We wanted to push the processor to its thermal and performance limits, so we picked Prime95 as our primary stress tool.
Prime95, version 23.8.1, under Windows XP Professional using Service Pack 2.
This option seems to be made for our purpose.
For measuring the temperature of Intel's zone 1 and 2 we used Chipzilla's Active Monitor, version 188.8.131.52.
Each specified temperature maximum is provided on the Intel Website under Thermal Zone Information. Of course we used the numbers provided for reference.
Next, we also wanted to monitor what the CPU did. For this job we used a non public utility that displays continuously the core clock speed and shows if a CPU throttles.
- The Heat Can Cause Intel's P4 To Throttle And Damage Over Time
- The First Step: Buying The Processor
- Intel's Specs Say The Chassis Temperature Max. Is 38°
- Step Two: System Setup
- Software Used
- Measurement One: Intel Boxed Cooler And Original Thermal Pad
- Measurement Two: An Intel Boxed Cooler And A Standard Thermal Compound
