Bij Sharky Extreme hebben ze een review geplaatst van de dikke Net-N-Dude Glacier 4500 koeler voor de Pentium II en III. Dankzij dit model verkoopt Net-N-Dude nu ook P3-450's uitgerust met de Glacier 4500 die gegarandeerd de 675MHz (4.5 x 150MHz)zouden halen. Hieronder een gedeelte uit de review:
Well, our last in-house P3-450 didn't manage to replicate the results of the guaranteed models Net-N-Dude sells, likely due to its advanced age (manufactured in February) and the fact that it wasn't screened from hundreds of its siblings as Net-N-Dude must do to find those 675MHz diamonds in the rough.
We did see benefits from using the Glacier 4500 SECC2 cooler however, as it allowed us to overclock two of the three Pentium III CPUs to higher levels than their stock Intel-provided OEM units would allow. The newest Pentium III CPU we possess in-house, the P3-733, was not able to improve its max overclockable speed using the Glacier, it's also an early model in the scheme of Intel production 733 CPUs.
In terms of temperature reduction, the Glacier 4500 lowered the surface temperature of the chips we overclocked by approximately 7 to 10% in raw degrees Fahrenheit when idle.
In terms of peak heat production however, say when an overclocked CPU is getting 98 - 100% utilization continuously by an app (looping Quake2 demos, Prime95 number crunching) the Glacier kept temperatures up to 15% lower than the stock cooling units could, which indicates a strong ability to continuously dissipate heat.
