Our take on the Delta Electronics FFB0412UHN-C 40x40x28mm 12VDC DC Tubeaxial Fan

The Delta FFB0412UHN-C is a 40x40x28mm 12V DC axial fan built for high-static-pressure cooling in tight spaces. Its 28mm thickness and high-speed rotor push more air than slim 10mm or 20mm fans of the same footprint, which is why it turns up in 1U servers, network gear, and dense electronics. It is a bare fan with a 12V DC input and no PWM or RGB, so it suits builders who need raw airflow and can tolerate the noise. Expect loud operation at full speed; quiet-case builders should look at larger, slower fans instead.

Questions and answers

Is this fan loud?
Yes. It is a high-speed 40mm fan, so at 12V it produces noticeable whine. It is meant for equipment where airflow matters more than quiet, not for a silent desktop build.
Does it support PWM speed control?
No. It is a basic 12V DC fan, so speed is set by the voltage you feed it. You can slow it with a resistor or a separate controller, but it has no built-in PWM.
What is the 28mm thickness for?
The deeper frame holds a larger rotor, giving higher static pressure than 10mm or 20mm fans of the same 40mm footprint. Check your chassis clearance before fitting it.
What voltage does it need?
It runs on 12V DC. Do not connect it to a 5V or 24V rail; it needs a 12V source and the correct connector for your board or PSU.
Will it fit a standard 40mm fan mount?
The mounting holes match a 40mm fan pattern, but the 28mm depth needs clearance. Measure the space behind the mount before buying.
