The Active solution has thermal pads attached to the bosses on the base of the finned heatsink which make
direct contact with the surface of Northbridge, Southbridge and two voltage regulators on the daughter card to
help dissipate heat into the heatsink.
Figure 5: Heatsink bosses and thermal pads
Before fitting the active solution, it is necessary to spread some thermal grease to the surface of the boss which
will contact the CPU. Thermal grease is required as thermal pads provide less thermal conductivity than
required for the CPU. Note: the minimum amount of thermal grease should be used
Figure 6: secure the assembly using screws
To finish of the assembly, it is necessary to use screws to secure the active solution in place. This also protects
against the daughter board coming unseated from the host board during operation
