What's the point of the retention bracket on the bottom of the mobo?

[darksparten]

My Corsair H60 came with a bracket that was supposed to mount on the bottom of the motherboard, I put it in, and mounted the rest, but the bottom mounted bracket fell off, but the cooler is still secure.

What's the purpose of the Bracket?

you didn't install it properly otherwise it's supposed to hold the entire cooling unit/chamber onto your mobo - and to answer your first question, the use of the bracket is to add support to the back of the mobo seeing how a cpu can cause a PCB to flex and usually result in an improper seating, leaving a slight bow, affecting temps negatively. The back plate gives a more even seating on the cpu contact patch.

The 4 screws around the H60 block should screw into the bracket I believe...

You're doing it wrong.
