Finally!!!

Yeah people, after about two years (since June 2001) my watercooled PC-70 is finally operational (in test phase anyway)...
I already told it several times, but my own company, KD Computing Services, takes most of my time...

I'm quite satisfied with the results for the moment, taken into account the age of most of the parts (radiator, WB, mobo...):
Asus A7V333 Raid with XP2400, softly overclocked to 2250MHz@standard 1,65V and 1GB of PC2700 DDR (although I could reach easily [email protected] on aircooling with this CPU).

Still lots of finishing work to do but I can see some progress...

As usual, some pics:

Mounting of the Danger Den GF4 block on my MSI Ti4400.
As usual everything in hardsoldered 15mm copper tubing.









PS: All pics are hosted on my Skynet webspace for the moment, we are migrating our IIS-server at KDCS to Linux-Apache, and I don't have FTP access from home for the moment... (www.turbokeu.com is hosted on the webserver of the company)

15mm copper inlet and outlet on my Maze3 WB (the long outlet has been modified afterwards with pieces of Tygon tubing to prevent torsion from the Maze3 onto the CPU).




Connections between WB's and copper tubing are sealed with this product:

Settings of the XP2400 (1st week 2003 AIUHB).


Motherboard Monitor Dashboard Idle (Ambient temp=25.5°C and Panaflo M1A radiatorfan at 6.5V)


Idem 100% CPUload with Prime95 after half an hour.

Difference between radiatorfan at 6.5V or 12V is merely 1°C...
Watertemp is measured with 10K NTC in my airtrap (and connected to mobo) and fishtank termometer for calibration.

Overview: Please note that finishing isn't done yet.
I have blue dye lite from Becooling but I ran the tests with the rest of my old coolant mixture with green dye lite + Purple Ice.


Airtrap with 10K NTC resistor in waterflow for tempmeasuring of coolant (upper arrow) and cable to JTPWR-connector on mobo (lower arrow), and fishtank termometer in the coolant.


Lower arrow indicates my Swissflow SF-800 digital flowsensor connected to the outlet of the Eheim 1250.
Upper arrow indicates the cable with the output signal to my digital flowmeter cicuit.

I bought some (25 pieces) blue rectangular leds in the US...


To replace the red leds of my radiator fanregulator and voltage monitor.

After:


Meanwhile I connected also my Seetron SGX-120L grafical LCD...

And the digital Swissflow flowsensor too...
Waterflow is 4.39 liter per minute (variates between 4.39 and 4.41 liter/min).
Seems a little low to me, but is probably caused by the flow restriction of the cube-style radiator, and the flowsensor itself whose ID is 8mm (the rest of the circuit has an ID of minimal 10mm and the total length of 1/2" Tygon tubing is less than 1.20m (four inches)).
I still have to set the CPU speed indicator to the right speed (actually 2250MHz)


Overview of the electronics:
Digital flowmeter on the left, CPU indicator on the right, on the lower right the Seetron LCD, and on the left of it (not visible) my radiator fanregulator and voltage monitor.

Do not pay attention to the cabling spaghetti, has still to be finished...

looking nice and clean so far.
