Installing the A70 in to a motherboard is really simple and only requires a few steps. The first step is to make sure that your backplate is aligned in the right spot, from 775, 1156 or 1366. They clips slide by pushing hard enough or by pulling out the locking tab. We’re using a socket 775 CPU for this installation.
You can then go ahead and attach the retention plate to the heatsink via the four small screws provided. I recommend trying to install the screws on the bottom of the base, rather than the top, while there are screw cutouts on the top; it’s just not feasible with the heatfins in the way.
You can then go ahead and apply the included thermal paste.
Then you must place the backplate to the motherboard and install the heatsink. It is recommended to install the cooler with the convex side on the left and the concave side on the right. This way you’ll have optimal airflow over the CPU cooler once you install the fans. The heatsink can be secured to the motherboard via four thumbscrews.
You can then attach the fans so that the airflow is going over the heatsink and out the other side to exit the case through the exhaust fan. Just look for the small arrows around the fan to know which way the airflow is going.
The fans just snap on via the two clips on either side of the fan housing. These clips lock into the small cutout on the heatsink, making for a quick and easy fan installation. You can now attach both of the fans to the coupler cable to provide power to both fans via one connector.
The cooler should fit well inside any case. If you have any cable connections on the motherboard around the CPU cooler, you might want to attach them prior to securing your motherboard to the case, especially if you have a bottom mounted PSU.
The cooler does take up a lot of room once it’s installed, but it looks nice inside of the case.
