Hi: I have two MDD's with dual 1,25 ghz cpus that I run CHUD 3.5.2 on. The CHUD tools give the option of running single or dual cpus in "nap" mode. I run mine in single cpu mode with no discernible loss in processor speed/capacity. I also read that dual cpus in nap mode can cause crashes, but I've read no complaints of crashes with the single cpu. Most of the "literature" suggests single cpu use.
The cooling and noise reduction are satisfying. On this warm morning the MDD is running at 98 degree (F) in single cpu. If I kick into dual non-nap mode it'll go up to 138 degrees (F) and start that wind-tunnel fan effect that MDDs are known for. CHUD seems to work best with Tiger. I've tried it with Leopard but there seem to be problems with keeping the cpus in single mode. I have up to 6 or 7 people using these machines on the internet and they've been stable with the CHUD tools for a good period of time. Good luck with whatever you decide.
