Testing Thermal Throttling in Pentium 4 CPUs with Northwood and Prescott cores Review

The issue of diminishing Pentium 4 CPU performance at overheating has
been widely discussed. Still, there are all sorts of myths about the
Thermal Monitor and Thermal Throttling technology. That is why we
decided to refresh our practical knowledge in this field (dropping the
theoretical aspect which is abundant in the above-mentioned articles).
For this purpose, we conducted a very simple experiment on two top
Pentium 4 3.2 GHz CPUs, one with a Northwood core and the other with a
Prescott. With the CPU loaded at 100 percent, we powered off the
cooler fan and watched the temperature rise and the performance
decrease as time went by. This article gives an account of the
experiment and its results.
