Homemade ZERO fan system, Watercool

I have just made my own homemade ZERO fan system,
watercooled..

http://www.webx.dk/oz2cpu/homemade-pc-main.htm

Maybe someone could get a few ideas,
I have tried to make it all as simple and easy as possible.

For more homemade PC modifications

Welcome to AOA's Forums, oz2cpu!

Very interesting, thank you for posting the link. The tubes alone have sufficient area to radiate enough heat? Is it possible to get the copper tubing that has "tabs" of copper on it to make heat transfer to the air easier?

Yes, the two 1.7 meter long copper tubes did work out fine,
see the result page for all temperatures..
But today I have improved it alot !!
I have just added 11 meter black garden hose ½" diameter.
I have placed this hose at the outher walls that are always cold.
Now my CPU block is 26C and my water temp is 25C at full load !
The garden hose costed only 1£ pr meter so this is really a nice way to cool it down.. I am sure I dont even need my two copper tubes anymore.

Interesting work in the PSU. How do you keep the HT and low voltage seperated when you're using a metal bracket across the two?

The washers used on the rectification diodes are not exactly high performance either, which is one of the reasons you're seeing such high temperatures on those rectifiers.

The other reason is that the two biggest losses in the PSU are losses in the transformer, and switching losses. The biggest switching loss probably comes from the rectifiers. Unfortunately, the next step up is to use a synchronous rectifier, which is somewhat more complex!

Many thanks for sharing your project oz2cpu.
Looks good!
As a machinist I love to see projects such as this.


You have inspired me to make my own set-up instead
of buying one.
I have a couple of old GTO heater cores that I'm
not going to use. One of those should be great
for the exchanger.
