If you are not installing a new heatsink, use the alcohol pads to remove any residual thermal
compound from the bottom of the heatsink.
Apply thermal compound to the top of the CPU.
For best application, use the entire contents of the pre-filled syringe and apply the compound in
a star (asterisk) pattern.
Carefully position the heatsink over the CPU, aligning it with the mounting posts.
After the heatsink contacts the CPU, minimize the movement .
Caution –
If the heatsink is moved too much during its installation, the layer of thermal
compound might become uneven, leading to component damage.
To secure the heatsink to the motherboard, alternately tighten the four screws.
Alternately turn each screw one full turn until all the screws are tightened fully.
Install the air duct. See “How to Install the Air Duct”on page 53 .
Prepare the server for operation. See “How to Prepare for Operation”on page 26 .
