My definition of 'hot' is 40C or more. Take an Athlon XP/MP 2400+ at 1.50v for example. With the retail heatsink/fan it runs slightly above room temperature at full load. I'm testing some for enrico right now as a matter of fact, and full load with the SK7 and an 80mm fan running 40cfm (nearly silent) and the CPU temperature is 25C w/ 21C ambient air temp. The same setup with a 2.25GHz Athlon 2800+ runs about 32C. My water-cooled Athlon XP 2100+ (1.73GHz) at 2.5GHz runs about 30C as well. If you consider this "hot" I'm curious what you call a P4 normally running 60C. ;) As I mentioned before. With decent case cooling, a quality copper heatsink and a 40cfm or more fan (you can find nearly silent stealth fans everywhere) your Athlon chip won't even come close to being hot. Also, don't forget Arctic Silver 3 compound. The thermal pad crap is completely worthless and will guarantee your temps are 10C higher than without them. Remove these with lighter fluid, clean them well and put arctic silver 3 on the core. As for a P4... look forward to screaming fans & expensive heatsinks to keep your cpu temps reasonable.
