I have a generic HSF that fits standard Athlon sockets and uses an 8CM fan. After lapping it for about three hours and finally using 600 grit paper, my temps were 7 degrees cooler at full load.
8 CM Y.S. Tech 60 CFM
A7V266-E
Locked AMD XP-1700 @ 1.80 V - 1540 MHZ
Before: 54 Deg.
After: 47 Deg.
I then clocked it higher.
XP-1700 @ 1.85V - 1610 MHz - 53 Deg @ full load - Stable.
Still running hot, but to this day I still do not trust ASUS temps
