Well, that's a warning for the service engineer about the large heatsink in the middle of the PSU, not the capacitors which are standard parts and have nothing to do with any heatsink. Obviously (if anywhere) they had to stick the label somewhere where it would be clearly visible, would not obstruct heat dissipation and would not risk the label itself crumbling with time under heat (so not on the heatsink itself). Obviously you'll do whatever you wish, it's your PSU after all. :) Maciej
