TNN 500AF
NOTE) The VGA Case Block Base already has thermal grease coated underneath, and
should not be taken off under normal circumstances.
Apply a thin layer of thermal grease on the VGA chipset.
NOTE) Most VGA chipsets on the VGA card have a concave curvature towards the middle and
need more thermal grease at the center.
Make sure the VGA Block Base is level and firmly installed onto the VGA chipset using the
Paper Washers, the VGA springs, and the VGA Finger Bolts A(M2.5).
Apply thermal grease evenly onto the grooves on the VGA Case Block Base that come in
contact with the VGA Heatpipes, and install the VGA card on the motherboard.
