Ok I have a 2.0GHz PM G5 that gives off an aweful high pitch sound when running games (UT 2003 and WoW). The system is quite as a mouse the rest of the time but loud in games. Now, I ran folding@home using the InCrease pluggin and setting a protien to run on CPU 2. I have a few questions... If the app is taxing CPU 2 then why does CPU 1's temp go up too. The procs used to run at 136 and 134 and now they run at 158 and 155 with folding. Is this bad? Will this shorten the life of the computer by doing this? Second, does folding know to back off the CPU if it needs to be utilized for something else? I did a flyby benchmark in UT 2003 and got the following results.. 30.887060 / 83.967232 / 249.375061 fps -- Score = 73.866318 w/folding on 33.947971 / 84.106590 / 225.305328 fps -- Score = 74.008659 w/ folding off As you can see, it made bascially no noticable difference in the game performance and made the computer shutup haha. If a game was to use the second CPU from time to time as WoW sometimes does for sound will folding hurt me? Any information on this would be great. Thanks!
