After placing the PPGA Celeron 366 in the MSI slotket's ZIF mount, we then locked down the Supercool 4500 fan/heatsink on the CPU itself. That's really all there is to it, the kit was now ready to be placed on a mainboard and run.
We installed the Net-N-Dude combo on three different mainboards to test for compatibility, the Abit BE6, the Soyo SY-6BA vIII, and the MSI-6163Pro. All three boards are slot-1 440BX mainboards, which support both voltage and other CPU controls via their BIOS systems.
All three boards booted up and ran while using the MSI slotket converter without a problem at 550MHz (5.5 x 100MHz). The slotket overrides the mainboard's native voltage level, and Net-N-Dude pre configures the slotket card to operate its CPU at 2.3 volts.
We were immediately impressed with the Supercool combo's ability to dissipate heat, its fan and heatsink have obviously been tested at length to provide superior results versus other options.
In fact, we compared the Supercool 4500's temperature reduction capability versus Intel's retail OEM PPGA fan/heatsink and found that the Net-N-Dude cooler lowered the CPU's temperature by up to 14 degrees Fahrenheit versus the Intel model. Not bad.
The Celeron CPU itself was clearly a strong one. Net-N-Dude does indeed pre-screen them for speed based on this particular model. None of our other standby Celeron 366 CPUs could achieve even close to 550MHz even when using the Supercool 4500 cooler.
Using the wide variety of FSB settings on the MSI MS-6163Pro mainboard, we even managed to stabilize the Net-N-Dude CPU at 578MHz (5.5 105MHz). It pounded through three hours of Prime95's CPU torture test in this configuration, along with some looping Quake2 Crusher demos as well.
