Manufacturer description
The DGZZI AM4 Backplane is a replacement CPU heatsink mounting plate for AMD Socket AM4 motherboards — the part you need when the original backplate is missing, cracked, or was left behind in a previous build. Built from copper and ABS plastic, it resists the flex and deformation that can cause uneven cooler contact, and the copper body helps pull heat away from the socket area so your CPU keeps running at expected temperatures. The mounting hole spacing is 90x54mm (3.54 x 2.13 inches), matching standard AM4 layouts on B350, X370, A320, and X470 chipset boards. Small locating holes on the…

Frequently Asked Questions
Will this fit my AM4 motherboard?
It is designed for AMD Socket AM4 boards with 90x54mm mounting hole spacing, and DGZZI lists AM4 B350, X370, A320, and X470 chipsets as applicable. Measure your board's hole spacing before ordering.
Does this include a CPU fan or heatsink?
No. The package includes 1 AM4 backplane only. It is the rear mounting plate that cooler hardware screws into — you supply the fan or heatsink separately.
What is it made of?
Copper and ABS plastic. DGZZI cites the copper for heat dissipation and the construction for resisting deformation over a long service life.
Do I have to take the motherboard out to install it?
Yes, in most cases. The backplane sits on the rear of the board behind the CPU socket, so you will need to remove the motherboard from the case to swap it.
