CAFELE AM4 CPU Cooler Backplane Bracket 90x54mm Black White

AM4 Backplane Bracket 90×54 mm

This copper and ABS mounting plate replaces the original heatsink back-plate on AMD Socket AM4 motherboards. It provides a rigid base so the CPU cooler cannot flex the PCB under clamping force. The part is sold alone; no fan or screws are included in the package. Builders upgrading an older board or assembling a new AM4 system use it when the factory bracket is missing or damaged.

Mounting hole spacing 90 mm by 54 mm

The plate only fits boards drilled to the 90×54 mm pattern used on AM4 chipsets such as B350, X370, A320 and X470. Boards with different hole spacing cannot accept this bracket, so the cooler will not mount. No other socket or form factor is supported by this specific hole layout. Verify the motherboard manual before purchase to avoid a mismatch.

Copper core with ABS frame

The copper centre spreads heat away from the mounting posts while the ABS surround insulates electrically and resists warping over thermal cycles. Two colour choices — black or white — let the bracket blend with different board aesthetics. A small alignment pin hole on each corner matches the motherboard locating pins, ensuring the plate seats squarely every installation.
