My setup now after the CPU lapping is a lapped Thermalright Ultra 120 Extreme that I just bought prior to lapping the CPU. My old setup (Zalman HS and unlapped CPU) resulted in temps around 67C on a 2.70GHz overclock at full load. Now my current setup (lapped CPU and lapped Ultra 120 Exteme) results in 54C at the same overclock on load. Pretty sweet! Both before/after were with Arctic Silver 5 thermal compound.
