Step 3
Install a heatsink:
Caution
The heatsink must have a new, undamaged thermal pad on the heatsink-to-CPU surface to ensure proper
cooling. If you are replacing a heatsink that was previously installed, you must remove the old thermal
pad. If you are installing a new heatsink, skip to step
c.
below.
a.
Apply an alcohol-based cleaning solution to the old thermal pad and let it soak for a least 15
seconds.
b.
Wipe all of the old thermal pad off the heatsink using a soft cloth that will not scratch the heatsink
surface.
Caution
Damage to the heatsink surface can damage the heat transferring properties of the heatsink.
c.
Peel the protective film from the thermal pad that is on the bottom of the new heatsink.
d.
Align the heatsink captive screws with the motherboard standoffs, then use a Number 2
Phillips-head screwdriver to tighten the captive screws evenly until the screws stop against the
captive springs.
Note
Alternate tightening each screw evenly to avoid damaging the heatsink or CPU.
e.
Replace the top cover.
f.
Replace the server in the rack, replace cables, and then power on the server by pressing the
Power
button.
