COOLING
ASSEMBLY
AND
THE
CPU
1.
Remove the motherboard (see page 14).
2.
Let the cooling assembly cool before you touch it.
Both the cooling assembly and the CPU may be very hot.
3.
Disconnect the CPU fan cable from motherboard connector FAN1.
Several motherboard components are very close to the cooling assembly. Make sure not
to damage these components when removing or replacing the cooling assembly.
4.
Disconnect the clamp hooks from the two bracket slots closest to the DIMM slots.
To disconnect the clamp, press down on the clamp levers and pull the clamp crossbar
away from the bracket hooks.

5.
Lift off the fan/heatsink and set it aside.
If the clamp is not interfering, let the clamp’s other two hooks (close to the FAN1 side)
remain inserted in the bracket slots. Not removing the clamp may better protect the tall
capacitors from inadvertent damage.
Use caution when lifting off the fan/heatsink. The thermal compound adhesive on the
bottom of the heatsink may damage the CPU if you remove the fan/heatsink too
forcefully.
6.
Remove the CPU using the CPU socket lever.
To release the CPU, flex the CPU socket lever away from the retention post, and then lift
the CPU socket lever all the way up to vertical.
Grasp the CPU by its edges and carefully lift it from its socket.
