KEYFANCLUB H12-3PIN 120mm 12V 3-Pin 2000RPM 2-Pack
Two 120 mm 12 V fans with metal grilles and mounting hardware, 2000 RPM airflow at 30 dB for PC cases, servers or DIY cooling projects
- Quiet 30 dB operation keeps workspaces undisturbed
- 65 CFM airflow clears heat from servers and printers
- 2000 RPM speed sustains 24/7 cooling loads
- 105 mm hole pattern fits standard 120 mm mounts
- Two fans with metal grilles and screws ship ready to install
Two-Fan Cooling Kit
This two-fan kit delivers 12 V DC airflow for desktop PCs, server racks, 3D printer enclosures and similar DIY ventilation projects. Each 120 mm unit spins at 2000 RPM and moves 65 CFM while producing 30 dB of noise. The bundle includes two metal safety grilles and mounting hardware for immediate installation.
Three-Pin Voltage Interface
The 3-pin connector supplies fixed 12 V power without PWM speed control, so fan speed stays constant at the rated 2000 RPM. Motherboard headers that expect a fourth PWM wire will still run the fans, but cannot regulate them. Builders who need variable speed or automatic thermal curves should choose a 4-pin PWM model instead.
Standard 105 mm Mounting
The 105 mm hole pattern matches most 120 mm fan mounts in cases, cabinets and rack enclosures. Screws and grilles are provided, so no extra parts are required. The only common issue is cable reach in larger chassis; the fixed-voltage leads are short, so plan routing or use an extension if the header is far from the mount.

Questions about this item
Should I pick the 2-pack or a single fan for my build?
The product is sold as a 2-pack containing two 120mm fans, two metal grilles and mounting hardware. Buying the bundle covers both intake and exhaust positions in a typical case or server rack without ordering extra parts.
What does the 2000 RPM rating mean for actual cooling and noise?
At full speed the fan moves 65 CFM while producing about 30 dB of noise. That airflow is enough for steady heat removal in a gaming PC, server cabinet or 3D-printer enclosure, and the sound level stays quiet enough for a living-room media console.
How does the 3-pin 12 V connector limit speed control?
The 3-pin connector provides a constant 12 V supply and a tachometer signal, so the fan runs at its fixed 2000 RPM. Motherboards or fan controllers that only support voltage regulation cannot lower the speed; PWM control is not available on this model.
