As a part of testing the new big fans on the Athlon, I've run extended sessions of 3DMark2000, Unreal Tournament timedemo, and SETI. With SETI I consistently get 1 or 2 degrees Celsius lower CPU temperature than with either 3DMark2000 or UT. It looks to me like it's not exactly the most taxing test for an overclocked CPU.
