1. Place a rubber washer (part D) over each of the screws of the LGA775
backplate (part A).
2. Place the LGA775 backplate under the motherboard aligning the screws to fit
through the four holes available around the CPU as illustrated.

AK-922
3. Place the thick rubber pads (part C) over each of the four (4) screws so they
sit on the motherboard as shown.

4. Apply the proper amount of thermal compound on the CPU surface; a thin
layer is ideal, extra thermal compound will not improve performance. Make sure
the CPU surface is perfectly clean. If not, clean it with Isopropyl or Akasa
Timclean.
5. Position the cooler over the four mounting screws. The installation direction
of the heatsink will depend on your case and its airflow requirements.
6. Secure the cooler with the collar nuts (part B), one for each screw, tighten
the nuts gradually in a crosswise manner.

8. Connect the 4-pin fan connector to the CPU fan motherboard connector. If a
connector marked CPU fan is not apparent on the board, check the
motherboard manual for fan connection information.
1. Remove the retention bracket from the motherboard by removing the screws
(or pins in some motherboards).
Note: It may be possible that the removal of the original backplate is not required if the cooler spring loaded
screws are compatible.

7. Connect the 2-pin female LED connector to the 2-pin male power connector
from the fan.

3. Take off the pre-attached LGA 775 heatsink retention bracket and retain the
four (4) screws for the next step.
4. Place the K8 heatsink retention bracket (part F) on the heatsink base
aligning the fixing screws with the Fan bracket indents and the corresponding
screw holes.
2. Place the backplate provided (Part E) below the motherboard aligning the two
standoffs with the holes in the motherboard as illustrated.

6. Place the cooler on top of the CPU; align two spring loaded screws with the
backplate standoffs and secure the cooler by tightening the screws.
5. Secure the heatsink retention bracket with four (4) screws from step three.
Apply the proper amount of thermal compound on the CPU surface; a thin layer
is ideal, extra thermal compound will not improve performance. Make sure the
CPU surface is perfectly clean. If not, clean it with Isopropyl or Akasa Timclean.
7. Connect the 2-pin female LED connector to the 2-pin male power connector
from the fan.

8. Connecting the fan:
A. Remove a PCI slot backplate and install the fan control unit (part K).
B. Connect the 4-pin fan connector to the male connector of the Y cable.
C. Connect the 3-pin female connector (with red / yellow / black wires) to the fan control.
D. Connect the 3-pin female connector (with yellow / black wires) to the CPU fan
motherboard connector.
E. Connect the fan control to the 4-pin PSU connector.
For AK-921 installation follow the AK-922 manual steps 1-6 for LGA775 and
AMD K8. After that; connect the LED 2-pin connector with 4-pin PSU connector
using part G.
