STEP 1

STEP 2

STEP 3

STEP 4

STEP 5

Apply some thermal grease on the CPU 

properly.

Caution : 

Before installation, please 

turn off the power, unplug the 

power cord, and be sure to 

remove the sticker from the 

bottom of the cooler unit.

Unlock screws on the AMD bracket and 

remove the bracket.

Place the two 775 brackets between the copper base and the cooler unit. 

Align the holes of the bracket with the holes of the copper base. Secure the 775 brackets 

with supplied bracket screws. Make sure the screws are evenly and firmly fastened. 

Before installation, please make sure the pin is on the right direction ( as Figure A ).

To remove the cooler, turn the four pins to the removing 

direction ( as Figure B ) and pull them up.

Plug the 3-pin connector of the cooler 

into the motherboard’s CPU fan socket.

STEP 6

Align the pin of the cooler with 

the hole of the CPU on the 

motherboard and push down 

the pin diagonally. 

Please make sure the four 

pins are firmly secured. 

STEP 1

Mount the AMD K8 / AM2 

clip on the AMD bracket of 

the cooler.

STEP 2

Caution : 

Before installation, please turn off the power, unplug the power cord, and be 

sure to remove the sticker from the bottom of the cooler unit.

STEP 3

side of AMD K8 / AM2 clip in 

the salient point of the CPU 

cooler bracket; push down 

and secure the bar on the 

clip firmly.

STEP 4

Lock the tab on one side of 

AMD K8 / AM2 clip in the 

salient point of the CPU 

cooler.
