Tigerbiten,
Have you considered instaed of running windows and 2 linux O/S's on one machine you could just run 1 linux OS with 2 instances of SMP (from different folders). You lose the overhead of windows and 1 linux O/S. Its faster to boot and is a lower memory hog. You can start the SMP with...
While this is strictly legal this contest is designed (as are all of them) to get and keep the interest in folding. We should not (in the name of science) halt or store partly done WU's to jumpstart the score for the sake of a contest.
The amount of heat generated by a computer is directly related to it power consumed. Each watt consumed is equal to 3.3BTU, So a quad using 175W is producing (175W x 3.3) 577BTU of extra heat into the room. A standard room (144sqft) with 3 computers running can be cooled easly with a 7500BTU...
The better question is what MB did you put it in. B3's will go 3.2+ on an P35 board (GA-P35-DS3L) but I found a lot of P965 chips that will not O/C well with a quad
I have three quads all right next to each other with ultra 120's cooling them. All are clocked at 3.4 ghz and stay at 48deg with silverstone fans. They are in a basement office (very quiet) running F@H and I can barely hear any fans running.
I have a similar folding machine and it draws 135W (it does have a harddrive and an x300 video card though so mine should be highr than yours by ~10w). A 250W supply will be fine
