SKU CH-J2BR-NREVM

Three 120 mm fans with swappable blades deliver 57.56 CFM at 1.75 mmH₂O while running as quietly as 25 dBA

  • Fan Size120mm
  • ColorBlack
  • LEDARGB
  • Near-silent cooling at just 25 dBA maximum noise
  • Swappable blades let you switch between intake and exhaust airflow
  • 56 CFM airflow moves large air volume through your case
  • 75 mmH₂O static pressure pushes air through dense radiators and filters
  • 400-1600 RPM range balances quiet idle with strong load performance

Three-Fan Pack for High-Airflow Builds

The GAMDIAS NOTUS M1 kit supplies three 120 mm case fans in black with addressable RGB lighting. Each unit spins between 400 and 1600 RPM to move up to 57.56 CFM at a static pressure of 1.75 mmH2O. The hydraulic bearing and closed-loop control system target quiet, consistent operation across the speed range.

Swappable Blades Reverse Airflow Direction

Every fan ships with a second blade set that installs without tools to flip the unit from intake to exhaust. This lets builders match the fan curve to either front-mount or rear-mount positions using the same hardware. ARGB illumination remains functional regardless of which blade orientation is chosen.

Standard 120 mm Mounting With PWM Control

The fans fit any 120 mm mounting point and connect via a 4-pin PWM header for motherboard speed control. The 1 mm tip clearance demands careful alignment during installation; forcing the frame can increase noise beyond the rated 25 dBA. Cable routing for three ARGB connectors and three PWM leads requires planning in tight chassis.

Questions about this item

How long will the hydraulic bearing last before I need to replace the fans?

The hydraulic bearing is built for long-term reliability, and the PBT construction resists wear even at the 1600 RPM maximum speed.

At 1600 RPM the fans hit 25 dBA — does that noise level stay constant during extended loads?

Yes, the closed-loop control keeps the 25 dBA rating steady at full speed, so sustained workloads do not increase audible noise.

What happens to airflow and static pressure when the fans run at 1600 RPM all day?

At the 1600 RPM ceiling the fans maintain 57.56 CFM airflow and 1.75 mmH2O static pressure without thermal throttling.
