The storm performed better stepped than unstepped 2-3c or so, but the apogee GT with the step is far better... the storm is just not good on an IHS'd CPU.

Any update ? Do you have new numbers to show us ? I'm interested to know what kind of improvements you got.
Would stepping also benefit an air-cooled heatsink like the Thermalright Ultra 120 extreme?
Theoretically yes. Stepping a block just allows for better contact between the IHS and the block.... that's it. So by theory, adding a step to any blocks surface should increase contact (assuming your IHS isn't screwed up) and give better thermal transfer.
and watch torque lift one side down because now that you have less area for a flat contact to help support it up. Or you can ghetto shoe lace brace it. :up:
waterblocks are much lighter then any high end air sink. Less weight = less torque = more even pressure on all 4 mounts.
Step vs Bow vs bad (convex) lapping job.. anyone? lol ;)
If stepping allows for more deflection of the IHS causing greater pressure and, therefore, lower temps, then would an extreme lapping (50% or more reduction) of the IHS result in even lower temps?
Any thoughts on the extreme lapping?
Yes, both actions are what I meant.
Now, how to step a Thermalright Ultra 120 extreme? Maybe secure a piece of metal, and leave only the area to be sanded down exposed? The piece of metal would act as a guide/shield. Then, use a dremel (would have to do this for all four sides).
Also, what dimensions for the step?
