Heatsink

The AM5 socket specifies the 4 holes for fastening the heatsink to the motherboard to be placed in the corners of a rectangle with a lateral length of 54×90 mm, as well as UNC #6-32 screw threads for the backplate, identical to those of the preceding AM4 socket. Furthermore, the Z-height of the CPU package is kept the same as that of AM4, for backward compatibility of heatsinks. Unlike AM4, the backplate on AM5 is not removable, as it also serves the purpose of securing the CPU retention mechanism for the LGA socket. Not all existing CPU coolers from AM4 are compatible. In particular, coolers that use their own backplate mounting hardware, instead of the default motherboard-provided backplate, will not work. Some cooler manufacturers are offering upgrade kits to allow incompatible older coolers to be used on AM5.
