Notes and warnings Please note that the NH-U12S DX-4189 is a dedicated version for the Intel LGA4189 socket. Due to its customised larger base, it cannot be used on most other sockets and is incompatible with Noctua’s standard mounting kits.
The plastic CPU carrier frame supplied with the cooler is for LGA4189-4 (P4) only. LGA4189-5 (P5) systems use the same mounting mechanism systems but require a different CPU carrier frame. Please contact us at support@noctua.at if you would like to use the cooler on a LGA4189-5 (P5) type system.
