I actually did this mod for all of my S1s and saw a 1GH inprovement across each unit. I have enough for one unit coming in on Monday so I'll go ahead and try it myself to verify.
The part you are looking for are the eight grey square "blocks" above the heat sink. There were only four-per-blade on the S1

The layout of the S3 board seems to allow for a single long heat sink to cover all of the dc-dc converters? The S1 layout had caps in between preventing the use of a single large heat sink. I bet the larger surface area will work much better than the smaller individual heat sinks.
Anyone know where to find something that will fit, and how to properly attach?
