Square black frame 120 mm fan with transparent blades and three-pin connector

SXDOOL

SXDOOL 120 mm 1000 RPM 50 CFM 11 dB 3-pin case fan

SKU CH-7ZE9-BCMQ0

A 120 mm case fan moves 50 CFM at 1000 RPM while producing only 11 dB of noise

  • Quiet operation at 11 dB for silent builds
  • 50 CFM airflow cools chassis efficiently
  • 1000 RPM full speed with motherboard speed regulation
  • Low 1.44 W power draw reduces system load
  • 120 mm standard size fits most cases

120 mm ultra-quiet case fan

This 120 mm fan runs at 1000 RPM and moves up to 50 CFM while producing only 11 dB of noise. It is built for chassis cooling and as a replacement for 12 cm power-supply fans in high-reliability server applications. The 3-pin connector supports speed measurement and regulation on compatible motherboards. Buyers who need higher airflow or PWM control should look elsewhere.

Build integration

The frame measures 120 by 120 by 25 mm with a 10.5 cm hole spacing that matches standard 120 mm mounting points. It draws 0.18 A at 12 V for 1.44 W input power, so it adds minimal load to a 12 V rail. The 3-pin interface plugs directly into a motherboard header; on many boards it will run at full speed, which remains very quiet. Builders needing a 4-pin PWM header or a thinner profile cannot use this model.

Sustained-load behaviour

At full speed the fan delivers 58 Pa of static pressure to push air through restrictive grilles or filters continuously. The low 11 dB acoustic output stays consistent during extended operation, making it suitable for always-on servers. The sleeve-bearing design and 160 g weight indicate a focus on long-term reliability rather than peak performance. Users requiring variable speed curves tied to temperature sensors will not get that function from the 3-pin connection alone.

Highlights

  • Quiet operation at 11 dB for silent builds
  • 50 CFM airflow cools chassis efficiently
  • 1000 RPM full speed with motherboard speed regulation
  • Low 1.44 W power draw reduces system load
  • 120 mm standard size fits most cases

Questions about this item

How much airflow does the 1000 RPM fan move at full speed?

The fan delivers a maximum air volume of 50 CFM when running at 1000 RPM ±10%.

What noise level and power draw should I expect during continuous operation?

At full speed it produces 11 dB of noise while drawing 1.44 W at 12 V and 0.18 A.

Does my motherboard need a specific header to use the speed measurement and regulation features?

The 3-pin connector provides speed measurement and regulation only on brand motherboards that support temperature-based control; otherwise the fan runs at full speed.
