I set the chiller temps relative to ambient humidity levels, but I want to take the extra steps to further protect the components against water damage just to be on the safe side, if it's not to hard.

One other question -- has anybody had any experience with JBJ Arctica chillers? They are expensive, but from reviews around the web it seems that they have a reputation for being among the most quiet, and quiet is probably my number one priority (after temperature control effectiveness). If not those, any other brands that are relatively quiet?

Not sure whether I've done this accurately, but I've tried to develop a way of comparing some of the chillers I've seen for sale online (in the US). I've converted liters per hour to gallons per hour and watts to BTU per hour.

I've used the following formula for the watts to BTU per hour conversion:
BTU/h = Watts x 3.412

Is this correct?

Here ya go.  Link

 

Thing is can you mix Titanium and copper?

 

Oh yeah you are right on the watts X 3.412=BTU/h

Titanium and copper should be fine.  I found this

 

Here is a link to the bit tech article for people to get into the know.

 

Just don't run your unit past dew point and you should be fine with condensation.

 

I might get one of these since I was thinking of building one anyways.  This is as far as I got.
