[Cube] DO Powerlogix CPU upgrades run cooler? And how cool is cool?

[Steven Southerden Dive]

I'm running a PL 1.5GHz dual, which I've had a few months. It's  
showing 44C (110F) on the on-chip thermometer (CPU Director utility).  
Output air temp from the top vent is 30.6C (87F). Ambient is about  
19C (66F). Mail and Seti at home (BOINC) running all the time. Seti runs  
about one work unit per processor constantly, as long as it gets a  
new work unit when requested. Also have the nVidia MX2 32MB video  
card, which I installed several years ago, running the Apple Studio  
CRT display (the one with the transparent body) that I bought new  
from Apple in 2000 with the Cube. All working well, and never had  
more than minor problems. Cool as a cucumber (well, almost).

On the whole, this system seems as smooth running as my iMac G5 rev C  
1.9GHz.
