What to know before buying

The manufacturer describes installation hardware for Intel and AMD platforms. Check that the included mounting parts match your motherboard socket.

Listing details to confirm

The listing has inconsistent detail: the title names AM4 and AM5, while the compatibility section lists AM4 but not AM5. Fan speed is given as both 1550 RPM and 1555 0 rpm ± 10%, and dimensional values conflict between 15.5L x 13.5W x 12.5H centimetres and 125 (L) x 135 (W) x 155 (H) mm. Confirm socket support, measurements and clearance for the specific build before buying. The listed 120 to 265 W TDP range is a claim, not an independent performance result.
