Description
The 14038axial fan leverages its large 140mm diameter to move more air at lower RPMs than smaller fans, resulting in excellent cooling with minimal noise. Available in 12V or 48V with PWM control, it's a go-to choice for high-airflow PC builds, 280/420mm liquid cooling radiators, and server chassis that demand quiet, reliable performance.

FAQ
Can I use it on a water cooling radiator?
Yes, a static pressure of 21.5mmH₂O is sufficient to penetrate a standard radiator. It is primarily designed for 280mm or 420mm radiators, mounted on a corresponding sized heatsink bracket.
Can we get samples for testing for free?
Yes, we can provide free sample testing for low-cost products.
What is the warranty period for a fan?
Under normal usage conditions, we offer a 12-month warranty period.
How to obtain the samples?
First, Contact us at [email protected]. Then, tell us your product requirements (voltage, size, speed, etc.). After receiving your information and confirming your requirements, we will produce a sample within three days.
