What about Thermalright's V1 and V1 Ultra? I own both the V1 regular and the VF700 and here is what I got as far as temps:

Stock everything: Idle 47-50C Load 85-94C
Zalman VF700 @600/1230 Idle 40C Load 67-70C
Thermalright V1 (regular) @600/1230 Idle 37C Load <60C

After playing UT2004 for about 40 minutes the V1 did not even break 60C. Quite amazing. (By the way I used two fans on the V1 so that probably helped.)

Edit: I read about that mod on Anandtech Bull Dog. I really like what you did with that.
