Step 4.
Use a clean area of the cleaning pad to wipe the thermal grease from the microprocessor; then,
dispose of the cleaning pad after all of the thermal grease is removed.

Step 5.
Use the thermal-grease syringe to place 9 uniformly spaced dots of 0.02 mL each on the top of
the microprocessor. The outermost dots must be within approximately 5 mm of the edge of the
microprocessor. This is to ensure uniform distribution of the grease.

Note:
0.01 mL is one tick mark on the syringe. If the grease is properly applied, approximately half
(0.22 mL) of the grease will remain in the syringe.
Step 6.
Install the heat sink onto the microprocessor as described in “Installing a microprocessor and
heat sink” on page 276.
Removing a heat sink
Use this information to remove a heat sink retention module.
Read the safety information in “Safety” on page v and “Installation guidelines” on page 29.
If you are replacing a server component in the server, you need to turn off the server and peripheral devices,
and disconnect the power cords and all external cables.
To remove a heat sink retention module, complete the following steps.
Step 1.
Carefully turn the server on its side so that it is lying flat, with the cover facing up.
Attention:
Do not allow the server to fall over.
Step 2.
Unlock and remove the left-side cover (see “Removing the left-side cover” on page 182).
Step 3.
Remove the air baffle (see “Removing the air baffle” on page 188).
Step 4.
Rotate the heat sink release lever to the fully open position.
