I got the 1400 stable at 1600. Today I added two 80mm case fans. I also added a bracket cooler with two 80mm case fans over the Geforce2MX.
Idle Temp: cpu-45*C chassis-29*C
Load temp: cpu-47*C chassis-29*C
AMD Athlon Thunderbird 1400mhz @ 1600mhz, 1.85V
Full tower case
400W power supply
Six 80mm Case Fans (two in bracket)
Four fan Hard Drive Cooler
OCZ Goliath heatsink/fan
CPU shim
Artic silver 2
I will probably be adding three 120mm case fans soon. Then I will see if I can get it to be stable at 1666mhz
