Install Heatsink
14.
Apply thermal grease to the heatsink as shown. Apply 5 small dabs/drops of thermal grease in an X pattern.
Do not spread the grease. (If using a new heatsink, remove the protective film covering the thermal interface
material on the bottom side of the heat sink; no grease is needed for this situation.)
15.
Attach the heatsink. Position the heatsink fins in the proper orientation.
a. Start with screw A and engage the screw threads by giving it two rotations. (Do not fully tighten.)
b. Proceed to screw B and engage screw threads by giving it two rotations. Continue by engaging screws C
and D.
c. Continue by giving each screw, using the same pattern, two rotations each time until each screw is lightly
tightened. Torque each screw to 8 inch-lb.
CAUTION:
●
The heatsinks for processor 1 and processor 2 are different.
● S2600 motherboards use two different heatsinks for processors 1 and 2. The two heatsinks are
not interchangeable. Using the wrong heatsink will cause serious thermal damage. A heatsink
(and socket cover) is required even if no processor is installed.
