Well having a feeling that it was a refurb. I bought it on ebay. Didnt come with the backplate or the retention bracket. I checked our thermalright and they have both but they are sold seperately and the bracket is for one of their heatsinks, so it may need modification to work with the OEM heatsink.
Oh and it was MSI
On a side note, do you guys maybe know of a cheap aftermarket heatsink that requires you to remove the OEM retention bracket and backplate? Thinking I can just buy that. Thanks.
