I have a dual system with 2xP3 866 MHz processors. They currently hover around 40C/102F while under 100% load (RC5). Got Golden Orbs on them. What I am wondering is this typical? Hotter/colder than average? At what point do heat become a factor with these processors? I currently only have a front case fan and the PSU fan. Should I make the investment and put in another 80mm fan directly under the PSU? I have some 92mm fans but it would require drilling new mouting holes. Suggestions?
