I was curious what kind of success all you AMD overclockers have had with the processors without serious cooling. I was bored and decided to try and get a bit more out of my Athalon XP 1800+ (1533mhz). After a lot of fiddiling I found that my main barrier was my memory (I was unable to use a 166 FSB or it was very unstable) so I ended up with a FSB of 152 and I have it running stable @ 1850 mhz with very basic cooling (cheapo heatsink and fan) and a small case fan. The only thing I find unacceptable at the moment is the CPU temp which is at 63 degrees celcius. I don't know what a "safe" cpu temp is, but I assume it should be less than 60 degrees celcius.
