SKU CH-JMN7-SJZ0Q

A 120 mm square case fan measuring 38 mm thick with a 4-pin PWM connector for 12 V power and 1.40 A current draw

  • Delivers strong airflow with 120 mm frame and 38 mm depth
  • Precise speed control via 4-pin PWM connection
  • Reliable 12 V DC operation at 1.40 A current draw
  • Compact 120x120x38 mm size fits standard case mounts

Nidec B35502-35MIT 12 V 1.40 A 4-pin case fan

This Nidec cooling fan is built around the B35502-35MIT model and runs on a 12 V DC supply drawing 1.40 A. The four-wire, 4-pin connector provides PWM speed control for precise airflow management. Its frame measures 120 mm by 120 mm with a 38 mm thickness, matching standard 120 mm mounting points in many chassis. The unit is supplied new and ready for installation.

Suitable for 120 mm mounts needing 38 mm depth

This fan suits builders who need a 120 mm PWM fan with a 38 mm thick frame and a 4-pin header. It is not suited for builds limited to a slimmer frame or a 3-pin voltage-controlled header. It is also not suited for situations requiring a different voltage or current rating than 12 V and 1.40 A.

Highlights

  • Delivers strong airflow with 120 mm frame and 38 mm depth
  • Precise speed control via 4-pin PWM connection
  • Reliable 12 V DC operation at 1.40 A current draw
  • Compact 120x120x38 mm size fits standard case mounts

Questions about this item

Will the 120x120x38mm frame fit my standard 120mm mounting points?

Yes, the 120mm square frame aligns with standard 120mm screw holes; the 38mm thickness requires enough clearance behind the mount.

What is the correct way to connect the 4-pin connector to the motherboard header?

Align the keyed 4-pin plug with the 4-pin CPU or chassis fan header and press straight in; forcing it offset by one row bends pins and prevents PWM control.
