Chickala and Prelude, I don't know what to say. I have an non-overclocked Athlon XP 1900+ and it never gets above 50 C, not even after 24 hours of running the Anthrax screensaver (100% CPU load) from United Devices. I'm only using aircooling from a front and rear fan and a Coolermaster HSF, the EP5-6i11, which was $7 from http://www.newegg.com
. I've heard the Tt Volcano 6 is pretty good-it has a cylindrical copper core that connects to the processor die and is surrounded by the aluminum HS fins. That one runs about $13.
Sometimes, adding too much Artic Silver paste will cause the CPU to run hotter than it would without it. That might be a problem, too.
Normally, I would be itching to overclock this XP 1900+, but I'm looking to just get another one to match it in an SMP system in a few months and don't want to take years off it's lifetime expectancy for no really good reason.
If your CPUs are running that hot without overclocking, something is wrong. The XP's, as they get higher in rated clockspeed from the factory are supposed to be running gradually cooler than the Thunderbirds, especially the 1.4 GHz, which is the hottest one.
I wouldn't even be attempting what some of you guys are managing to pull off without water cooling or even liquid N2.
