For good and sufficient reasons, I want to swap the coolers on two motherboards. (One is LGA1155, the other LGA1150; there should be no compatibility issue.)

If I do this according to the Boy Scout manual, I'll remove both coolers, clean both coolers' thermal plates, clean both CPUs, put new thermal paste on both CPUs, and reinstall.

If I do it the quick and easy way, I'll clean nothing, put a tiny bit of extra thermal paste on each CPU, and reinstall.

I know the quick and easy way is wrong, but how wrong? Is it an obvious shortcut that won't cause any problems if I do it right, or is it a really bad idea that will get me in trouble for some reason that I'm too dumb to see?

Since the votes are 2:1 against so far, I'm inclining toward the Boy Scout method.

A couple of details, in case they change anyone's mind: both paste appllcations are fairly new (<small number of months) and they use the same kind of paste.
