40mm 4056 SM BB33 DC12V 1.82A Case Fan

The Zyvpee 40mm 4056 SM BB33 DC12V 1.82A case fan is a 40 by 56 millimetre dual ball bearing cooler designed for 12 volt DC operation drawing 1.82 amps. It serves as a direct replacement for server units identified by part numbers 663120-001 and 677059-001. The non-LED black housing fits standard 40mm mounting points in compact chassis.

Replaces 663120-001 and 677059-001 Server Fans

This unit matches the GFM0412SS SM BB33 specification used in specific server cooling assemblies. The dual ball bearing construction targets longer service intervals than sleeve bearing alternatives in continuous duty environments. The upgrade is justified when the original fan exhibits bearing noise, reduced airflow or complete failure in the host system.

Suits Server Repair and Compact Chassis Maintenance

Technicians servicing equipment requiring the exact 40 by 56 millimetre footprint and 12 volt 1.82 amp electrical profile will find this a compatible spare. Builders needing PWM speed control, larger frame dimensions, lower current draw or RGB illumination should select a different model matching those requirements.

Questions about this item

Will the 40 mm by 56 mm frame fit the 663120-001 or 677059-001 server slots?

The fan measures 40 by 56 mm and is listed as a direct replacement for part numbers 663120-001 and 677059-001, so it matches those server mounting holes.

How do I connect the two-wire 12 V 1.82 A lead without reversing polarity?

Align the red wire to the 12 V pin and the black wire to ground on the server header; the keyed connector only seats one way, preventing a reversed connection.

When should I plan to swap out the 2-ball bearing GFM0412SS SM fan?

Listen for new rattling or a drop in airflow; when either appears, replace the fan to keep the server cooling reliably.
