Question AIO cooler literally won't fit my pc

[ishaansphone]

I bought the CoolerMaster Seidon 240V as it's AM4 compatible, but upon arrival it seems to just not fit. The 'AM4' fitting method involves hooking the bracket onto a pre-existing mechanism on the mobo, which mine doesn't have.
The holes on the mobo are too far for any of the other brackets to reach, and there's no practical way of mounting the CPU cooler.
Mobo is GIGABYTE A320M-S2H

Your motherboard should have included those brackets in the box. Check your motherboard box, they are 2 seperate black brackets that screw on to those holes.

Get the manual at http://www.coolermaster.com/cooling/cpu-liquid-cooler/seidon-240v/ "J" picture shows right mount for AM4 socket. It doesn't mount on the holes like Intel does but on plastic bracket bolted thru those holes just like older AMD coolers used to.
