We produced the highest possible temperature using the OCCT v2.0.1 software with a custom 30mins (mixed) operation:
We left both cores of our Intel Core i7-920 running at full load for ~30 minutes. The temperatures were logged using the CoreTemp 0.99.3 and the software itself. We took two measurements with our CPU running at stock speed and with then under overclocking:
The sound measurements were logged using the Precision
Gold N09AQ Environment Meter. All the measurements were taken at a 30cm distance from the cpu cooler, with its fan spinning at full speed. For all the coolers appearing in the comparison charts we used the thermal
compound, the Tuniq TX-2. As a last note, we remind you that these measurements may slightly differ from any possible measurements you may have, even if you are using the same testing configuration.
