Which consoles need new thermal paste/pads?

It's 2016, which consoles should the thermal pads and paste be replaced on?

 

ps3 and xbox 360?
maby the orginal xbox?

Those are really the only ones I could think of.

 

Not sure if anything should be done to a Wii (& U). Your Dreamcast might want some new pads tho.

If you want to go overboard you could paste up the Gamecube & maybe even N64, despite them not having any from the factory... Might make them .5° cooler after those 18h play sessions. And if you're that anal or bored, you'll also want to do all your current gen stuff because the stock paste isn't exactly top of the line.
