Are you using a Prescott 478 pin or a Prescott LGA775 processor?. My guess
is your using the latter, which runs a lot cooler than the LGA775 (3Ghz)
processor I'm using.
Intel's cooling solution and TIM appears to work well with Prescott 478 pin
processors, according to this article:
http://www.gamepc.com/labs/print_content.asp?id=prescottheat
However, on my LGA775 processor I found that it ran much hotter using
Intel's cooling solution:
Idle:
-----
CPU temp: 47C
Chassis temp: 34C
PSU temp: 42C
Hot (Test software: CPU Burn-in v1.0 by Michal Mienik):
----
CPU temp: 59C
Chassis temp: 35C
PSU temp: 54C
Oh and I should add that this was after I used the heatsink compound. With
Intel's TIM, add 10C to the above results!. Whether or not an exhaust fan
under the PSU, as per Intel's design guide, would have helped or not is
debatable since I have no room in my case to fit such a fan. Though I would
certainly recommend those with more modern cases to do so.
This article more or less sums up my views on the Intel heatsink. Also note
that the author appears to have been using a heatsink compound rather than a
TIM!:

It was only after I started using the Thermaltake Tower102. With two, 92mm,
2500RPM fans that I was finally able to reduce the CPU's temperature by a
further 6/7C:
Idle:
-----
CPU temp: 41C (down 6C)
Chassis temp: 32C (down 2C)
PSU temp: 41C (down 1C)
Hot:
----
CPU temp: 52C (down 7C)
Chassis temp: 35C (same)
PSU temp: 56C (up 2C)
And these temperature readings are in the same ball park as the temperatures
quoted here:
http://www.gamepc.com/labs/print_content.asp?id=prescottheat
And if your right about the fan under the PSU, then that should reduce the
CPU's temperature even more.
