DF1203848B2UN 120mm 48V Cooling Fan – Avalon Miner Chassis
The DF1203848B2UN is a 120 × 120 × 38 mm high-speed DC cooling fan built specifically for Avalon miners running on the 48 V chassis rail. Unlike the standard 12 V miner fans, this unit pulls power directly from Avalon's 48 V intermediate rail — ensuring ideal cooling performance and preventing potential damage from overheating.
Electrical: DC 48 V / 1.5 A with 4-pin connectors for easy front + back system connection. The compact 120 × 120 × 38 mm footprint fits all major AvalonMiner chassis variants — drop-in replacement for the factory unit when bearings wear out or blades crack.
Typical Use Cases
- Failed factory fan replacement — Avalon OEM 48V fan worn out.
- Bearing noise reduction — replace rattling factory units.
- Field service kits — common-failure inventory for Avalon fleet maintenance.
- Refurb / resale — fresh fans on rebuilt Avalon miners.

FAQ — DF1203848B2UN Fan
Q: Why 48V instead of standard 12V?
A: Newer Avalon chassis run the fan loop off the intermediate 48 V rail to reduce conductor cross-section. Don't substitute a 12 V fan — it'll burn out instantly on the 48 V supply.
Q: Compatible across A1166 / A1246 / A1346 / A1466?
A: 48 V fan is used on multiple Avalon generations. Match the connector pinout + chassis fan-header before ordering.
Q: Bulk pricing?
A: Yes — email contact@lys-sz.com.
