"Supposedly" the Volcano 2 should work, but for peace of mind, I'd get something better (such as Volcano 5/6/7). "Something better" wouldn't cost very much. The Volcano 2 will work according to Thermaltake and if you examine the actual HSF that comes in the retail box for an Athlon 1.4, you'd find a heatsink IDENTICAL to the Volcano 2, except for a SMALLER 60x60x10mm fan.
