140mm case fan DeepCool FD14 WH, 140x140x25 mm, white, 3-pin

DeepCool FD14 WH is a 140 x 140 x 25 mm white case fan engineered to improve PC airflow and maintain stable internal temperatures. The fan is compatible with standard 140 mm fan mounts and connects via a 3‑pin power connector to motherboard headers or external fan controllers. Designed for general chassis ventilation, the DeepCool FD14 WH helps reduce heat buildup around CPU, GPU and other components without occupying additional drive or expansion slots.

Advantages

The DeepCool FD14 WH offers a balance of airflow and quiet operation suitable for desktop and workstation enclosures. Its 140 mm diameter provides greater air movement at lower rotational speeds compared with smaller fans, which can lower noise levels while maintaining effective cooling. The neutral white finish integrates with many system builds and the standard frame and mounting holes make installation straightforward.

Suitable for

• Case ventilation in mid-tower and full-tower desktop PCs
• Replacing or upgrading existing 140 mm chassis fans to improve airflow
• Cooling radiator or single-fan intake/exhaust positions in workstations
• Systems that use 3‑pin fan headers or external fan controllers

Key specifications

• Size: 140 x 140 x 25 mm
• Frame color: white
• Connector type: 3‑pin power connector
• Mounting: standard 140 mm mounting pattern
• Function: chassis airflow and component cooling

How to use

Mount the DeepCool FD14 WH into a compatible 140 mm fan position using the four mounting screws that match the standard hole pattern. Connect the 3‑pin cable to a motherboard fan header or to a compatible external fan controller. When connected to a 3‑pin header, speed control is typically voltage-based; verify BIOS or controller settings to set desired fan profile and minimum RPM thresholds. Orient the fan so airflow direction aligns with the case’s intended intake or exhaust configuration.

Recommendations

For optimal results, position the fan to support the case’s overall airflow path—intake at the front or bottom and exhaust at the top or rear. Clean the fan and dust filters periodically to avoid reduced performance. If silent operation is a priority, configure a conservative fan curve in BIOS or in a fan controller to keep RPMs low under light loads while allowing increases when temperatures rise.
