 Review, CoolComputers Tri-Arc Watercooler
The performance test
By: Sverre Sjøthun, May 2, 2002  Print this article

o

Performance if one of the main reasons why one would invest in a watercooler, and most that consider this as an option are overclocking their systems as well, so we will poll temperatures at various CPU frequencies and voltages to show you how this cooler perform in a real life environment.

The testbed

- AMD Thunderbird 1.4GHz AYHJA stepping
- Abit KG7 RAID
- 2x256MB Crucial 2100DDR, none parity
- 2xIBM 60GXP, RAID0 (disk striping)
- Elsa Gladiac GTS2
- TSP 520W triple-fan powersupply
- Windows XP Pro operating system

We will during this test look at idle and full load temperatures at different speeds. The first temperature is measured at default speed and voltage. To see the coolers scalability, we increase the multiplier by 1 up to where the system no longer is stable at default FSB (133/266). This is to make sure that all other components but the CPU is running at their default specifications. After that, we also show you the maximum speed with both multiplier and FSB tweaked. The core voltage is set to 1.85V except at default speed.

Genome@home has been used to stress the processor. If the Processor is stable at 100% load after one hour of Genome@home, the temperature has been polled.

Looking at the chart above, you can see how well the cooler perform at different speeds. At default speed and voltage, the temperature is 12 degrees above ambient temperature at idle and rises to 16 degrees above ambient at full load. The maximum speed attained with this cooler was 1644MHz with the core voltage set to 1.85V, FSB to 137MHz(274) and multiplier set to 12.

All temperatures Celsius

All temperatures Celsius


The chart above show you all temperatures measured in Celcius. We managed to boot into WindowsXP at 1668MHz, but hang the same second we tried to do something. We managed to use the computer at 1656MHz for a few hours doing normal office applications, playing WinAmp et cetra, giving a 10-20% CPU load. But once we fired up Genome@Home it only took 10 minutes before the OS was not responding.
