8 Channels PC Fan Speed Controller with Knob, 12V PWM Cooling Fan Hub, PCI Bracket Mount, SATA Power Supply, Manual Speed Adjustment for CPU Case VGA HDD Fans

This 8-channel fan speed controller hub is an excellent cooling management accessory for DIY desktop computers. Equipped with one adjustable control knob, it allows users to manually adjust the overall rotation speed of all connected cooling fans conveniently. You can balance cooling performance and operating noise freely according to different working loads of your PC.

The fan hub supports up to eight 12V cooling fans, compatible with both 3-pin voltage-controlled fans and 4-pin PWM fans. It works perfectly with case fans, CPU auxiliary fans, graphics card fans and hard drive cooling fans, solving the problem of insufficient fan headers on mainstream motherboards.

Adopting SATA power input design, the controller draws power directly from the computer power supply instead of motherboard fan ports, avoiding overloading the mainboard and ensuring sufficient and stable power supply for all cooling fans. Built with standard PCI slot bracket, you can firmly install this controller on the rear PCI position of your chassis without extra fixing accessories.

Stepless speed regulation brings flexible adjustment: turn the knob clockwise to increase fan speed for stronger heat dissipation during high-load gaming or rendering; turn counterclockwise to reduce fan speed to cut down operation noise under light daily use.

Suitable for gaming PCs, workstations and silent home computers.

Kind Reminder: This single-knob model controls all fans synchronously. Independent separate speed regulation for each fan is not supported. Please calculate the total power consumption of all connected fans to avoid overload.
