1.2 Installing the heatsink and fan
To install the CPU heatsink and fan:
1. Select an Intel-certified or
AMD-certified heatsink and fan assembly based on your
motherboard. There are 3-pin (left) and 4-pin (right) fan connectors. Only CPU fans
with 4-pin connectors supports the ASUS Q-Fan technology.
For Intel-certified heatsink:
2. Some heatsinks will come with
pre‑applied thermal paste. If so,
do not scrape it off and remove
the protective film only before
installation. If not, before installing
the heatsink, apply several drops of
thermal paste to the exposed area
of the CPU that the heatsink will be
in contact with. Make sure that it is
spread in an even thin layer.
To prevent contaminating the paste, DO NOT spread the paste with your finger
directly.
3. Orient each fastener with the
narrow end of the groove pointing
outward.
