Model 3 Packs

  • Three-pack covers a 360 mm radiator or full-tower airflow
  • 500–3000 RPM PWM range scales speed to thermal load
  • 108 CFM airflow with 7.31 mmAq static pressure pushes through dense fins
  • Hybrid hydraulic bearing with dual oil circuits cuts friction noise below 39.9 dB
  • LCP blades reinforced with 40 % glass fibre resist warping at high RPM

Three-fan pack for radiator and case cooling

The Sudokoo MACH120 3in1 ships as a trio of 120 mm fans built for radiators, full-tower airflow and custom loops. Each unit uses a 3-phase 10-pole FOC motor with a hybrid hydraulic bearing and LCP blades reinforced with 40 % glass fibre. The 30 mm thickness adds structural rigidity for high-RPM operation.

Speed range and thermal headroom

PWM control spans 500 to 3000 RPM ±10 % and can drop to 0 RPM below 5 % duty for silent idle. At full speed a single fan delivers 108 CFM airflow and 7.31 mmAq static pressure while noise stays under 39.9 dB(A). The thick frame improves cooling contact on dense radiators or filtered intakes.

4-pin PWM interface and power limits

The 4-pin PWM connector draws 12 VDC at 0.50 A for 6 W per fan. Motherboard headers typically cap at 1 A, so two fans per header is the practical limit without a splitter or hub. Three fans on one header would exceed that rating and is not supported by the supplied connectors.

Questions about this item

Will the 30 mm thick 120 mm fans with 4-pin PWM fit alongside an existing fan on the same radiator?

Each fan is 120x120x30 mm with a 4-pin PWM connector; the 30 mm thickness adds depth so verify your radiator and case clearance before mounting them next to any other fan.

How can I confirm the fans are running at the correct speed after installation?

With PWM control the fans spin between 500 and 3000 RPM ±10 % and can stop at 0 RPM below 5 % PWM duty; monitor RPM in BIOS or fan-control software to verify they respond to temperature curves.

What comes in the package and what must be purchased separately?

The box contains three 120 mm fans with 4-pin PWM connectors; no fan controller, mounting screws or additional cables are included.
