High-performance CPU Heat Sink Module

A high-end heat sink module for CPU is required if you use certain types of CPU. Even if you use a type of CPU
which is operable with a standard heat sink, you can reduce the electricity consumption of fan by using a
high-end heat sink module for CPU.
The electricity consumption of fan changes depending on the configuration of server and the workloads.It is
optimized in accordance with the amount of workloads, the density of configuration, the expansion of peripheral
configuration, etc.
For the list of CPUs supports high-performance CPU heat sink module, refer to the web site of NEC

Handling precautins

To prevent personal injury, electrical shock or equipment damage, unplug the power cord and ensure no power
is supplied to the server.
You cannot turn off the system power supply completely by the power button of the server. Until the AC power
cord is unplugged, the power supply circuit is still active in some parts of the machine.

Installation

Before installing a high-end heat sink module for CPU, prepare the followings.
 Parts included in the optional processor heat sink kit
 T-30 hexalobular driver

1/4-inch wide flat-blade screwdriver
To install the components, follow these steps.

Note In order to avoid the damage to the processor and the mother board, take care only
authorized persons change or install a processor.
Note In order to prevent the malfunctions of server and the damage to devices, use
processors with the same parts number if you adopt multiprocessor configuration.
Note If you intend to actuate a processor at faster speed, update the system ROM
before installing a processor.
