These are the initial results before taking into account the ambient temperature. The Gigabyte 3Dcooler-ultra PCU31-VH appears to perform a little better on the socket 478 Pentium 4 platform than the k7 test platform which is interesting. This is no doubt due to the increased surface area in contact with the copper base for the Pentium 4.

Before we get to the final rise above ambient test results for the Pentium 4 platform we're next going to see how the 3DCooler-ultra performed on the synthetic AthlonXP temperature test platform. The preliminary results for that set of tests are not shown above.
