(no image — see LDO Nevermore guide § Install Fans)
Parts:
- Nevermore bridge PCB ×1 · Belts, Chains & Fans box
- the saved connector pigtail · already on the bench
- soldering iron and solder · tool
- multimeter · tool
Do:
- Solder both fans' wires and the pigtail to the bridge PCB, red to the top pads, black to the bottom.
- Arrange the wires as the guide's photo shows.
- Meter for a short between positive and negative.
Check
Continuity reads open between + and −; all six joints shiny and mechanically sound; PCB sits in its compartment without pressing on a wire.
What you're looking at
The bridge PCB is a small board that joins both fans and the saved pigtail into one 24 V pair, red to the top pads, black to the bottom. A solder bridge here puts a dead short across the mainboard's 24 V fan output.
Caution
A bad solder here shorts a 24 V rail. LDO: "A bad solder will result in permanently damaging the controller board." Do the meter check before anything gets plugged in. src
Good stopping point · ~20 min since the last one
both fans seated in the plenum, leads trimmed to length and soldered to the bridge PCB, and the pair metered for a short. The plenum is open and unglued.
