Unusually High Temperatures with p4 2.6C

[BestJinjo]

Hi i recently purchased p4 2.6C retail and Abit IS7 Motherboard.

At idle the CPU elevates at about 42-45*C, but when I run SETI@HOME the temperature jumps to 52-55*C!!!
Thats a 10*C increase at full load. Which sounds reasonable, but the original temperatures are too high it seems in the first place.

I used Arctic Silver 3, and I have an intake fan on the side helping to draw air for the main CPU cooler + a fan taking air from the top of the case right above the CPU retail again.. one intake fan on the front and exhaust fan on the back for a total of 5 fans in the case (if you include the CPU fan).

Did I apply too much arctic silver? or too little? is the retail heatsink so bad that it leaves me no room for overclocking when many websites easily take the 2.6C 800FSB to 3.2ghz with retail heatsink when mine runs already too hot at full load stock!!!

Is Abit IS7 motherboard not reading the temperature properly (I am using the Hardware Doctor that came with the CD from Abit) , problem with BIOS overinflating the temperature in the first place?

I have a thermal diode inside the case and it reads the air temperature inside the case of only 29.4*C

Please Help.

Abit boards are designed to show temperatures that appear to be higher than other boards. Check for other posts in these forums and in Abit's forums. All boards read the voltage from the diode in the P4, but then they each calculate it a certain way. Abit's is probably a more accurate temperature reading of the core itself, while others are probably a temperature that is more comparable to previous boards which used an external thermistor.

I'd bet if you got rid of a few of those fans (like the front intake and maybe the top exhaust) your temperatures wouldn't change a bit.
