original pad measured , found approx 0.8mm, allowing compression during previous use, figured 1.0mm thickness suitable pad thickness new replacement. keen re-assemble imac didn't think take photo of new pad following change.
worked fine result, (as did before started), general refurb , internal cleaning - these g4 imacs need time time if in use regularly.

let me know if have doubts on exact location thermal paste (same on models refer to, different on earlier imac g4's). have photos if required.
