DIY CPU water cooler

[Gary]

brings back memories, i used to overclock my PC's when i was younger, and had full water cooling to keep the noise down.
May be better to make it out of copper and also lap the underside to get it as flat and smooth as possible.

I have Intel Core2 6400, 2.13 GHz LGA775 Socket. Heatsink is original Intel supplied together with CPU. It's wholly aluminium. When running with few aps on average CPU temp is about 50C. After light 400 grit wet sanding a contact surface I would risk to say is more smooth than original heatsink.

Pics below shows a heat exchanger mount cut out from 3mm stell.

There is some more pictures & details of this project at my website:

Finally a clear pipe arrived today. I decided to try gravity circulating cooling system before I start to mess with any pump. At the moment of writing this a computer is on for more than an hour. Temperature of CPU is 33C. CPU usage is about the same like last time picture. So for now full success :dance:.
