6. Place the thermal pad on top of the PCIe card.
Note
Use of thermal pad
Distance between card and heatsink H1=5.9mm, gap=H1-H
• If 0 < gap < 1, use 1 mm thermal pad
• If 1 < gap < 2, use 2 mm thermal pad
• If 2 < gap < 3, use 1 mm and 2 mm thermal pads together
This thermal pad is included in the accessory pack and has a thermal conductivity of
