Did you lap the cooler too ?
did you lap it with the cpu in the socket ?
I taped some sand paper to my glass table in my living room and ran the chip up and down.
I lapped my heatsink as well but it's a push pin design crap heatsink so I wasn't able to lay it flat, I free-hand lapped that. I didn't care too much as I'm buying a NH-D14 soon.
It dropped my temps from ~85C max to ~75C max(Still running Prime95 from 30 minutes ago), so it's definitely effective.
I only get the 10C drop when I use the dot TIM apply method. When I smear it flat with my finger and a bag I get only about a 3C drop because the heatsink is either not laying flat on it or there's not enough pressure against the chip because it's push pin and not a screw system. When I take the heatsink off after smearing the TIM it's only contacting a rectangle in the middle of the chip. (This is actually why I decided to lap it.)
...and yes I know about the point of lapping, I just like the finish as a bonus.
When I get my Noctua I will smear a thin coat of TIM and mount the heatsink then take it off again to see the contact. If it's still doing that stupid rectangle thing in the center I will know it's the chip and I will re-lap it. (Pretty sure it's not the chip though.)Edit
