Water Cooling

How about this Water Cooler for an Aleph???

together with one of these



Please give me your opinion.

This has been discussed for the Zen amp.

What is "one of these"?

If you want to use this cooler AND don't want a huge water bill, you must cool the water somehow = heatsinks or radiator plus pump.

Water cooling is good if you must remove lot's of heat to some other place.

I think you missed the system under the link?

My oppinion. What exactly is YOUR goal? If it's for looks, then nothing beats that passive radiator you have linked to. Add some blue dye to the water for a complete package.

But in my book, how to save a few $$ is usually what I aim for. If I am going to consider a water cooler it's because it'll save me over the cost of the huge heatsink. I think right now most CPU systems won't. There are probably some DIY varients that might however.

I have a large heat exchanger (the outside unit from a commercial air-con system) that will easily shift many kilowatts of heat, could be ideal for that Aleph 1.2 triamp project!

It is available FREE to anybody who can take it away! (i am in south east England). It's too good to throw away, but i can't hoard it any loger as i need the space.

I have had the vision of using a computer water cooler to augment a standard passive heatsink. Generally, the computer water cooler can not cool enough by itself but what if we took a heat exchanger and bolted to a standard heat sink? Using a conventional cpu water cooling pump and radiator, it may be a good combination.

I was also playing with the idea of watercooling my SOZ. There is only one problem. To use the normal pump like those used in aquariums, the water temperature should not exceed 35C. This is quite difficult to hold if the MOSFETS are getting hot (50C). The computer WC are designed to dissipate 130W ...

You can use another pump ... one that can handle a higher temperature. if you can find one, then it s fine. Another detail is that the dissipator must be of the same metal than the waterblock otherwise you get oxydoreduction which is a chemical reaction that will gradually destroy your waterblock (ex: Waterblock in copper and dissipator in aluminium).

I have watercooled a few computer projects - for me the best pump was a spare pump from the heating system for the house. This handles very high termperatures and will run quietly forever without problems.

To get around the problem of reactions between the various metals in the system and the water (and to prevent growths in the water) simply add anti-freeze.

better use 100 % antifreeze if you have bothe copper and aluminium in the system ....
