2. Heatsink fan installation thru motherboard holes (mostly AMD

, some Intel platforms)

2.1 Pre-installation steps

Installation of the heatsink always necessitates removal of the motherboard from the chassis.

Remove the existing heatsink and carefully clean the microprocessor with alcohol

Apply the provided neoprene pads onto the chipset if applicable (see figures 1 and 2 page 1)

2.2 Installation of the mounting posts

Follow Figure 6 below to install the retention posts: install two 4-40 x 1.25” Philips screws with fiber washers on both sides of the
motherboard, and secure them with the provided 4-40 mini-nuts.

Figure 6

2.3 Heatsink assembly

Please refer to figure 3 page 1 to identify the adequate mounting holes for the brackets.

The heatsink brackets can be installed in two different fashions to allow more or less clearance with neighboring components:
a.

Bracket will be attached directly onto the heatsink as shown in figure 7.

b. A spacer will be placed between the bracket and the heatsink to position the bracket higher, and allow clearance for capacitors

in some motherboards (Asus A8N-SLI for example), as shown in figure 8.

To determine which of the above will be used, simply place the heatsink on the chipset, and visually identify possible clearance
issues.
