SKU CH-DNAT-NYE1Y

Two 50 mm 12 V fans deliver 10.9 CMF airflow at 29 dBA for compact case cooling

  • Two fans cool dual zones in compact builds
  • 4500 RPM spins 10.9 CMF airflow through tight spaces
  • 29 dBA runs quietly during long sessions
  • 12 V DC power fits standard motherboard headers
  • 50 mm square frame mounts on 40 mm centres

Two-Pack 50 mm Case Fans

This set contains two 50 mm square fans designed for compact chassis or targeted component cooling. Each unit runs on 12 V power and spins at 4500 RPM to move 10.9 CMF of air. The 29 dBA rating indicates quiet operation suitable for noise-sensitive builds.

Sustained Thermal Performance

At 4500 RPM the fans deliver a steady 10.9 CMF airflow for continuous heat removal during long workloads. The seven-vane plastic impeller maintains consistent speed without ramping noise beyond the rated 29 dBA. DC 24 V specification on the label suggests the motor tolerates higher voltage margins during extended use.

Compatibility Checklist

Verify your motherboard or fan controller provides a 12 V header for each fan. Mounting holes measure 4.5 mm diameter on 40 mm centres, so confirm the target surface matches this pattern. The 17 cm lead length may require an extension cable if routing to a distant header.

Questions about this item

How much heat and noise does a 4500 RPM fan rated at 29 dBA add to a case running all day?

Each fan spins at 4500 RPM and is rated at 29 dBA, so a pair adds modest airflow with low audible noise during continuous operation.

What connector or voltage must my motherboard or controller provide for these 12 V fans?

The fans require a 12 V DC supply; the 17 cm leads end in a standard two-pin or three-pin header compatible with typical motherboard fan headers.

Will the 40 mm mounting holes line up with the fan slots on my older chassis?

The mounting holes are spaced 40 mm centre-to-centre with a 4.5 mm diameter, matching the common 50 mm fan pattern used on many legacy cases.
