@Cathar: No need to say it like that. And maybe some people do that because thei rads are inside their cases (not my case).
@everyone:
In fact, I should have measured the radiator air intake temp and the water temp and at the reservoir before turning the rig on instead of case temp, my mistake, tonight I'll post the new numbers and a test of another version of the block I have here.
You wanted detail, I'll give you even what you didn't want to know
PC specs:
AMD Athlon XP 1700+ at stock speed and Vcore
Soyo Dragon +
256mb DDR
2x Samsung 40GB 5200RPM in RAID mode 0
Geforce 2 MX 400 w/ TV out
Pixelview TV/video capture card
LG DVD ROM 16x
Samsung CD-R 8x4x32
Water cooling system specs:
Atman 1200 pump
Aluminium radiator with parallel flat tubing (not in the market)
2x 120mm 220V fans
1/2 tubing
pump - block - rad config
Here are some pics of the test rig, I didn't want to take those because the block I'm using has absolutely no finish so it looks very bad. Of course the ones for sale won't look anything like this. Also the soldering (for the hose fittings) is ugly because I was experimenting a new soldering method on this one.
Before you ask, the black box in the rad is the fan's speed control so I can make it silent when I'm going to sleep with the PC on or watch a DVD.
Thanks
Bruno
