NOCTUA NH-D9 DX-4189 4U
INSTALLATION MANUAL
Required mounting parts:
1x NM-XRF6
plastic CPU carrier frame for
LGA4189-4 (P4)
Installing the brackets1
When attaching the CPU carrier frame to the base of the heatsink,
turn the heatsink upside down so that the base is facing upwards.
Carefully put it down onto the tips of the heatpipes and secure
it with your hand so that it cannot tilt and that the fins cannot
get bent. Remove the plastic protection cover from the base of the
heatsink and be careful not to damage the layer of pre-applied
thermal compound.
Caution: If you are not using the heatsink for the first time and
it therefore doesn’t have a fresh layer of pre-applied thermal
compound anymore, you need to apply a thin layer of thermal
compound to the CPU yourself before clipping it to the heatsink.
If there are residual traces of previous thermal paste or thermal
pads on your CPU or on the heatsink, please clean them off first.
Assembly of carrier frame, CPU and heatsink &
installation to the socket

Caution: The supplied plastic CPU carrier frame is for LGA4189-4
(P4) only. LGA4189-5 (P5) systems use the same mounting
mechanism system 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.
Please follow the official Intel installation manual for how to
attach the CPU carrier frame to the heatsink, insert the CPU to the
carrier frame and install the CPU/heatsink assembly to the socket:
www.intel.com/processorinstall
Note that while the Intel illustrations show a 2U heatsink, the
Noctua NM-XFB8 brackets use the same mounting parts, so the
procedure is identical for Noctua heatsinks.
