EKWB AM4 mounting plate (black) Versus AM3 mounting plate (silver).

 

 

 

I think we will be able to mod out AM3 brackets rather easily.... interesting proposition.

I was already planning on modding the mounting plate for my Apogee XL, I just hope the threading is the same for the AM4 stock backplate as I need to reuse screws that fit the AM3 stock backplate.

 

Just 3mm in vertically and 3mm out horizontally for each screw

even though it's a new socket they have ensured the cooler mounting mechanism is compatible

But that is only for coolers that use the clip mechanism. Coolers that screw into the backplate need new hardware.

Just to clarify to keep people from getting confused.

Well neat if so
May just reuse AiO then

That's because EK made it specifically to be retrocompatible with the elongated screw holes. The mounting is a little different on the socket itself and more importantly, the AM3 block probably can't mount onto the AM4 platform. But yes, you can most certainly mod it - if you have a power drill that can extend those holes without destroying them. In the end most people will probably be better off buying a new mounting bracket if they want to carry over their block, which sucks because those things are waaaay more expensive on their own than they have any right to be.

Doesn't some companies give them to you for free? (Heard of that with Noctua)

Yes, but that's down to the company.

$14 for the bracket isn't too bad.

ncix price

 

From Wan show it almost seems like they are saying am3 holes are compatible with am4, not new bracket is good for am3 and am4.  Either they are confusing or confused.
