Fully control main fan of Delta3

Hi,

for use of Delta3 on the film set, I'd like to fully take control of a fan over: as many film devices, to limit RPM of a fan to bare minimum while rolling at the cost of raising temperature of the metal. Once recording is cut, then the fan can raise to basically any RPM to quickly flush the heat out of the box and cool the device down for another roll.

Please, is the fan connected to the board in a way that it'd be possible to intercept wiring and using custom electronics, to control RPM as needed? From photos, I can't really see any wiring to the fan and assume it is nicely hidden in the hardware… which is a problem for me, unfortunately.

Of course, temperature sensor of the CPU and possibly another extra sensor of the cooling metallic block shall be monitored and if temperature is raising above reasonable limits, RPM would raise anyway to protect the hardware, indeed.

Any clarification very welcome, thank you so much in advance!

Kind regards,
Stepan
