P4 Northwood 1.800A and 8IRXP temperature problem

[gsmciv]

I have setup a system using P4 1800A northwood and Gigabyte 8IRXP rev2.0 motherboard.

The processor was boxed and i'm using the retail heatsink. I think i have istalled it properly,
it wasn't that hard anyway.
However the temperature readings i get from bios Pc health menu
as well as from Gigabyte's SIV utility are very high and ranging from 45 degrees C when idle up to
73 degrees C when in processor full load.
I have upgraded the bios from version F3 to F4 and now
thanks to this forum to version F5. However the temperature readings have remained this high.
The cpu fan runs at about 2600rpm when the system is idle up to about 3200rpm when temperature
reaches 73 degrees.
The system is capable of running at that high a temperature for at least 3 minutes
(after that i shut the system down).
The case is a full tower with two extra fans which kept case temperature
on my previous P3 1GHz system at about 35 degrees C.
I would like to know if anyone else has similar experience or i have something, the motherboard
or the processor, malfunctioning. Could it be it just can't read the temperature correctly?

Please if anyone has any suggestions help me

I've got a 1.8A that I was running on the 8IRXP until last Teusday so I have some experience with it. I also used the retail HSF and thermal pad. The BIOS temps as well as Motherboard Monitor temps were low to mid 30's at Idle and low 40's at load (Prime95 for an hour or so) for the CPU. I got rid if that board (lots of issues with overclocking and NO support from Gigabyte) and got the ASUS P4B266. Temps with this board are low 40's at idle, high 40's at load. The temps generally read about 6-7 degrees higher than the Gigabyte temps.

I don't really know what to suggest, maybe try Motherboard Monitor and see what is says your temps are. It's usually works pretty good.

Might also try pulling your HSF off and look at the imprint of the thermal pad. See if it was making good, even contact with the heat spreader of the CPU. Remove the thermal tape (it's in 3 layers:black goo/silver foil/black goo) with acetone and a credit-card and use Arctic Silver on it. That should help your temps a little bit.
