First of all please apologize me if my english is not too good.

Here are some pics of my homemade watercooling system
Pump Hydor L20 (700 l/h)
Waterblock - Alphacool NexXxoS HP

Radiator - "Heatercore" of an opel corsa 1.2 made of copper and painted.

Fan - "Blower" from a Mercedes Benz

For the filling of the circuit I choose for a simple “T” instead of a reservoir that only serves to raise the chances of a leak and to make me spend more money.
Since my pump Works from 230 volts and since I didn’t want to take the chance of forgetting to switch the pump every time that I start the pc, I connected the pump directly to the psu through a relay. This way the pump is turned on automatically when the pc is turned on.
Since the radiator and the blower are way to big to fit in my case, I builded a separated case made of mdf, with a opening in one side in witch the radiator fits and to more openings in the top for the blower. The cold air from the outside is forced to enter the case (passing through the radiator fins) by the “vacuum” created by the blower as it pumps the air out of the case.
There are two more small holes in the case for the tubing that are sealed so the air can only enter the case by radiator opening.

Inside the mdf case I also have an old psu that powers the blower. This psu is turned on manually through a switch placed in the outside of the case. I didn’t installed a relay simply because even if I forget to turn on the blower the radiator has enough performance to keep the pc running without it overheating.

The blower is connected to the 5v psu rail and it makes almost no noise. I already tried 12v but the noise is too big for daily use and the difference in the cooling performance is almost zero. Even at 5v the air exiting the case makes may curtains move 2 meters away.

The CPU is an amd xp 2500+ Barton core (locked) overclocked to 2425 MHz (11 x 220) vcore 1.95v. in this configuration my temps are around 37ºC idle and 47ºC full load (temps reported by speedfan) ambient temps around 25ºC 30ºC
In terms of overclock I reached a Max of 2455 witch means 223 MHz fsb, I think I limited by my mobo (asus a7n8x-x rev. 2.0 - vcore mod and vdimm mod ) since even if I raise the vcore to 2.1v and the vdimm to 3.3v I can not reach 225 fsb. I didn’t tried the vdd mod since the soldering point is almost microscopic, maybe in one of this days …
