SXDOOL SXD12025 3IN1 3-Fan DC Cooling Kit 120x120x25mm

SKU CH-TRJR-G2ZAP

Three 120 mm dual-ball-bearing fans with adjustable 3–12 V DC control deliver 48–94.5 CFM each for mining rigs and equipment cabinets

  • Adjustable 3-12V DC power from 100-240V AC adapter for safe low-voltage fan operation
  • Three 120x120x25mm fans with 105mm mounting spacing fit standard mining rig bays
  • Per-fan airflow scales from 48 CFM at 3V to 94.5 CFM at 12V for targeted cooling
  • Dual ball bearing and seven sickle blades deliver 1100-3200 RPM speed range with 18.8-38.5 dBA noise
  • Complete kit includes 3-way splitter cable and 230mm leads for simple 5.5x2.1mm DC connection

Complete 3-Fan DC Cooling Kit

The SXDOOL SXD12025 3IN1 kit contains three 120x120x25mm DC fans, an adjustable 100-240V AC-to-DC adapter rated up to 2A, and a 3-way splitter cable. It is built for targeted airflow in BTC mining rigs, workstation cabinets, and equipment enclosures where the mounting pattern and connector match. Each fan uses a 5.5x2.1mm DC connector and a 230mm lead.

Adjustable Speed Replaces Fixed-Flow Fans

Unlike single-speed fans, this kit lets you set the adapter output between 3V and 12V to match cooling needs. At 3V a fan runs at 1100 RPM delivering 48 CFM at 18.8 dBA; at 12V it reaches 3200 RPM and 94.5 CFM at 38.5 dBA. The jump is worth it when noise tolerance or thermal headroom changes across deployments.

For Builders Who Can Verify Fit And Polarity

This kit suits installers who can confirm 105mm hole spacing, 4.3mm mounting holes, correct connector polarity, and adequate adapter headroom for three fans. It is not for buyers who need PWM motherboard control, larger frame sizes, or fans rated for direct AC mains connection.
