Threadripper TR4 and TRX40 Mounting Bracket

This Alphacool bracket (model 12875) provides the hardware needed to secure compatible water blocks onto AMD Threadripper processors using the TR4 or TRX40 socket platform. It replaces lost or damaged mounting parts for existing cooling assemblies. The kit includes the specific brackets and fasteners required for these large-socket CPUs.

Suits owners of listed Alphacool

Builders using an Alphacool Eisbaer AIO, an Alphacool XPX Eisblock, or a Be Quiet Silent Loop AIO can install this bracket to support Threadripper TR4 and TRX40 sockets. It is not for users of other cooler brands or models that do not share this mounting pattern. It also does not fit Threadripper sockets other than TR4 and TRX40.

Mounting compatibility decides fit

The single specification that determines whether this part works is the cooler model you already own. Only the Alphacool Eisbaer family, the Alphacool XPX Eisblock, and the Be Quiet Silent Loop family are confirmed compatible. If your cooler is not one of these, this bracket will not mount it.

Questions about this item

How is the 12875 bracket installed on a Threadripper cooler, and what step is often missed?

Remove the original mounting frame, align the new bracket with the TR4/TRX40 cold-plate holes, and torque the captive screws in a cross pattern; the step often missed is reusing the original back-plate instead of the one supplied with the bracket.

What part of the 12875 kit will need replacement after repeated cooler swaps?

The captive mounting screws and their shoulder washers can strip or lose spring tension after several installations, so keep a spare screw set for future rebuilds.

What mechanical limit appears first when the 12875 bracket is used under sustained heavy loads?

The bracket itself has no moving parts; the practical limit is the cooler’s cold-plate bowing or pump degradation, not the mounting hardware.
