185ºF? Yow! That's 85ºC! Either G5s run hot and aren't cooled well or you've got your computer in a drawer or something... Even my AlthonXP rigs rarely run over 60ºC (140ºF) when folding 24/7 in a warm room...
Regardless, it's nice to meet a fellow folder in these forums, I should direct you to the largest thread in the forum (correct me if I'm wrong guys),
Got any spare CPU cycles, buddy? where there's always something going on...
