I'm sorry....
I never gave that much thought on that.
Stock for Stock, AMD boxed coolers are much harder to operate for the novice but the Intel ones keep breaking/falling apart after some time to the point the cooler is no longer useful and then you need a new one or an aftermarket one.
If you mean aftermarket brackets, I'm sorry, doesn't seem much of a difference to me.
Care to elaborate, maybe?
