My water cooling unit do sit seem to fit

[Jason McFarland]

So I got a sedion 120m water cooling unit for my A68HMK but It doesn't seem to fit. The box says am3 and am2 which I have an am3. Did I still buy the wrong one?

Doesn't seem to fit* sorry for the grammar.

are you using the correct Mount/backplate?
