Parts:
- 50×50×15 centrifugal fan, trimmed ×1 · Belts, Chains & Fans box
- M3×6 FHCS ×2 · Fasteners, Tools & Misc box
Do: Drop the trimmed blower into the upper cavity, above the hotend fan, outlet feeding the ducts, and fix it with two M3×6 FHCS. Blower wires exit right. Part cooling is the top fan, the hotend fan the bottom.
Check
The blower is square in the upper cavity with the 4010 below it, the impeller spins freely, and the outlet aims down through the duct.
What you're looking at
The trimmed 5015 goes in the upper cavity, above the hotend fan. Which fan is which matters: the config drives them on different pins, and Ch 13's fan verification tests whether top and bottom got swapped.
Good stopping point · ~20 min since the last one
the Stealthburner body is fully populated: three LEDs seated, diffusers pushed forward, both fans in, every wire exiting on the right. Rest it face-down on a soft cloth. Do not put weight on the diffuser faces or spin the impellers with anything but a finger.
