Compatibility notes

  • Thermalright states overall height but no RAM clearance, so check tall memory modules against the front fan position.
  • Overall height of 155 mm needs a case rated above that.

Common questions

Does the Peerless Assassin 120 SE support AM5 and LGA1851?

Thermalright lists AM4 and AM5 for AMD and LGA1700, LGA1200 and LGA1851 for Intel on the product page. The mounting hardware and guide cover those sockets.

How do I know if it fits my case and RAM?

Compare the maker's stated cooler height to your case's CPU cooler limit. Thermalright does not publish a RAM clearance figure, so measure tall memory against the fan position.
