Been getting into the folding @ home project at Stanford lately (Wiki info here). Running a little bit of the spare CPU cycles available on the 3 computers at home that run 24/7.
The way I have set them up they churn out work units for the folding project without making the machines run hot. Had to pull back on the CPU cores it uses per default though, made all the machines run with their fans on constantly.
Anyone else contributing to these kinds of projects? Would be interested in what else is out there, as well as where I can find discussions on the folding @ home project. Wondering if I can easily get the GPUs on my Mac computers to be a part of the "home farm" as well.
