AMD AM4 CPU Cooler Mounting Frame & Backplate Kit, Motherboard Heatsink Retention Bracket Base Back Plate for AM4 Socket Ryzen Processors

This complete AM4 CPU radiator mounting set consists of a front retention bracket frame and a thickened rear motherboard backplate, the essential replacement hardware for installing CPU coolers on AMD AM4 platform motherboards.

The backplate adopts sturdy metal plate with a built-in insulating protective film on the surface, which effectively avoids short-circuit risks caused by direct metal contact with the motherboard circuit, and greatly enhances structural rigidity to counteract the weight pressure of large heavy coolers, preventing PCB warping, socket deformation and CPU damage during long-term high-load operation.

It strictly follows the official AM4 mounting hole spacing of 90mm × 54mm, perfectly matches all mainstream AM4 motherboards equipped with Ryzen R3/R5/R7/R9 and Athlon series desktop processors. The locking clip structure on the upper bracket locks the cooler firmly in place, ensuring uniform downward pressure on the CPU core, optimizing thermal paste contact and improving overall heat dissipation efficiency for overclocking and intensive gaming workloads.

Widely applicable to various cooling solutions, including single/dual tower air coolers, 120mm/240mm/280mm all-in-one liquid water cooling radiators and low-profile slim down coolers. The installation process is straightforward: attach the backplate to the motherboard rear side first, fix the front plastic bracket, then lock the heatsink with matched screws without complicated modification.

It is an ideal spare replacement part when the original AM4 mounting kit gets lost, cracked or aged. Compatible with MSI, ASUS, Gigabyte, ASRock and all brand AM4 motherboards, a must-have accessory for PC builders, hardware enthusiasts and IT maintenance technicians.
