## Overview

The Sunon MagLev KDE1204PKV3.MS.AF.GN is a compact 40x40x20mm cooling fan featuring advanced magnetic levitation technology that drastically reduces friction and noise. Operating at a quiet 18 dBA with a low-speed 5200 RPM, it delivers a steady 6.3 CFM airflow, ideal for laptops, servers, and compact electronics. Equipped with a 3-pin RPM sensor and backed by a 1-year warranty, this fan offers energy-efficient, reliable cooling performance for professionals who demand silent, efficient hardware solutions.

## Description

The Sunon MagLev KDE1204PKV3 MS.AF.GN is a type of cooling fan that uses magnetic levitation technology to reduce friction and noise. It has a size of 40x40x20mm and an RPM sensor. It is mostly used in electronic devices such as computers, servers and other electronic devices that require active cooling.

Review: Very Quiet - Because of the relatively slow speed (5200 RPM) this fan is very quiet(18 dBA) while still producing 6.3 CFM of airflow. Great alternative to the Noctua equivalent.
Review: Quiet - I am using this fan in a small 12 volt refrigerator, in the freezer compartment. It is quiet, and keeps the interior temperatures very even, and allows a lesser setting on the thermostat to keep sub 40f temperatures. A previous fan by Sunon that had twin ball bearings lasted 5 years in this use. It still works but got very loud. This Fan was desirable for its very low amp consumption, among the lowest of any fan available, and the reported current consumption is accurate.

## Questions & Answers

**Q: The image shows a unit with frequency output and the description says locked rotor output. Which one is it supposed to be?**
A: One of our customers just sent us this video when we asked which they needed--thanks for the shout out, Jon, and great notation Phil! Campbell, you do need the characters after the "V3" to denote what type of output. KDE1204PKV3.MS.AR.GN will work with this and KDE1204PKV3.MS.AF.GN will not. The one with the "R" actually indicates a tachometer (speed sensor) and the one with the "F" indicates a locked rotor alarm signal. However, Sunon discontinued the KDE models a few years back and replaced them with MF models (MF40201V3-1000U-A99 replaced KDE1204PKV3.MS.AR.GN). Feel free to reach out to us at 425-821-6400 if you have any questions.  see youtube video here https://www.youtube.com/watch?v=1_dM0pBRfOI

**Q: What type of connector comes with this fan?  Don't see it listed anywhere**
A: Doesn't matter when they send the wrong fan due to an incorrect product listing

**Q: Can i use this fan as a replacement for sunon model: kde1208pkv3?  if not, is an alternative?  i'm unable to locate a source for the kde1208pkv3.**
A: They are not the same fan. Your fan kde1208pkv3 is 80mm, our fan is 40mm

**Q: How long are the wires?**
A: relatively long.  50/50 they are attached to the wrong model due to an incorrect product listing.  Mine were also attached to what appears to be a counterfeit fan.

### ⭐⭐⭐⭐⭐ Very Quiet
*by H***R on October 9, 2024*

Because of the relatively slow speed (5200 RPM) this fan is very quiet(18 dBA) while still producing 6.3 CFM of airflow. Great alternative to the Noctua equivalent.

### ⭐⭐⭐⭐ Quiet

It is quiet, and keeps the interior temperatures very even, and allows a lesser setting on the thermostat to keep sub 40f temperatures.

### ⭐ Received a used product with dirt on the fan blades
*by V***V on October 24, 2022*

The fan itself is a great product with OK airflow and low noise level. One of the two fans I received, in the sealed bag, was clearly used with visible dust on the fan blades and the mounting holes had already been threaded. These fans could be taken off used equipment and sold off as used. You can the the dirty q-tip in the pictures after wiping the fan blades with it. So overall, this was a poor shopping experience with the vendor (CoolerGuys) and it maybe a hit or miss if you get a new/low usage fan or one with heavy use and dirt on the blades.
