Using a Heatsink

It is possible to use a heatsink with the PiCoolFAN4 and the combination of these two cooling tools
provides excellent results.
To use a heatsink with the PiCoolFan4, the user needs to fit a GPIO header/extender to raise the height
of the PCB (as standard, the PCB is close to the Raspberry Pi CPU to ensure the included temperature
sensor can function as per design).
Users should ensure that the PiCoolFAN4 is 3.5mm away from the heatsink, and test/adjust cooling profile
thresholds to account for the different conditions (see page 13).
Alternatively, users can make use of the included software to use the Raspberry Pi temperature sensor
for fan control (see page 18).
