Compact 40 mm PWM case fan

The Delta FFB0412GHN is a 40 mm square frame fan with a 28 mm thickness designed for tight chassis spaces. It runs on 12 V power and draws .6 A, making it suitable for small form-factor builds or targeted component cooling.

4-pin PWM connector simplifies installation

The standard 4-pin PWM header allows motherboard speed control without extra adapters. Limited clearance in ultra-slim enclosures may prevent mounting, and the high current draw can exceed some low-power fan headers.

Questions about this item

How can I confirm the PWM control is functioning after connecting the 4-pin header?

The fan speed should vary smoothly with the PWM duty cycle sent from the motherboard, and the RPM reading in BIOS or monitoring software will change accordingly.

What is included with the FFB0412GHN and what must be sourced separately?

The package contains the 40 mm × 40 mm × 28 mm fan with a 4-pin PWM connector; mounting screws and any fan filters or splitters are not included.
