All CPU's are different, so giving an average is difficult, but for some scale, here goes:
Newer CPU's and mobo's have an auto-shutdown feature at somewhere around 80 C, because any hotter and permanent CPU damage can be done. The new AMD 64 Winchesters run very cool. Right now I have an AMD Athlon XP 2500+ that runs idle at around 40 C and load at around 45 C. 61 C is getting pretty high, and I would look for a way to cool that down somehow probably.
rcsavageboy, being a dell, I bet you won't be able to put your FSB any higher...tough luck.
