The Bracket that came with my cpu water cooler , and the pegs just move like 1/4 - 1/2 an inch.
Results on google say its supposed to be loose a little bit??? but not that much??
I'm wondering if the Instructions for the Pegs are wrong? and supposed to use shorter pegs to make the Bracket & Pegs more snug/tight to the mobo?

Nevermind Its supposed to be 3MM wiggle room, the water cooler is a reversed spring Tension type .

What gpu you pairing with that 11700K?

Yeah turns out, its supposed to be loose, once you actually start tightening the Water Cooler Unit itself, it gets very firm/tight, because it actually Pulls on the pegs anyways.
