by putting a penny under the bracket, it increases the resistance and decreases temps.
Pennies may be too brittle/malleable, though. They tend to dent from the pressure. If you can get ahold of a strong washer, use that instead.
As a previous poster said, the fan that you are using may not have enough static pressure. Static pressure is the ability for a fan to move air through tight places, and since the TRUE has a very dense fin structure, you need a fan with a lot of static pressure.
When you lapped, did you make a mirror finish of copper, or the aluminum? Basically, did you lap it until it was a flat, copper surface, or did you lap until it was just shiny. My first time lapping I just sanded until the IHS and HSF were simply just a smooth aluminum surface, I didn't go far enough.

The day I believe that... Funny how you expect us to believe one fan in a push-pull configuration takes 10C off your idle temps.
