I have a Pentium III 450 CPU running at normal speeds (not overclock). My motherboard is a ABIT BE-6. The CPU reaches 29 degress C rather quickly and it stays there (with CPUIdle enabled). Without CPUIdle, the temperature goes up to 31 degrees celsius.
Is it normal to have a P3 450 running at 29 degrees C? Or should I replace the fan or get better cooling in the case? (keep in mind I didn't overclock it and is using the fan that came with the P3.
Any thoughts on what the normal temperature should be?

If 29°C is at idle, try getting the temps at full load. Running multiple zip/unzip files/Q3/UT/SETI/Prime 95 to get 100% usage and for about 30 mins and get the temps at load. My guess is that they should be about 36-37°C and while that's slightly warm, that's well within normal/safe limits for a Katmai processor. Consider adding a second or third case fan to your case and tie down ribbon IDE cables to the side of the case to improve airflow.
-=S_Klass=- I tweak... therefore I am.
The Katmai core PIIIs are up to 500MHz and run a 100MHz FSB only and come in Slot One formats only. They also have 512kb of off-die cache that runs at 1/2 clock speed. The Coppermine core PIIIs are from 500MHz up to 1GHz and come in FCPGA (Flip Chip) as well as Slot One formats and run at either 100MHz FSB (designated E) or at 133MHz FSB (designated EB). They have 256kb of on-die that runs at full clock speed.
Dude, 29C is a nice temp! I set my friend up with a Katmai PIII450@560 and its temp idle is 31C and gets up to about 44C playing games like UT and QIIIA (He keeps his freakin' apartment hotter than HELL)! And with temps in the mid forties his system is ROCK stable. Intel rates the Katmai's MAX temp at 90C (you'll start having problems at around 60C though). So your temps are fine, don't worry about them.
A slight correction as the Katmai's went to 600mhz, and if you get a good 450mhz they will o/c to at least 600mhz with a good heatsink (Alpha) some get 650mhz or higher with active cooling. I have a 450 here at 600mhz 26 to 29C (using the Win 98 MSidle) and around 42 max under load. SL35D or SL37C were known to be particulary good versions and all you should require, (other than the heatsink) is ram that will run at 133mhz and a graphics card happy at 89mhz (voodoo 3, Geforce) if you have a 2/3 max AGP divider, some newer 133mhz chipset mobos have a 1/2 AGP so you can run everything in spec and just o/c the CPU.
Try putting your HDD on the normal motherboard connector and rerun that test and you should see a slight improvement. You thought your test was bad, when I had my UATA/66 card in it gave me 2.1Mb/sec. When I connected it to the motherboard, it gave me 19.4Mb/sec. I don't know what it was, but it worked for me when I used the onboard controller.
