I have always cleaned and re-applied heat sink paste to ICU's when I have them off for whatever reason. (Almost always for something other than replacing the ICU.) Regularly re-applying heat sink paste as scheduled maintenance? I have been around SO many ICU's that never had that done including my own that I find it hard to believe it would make any difference. Fixing a bad ICU with heat paste? I haven't seen that many ICU's go bad but heat sink paste wasn't the issue with bad ICU's I have found.
