Do: Bolt the splicer PCB to its printed spacer and mount the sandwich to a frame extrusion in the bay. Plug both 6020 fans into it and run the PCB FAN cable to the Leviathan port FAN2, pin PF7.
Check
The spacer is fitted, same short-circuit rule as the LED junction.
What you're looking at
The two 6020 fans are 60 × 60 × 20 mm axial fans that cool the electronics bay. The 3×2 splicer PCB joins them into one lead so a single Leviathan fan port drives both; its printed spacer keeps the bare board off the extrusion.
Tip
if the fans are not mounted yet, coil their leads and zip-tie them clear of the gantry; they go on with the skirts in Ch 11.
