New watercooling rad/water cooler

I saw this thread on coolhardware and decided to make one myself.
http://www.coolhardware.co.uk/module...&t=524&start=0

This pic shows the basic pryncipal better than I can explain

My version is made using a baking tray with holes drilled in it and two 120mm fans, suspended over my existing huge res.

This thread details my setup untill today
Finally watercooled

Ok, ill just post some pics up to give you a basic Idea.

Front view.

You can also see on the above pic that the pump is suspended by string as are the fans, this is done to reduce vibrations and corresponding noise and is a very effective way to do so.

This pic is a top view showing the holes in the tray and fans.

The blue foam is to reduce the water velocity coming out of the inlet pipe as it was splashing about and was quite moisy, that that foam in place its much quieter (although I need a bit more to get it silent)

It works better than my homemade rad.

Water is 2-3*c above ambient with a 116watt load.

The tray has started to go a bit rusty allready so ill have to make a copper version once ive decided on the best design.

I think ill be able to get better temps if i push the air between the tray and the waters surface rather than just blowing onto the top.

Wonder if it would make much difference if you redirected some of the air into the "duct" created by the surface of the water in the reservoir and the bottom of the pan?

You might want to have a larger number of smaller holes though if you did this.

Ive been thinking the same thing Aidan, ill rig up some ducting at some point

I think the optimum design will be quite differnt looking, but working under the same pryncipals

The tray is plated steel so there shouldt be a problem with corrosion on the waterclock.

THis is only a test setup, if it works out ok then ill make a copper version.

Long bolts of fabric that wick up the water, and allow the water to flow down them in to the reservoir, with a few fans blowing on them, would probably work quite well for an evaporative cooler.

Or even a couple of shower heads in a 15 gallon trashcan would do nicely.

I'm not big on evaporative cooling myself, I'm only 14C above ambient with very quiet radiator based setup(Morgan @ 1.46GHz 1.95V).
