I plan on using my XP-90.
I just read Maximum PC's yearly Dream Machine article and it speaks volumes for conroe's low heat output. They used a Core 2 Extreme x6800 stock at 2.93 in their rig with a Zalman CNPS9500-LED to demonstrate the chip's cool nature. Using Nero recode to load both cores at %100 they notice only 3 degrees difference between idle and full load temperatures. They even went as far as unplugging the heatsink's fan and continued to run at full load for hours! :Q Holy Smoke, would you try this on your $1100 chip? After reading this I am sure my XP-90 is up to the task.
