Server tour: Heatsink, CPU and fans


A pair of metal levers (one of which is obscured by the fan baffle in
this image) retain the heatsink in its place on top of the CPU.

The notches on the bottom of the heatsink are there to ensure
that it is installed with the correct orientation. You can also see the
copper heatpipes within the heatsink in this image. The Intel Xeon
processors used in this server utilise a Socket J CPU interface
featuring 771 pins similar to the 775-ping Socket Tinterface used on
desktop systems.

To remove or install a CPU the lever must first be unlocked and raised and then the CPU retention cover must be raised.

Much like Socket T systems Socket J systems also feature a
land-grid array (LGA) design. This processor package also features two
notches again to ensure that the CPU is installed with the correct
orientation.

Some servers feature internal USB headers. It’s not uncommon to see
USB keys installed within servers as this provides the means to
remotely update server firmware during the boot process or to install
updated drivers during remote installation.

A number of fan trays are installed in the front of the server in
order to provide cooling to the components that reside behind. A total
of six
fans are installed here in redundant pairs.

Each fan tray can be removed simply by lifting it off the main
board. This image also shows the fan headers on the main board that
owers each pair of fans.
