Table 2 Recommended Heatsink Plate Thermal Compounds
Spread the required amount of thermal compound over the clean heatsink plate. Firmly press
the V1000 finless drive against the metal panel and hold it in place against the heatsink plate
for a few seconds. Wipe away any excess thermal compound from around the heatsink plate
edges.

Figure 4 Application of Thermal Compound
Note: Surface milling of the metal panel to within 0.05 mm (0.0019 in) flatness is required if use of
less thermal compound is desired.
Ensure the V1000 finless drive is firmly pressed against the metal panel for a few seconds to
ensure proper thermal transfer.
