I Water Cool My Rig Too

Cooling/Water Cooling by SidneyWong @ 2004-04-02

Not all Water Cooling systems are created equal, the same applies to air cooling as we all know. A year or two ago, the bragging right was how loud your delta fan could run relative to how low the CPU temp was. Today, you?d better have water cooling just to keep a spot at any forum. W/C is in; Delta fan is out, at least for now.

Leak Testing & Results

Leak testing:

The scientific leak test … a clean rag.

These are the water blocks … I only use the CPU block for this exercise.

Time for a beer or two while I am awaiting the leak report… 30 minutes later I considered a success.

The crowded, unorganized close up of the back end of the pump; two decks below sits the first CD drive.

Houston! I have a problem. One of The Water Block mounting clips could not be installed due to interference of a capacitor.

The tap that allows the tip of screw driver to unleash was interfered by the capacitor on the (top) picture, cutting it solved the problem.


Now, time to reveal the system.

  • P4 2A C1 stepping
  • Overclocked to 3 GHz
  • MSI 6457 533/400
  • PC2100 2x256 1:1 ratio – meaning @ PC2400 speed (150Mhz)
  • ATI AIW oldie AGP 16 MB
  • 3Com Lan card
  • DVD CD
  • CD RW
  • IBM 80 GB HDD
  • Wire-trick default Vcore 1.7
  • Arctic Silver 5 – Courtesy from Arctic Silver
  • Windows XP Pro SP1

    The inside-look before Prime95 temp run.

    The actual fan RPM should have been half of what the chart says I did not adjust the divider from 80 to 92 mm.

    Disappointed? Not exactly, room temp was about 23C. But, I know the MSI board reports higher than actual temp by about 8C. The baby is now humming at about 45 dBA with about 35 dBA ambient still with one intake and one exhaust fans. Why? Because I still love my hard drive and care for the overclocked memory sticks. This is not any better than my 100% air cooling as far as CPU temp goes. The low volume pump from TOPSPEED was not designed for overclocking purpose. Therefore, I was not expecting a fantastic result.

    The Finished Good

    The same evening, I did some final cleaning-up. The wire-trick somehow got loose. The default voltage reverted back to 1.525 Volt surprisingly the system was running fine. It did not past Prime95 and so I increased it to 1.550 and here is what I got.

    Madshrimps (c)

    The load temp came down from 60C, so did the Vcore from 1.7 BIOS to 1.550. Could W/C attribute to the lower V-core? I have this board and processor over a year and I was never able to run it at 3 GHz with only 1.550 volt. I am going to install a temp probe with LED read out on the front panel (I know the BIOS temp is higher than actual by ~8 to 10C) which comes from the X-Dreamer case that I managed to destroy from HEAVY cutting.
