Compatibility and related parts
Before buying, check that your case has at least 157 mm of CPU cooler clearance and that your processor uses an AM5, AM4 or LGA115x socket; you can compare processors (CPUs) and PC cases to match. Make sure you have thermal paste and pads on hand for mounting. The easiest way to confirm fit is our PC builder, which checks compatibility, and parts bought as part of a PC build get free assembly and testing.
