NZXT Control Hub - Digital RGB & PWM Fan Controller (AC-CRFR1-B1)

Overview

The NZXT Control Hub (AC-CRFR1-B1) is NZXT's current digital RGB and fan controller, built around the 8-pin single-cable standard used by its single-frame RGB Core and Ultra RGB fans. It provides five lighting channels - four NZXT 8-pin channels of up to 96 LEDs each plus one NZXT RGB channel for up to 40 LEDs across five devices, 424 LEDs in total - alongside five fan channels that mix PWM-only, switchable DC/PWM and a standard 4-pin header. NZXT CAM detects each attached device automatically through the hub's ID chip, and power comes from a single 8-pin PCIe cable rather than SATA.

Key Highlights

  • Five lighting channels: four NZXT 8-pin digital RGB channels rated for up to 96 LEDs each, plus one legacy NZXT RGB channel for up to 40 LEDs across five devices, for a combined maximum of 424 LEDs
  • Five fan channels on the same box: three NZXT 8-pin PWM-only channels, one NZXT 8-pin channel that drives PWM and DC fans, and one standard 4-pin header, each rated for 12V DC / 1.1 A / 13.2 W
  • RGB channels are rated 5V DC / 3.1 A / 15.5 W each, enough for long stacks of single-frame RGB Core or Ultra RGB fans, and Zero RPM mode stops fans entirely at low loads
  • Dedicated ID chip lets NZXT CAM auto-detect the hub and every connected device, so fan curves, per-LED effects and profiles are set without manual channel mapping
  • Mounts magnetically or with the included 3M Dual Lock fasteners or 2.5" SSD screws; a single 8-pin PCIe cable powers the hub and one internal USB 2.0 header handles control, backed by a 2-year warranty
