## Description

GELID Solutions Silent 4 FN-SX04-42 40mm Case Fan

Review: Excellent Fan for Hot-end Fan Replacement on 3D Printer - Wanted a new fan on the hot-end for my Ender 3 Pro, wanted something quieter. Didn't want to pay $13 for a Noctua fan, so looked around a bit and found these fans by Gelid Solutions on desertcart. Same size, within 1db of the Noctua, but only $7.50. Added benefit that it's a hydro-bearing which should last forever compared to sleeve or ball bearing. 4200rpm @ 12vdc, whereas the Noctua is 4500/3700 RPM. This Gelid has a slightly more aggressive fan design so in comparing with my hand (no science here) it seems to put out as much or slightly more air than the Noctua. I will also say it's dead silent, I thought my Ender 3 Pro was off, so hit the power, and turned it off.... Added benefit (to me) is that it's a black fan housing with white blades, looks way nicer than the brown Noctua.
Review: I was looking for a silent cooling fan for my 3D printer - this one is awesome - The 30mm fan that shipped with my hot end was 10K and pushed 4 CFM. So I went in search of a silent fan that pushed at least as much air. I couldn't find a 30mm, but this 40mm at 18dB and 4.5 CFM seemed to fit my needs so I ordered. This fan is absolutely silent and I have had no issues with my printer since installing it.

## Features

- GREATER EFFICIENCY: Higher Airflow; The Silent 4 computer fan is designed to enhance airflow without increasing the noise level thanks to its optimized fan blades. Minimal design provides for less noise at a higher airflow. Reduced friction and noise
- INNOVATIVE DESIGN: Design of fan blades maximizes air flow and enables structured ventilation. The impeller is designed to minimize noise levels compared to similar products. The fan’s cutting-edge design delivers desired airflow and pressure
- TWO WAY INSTALLATION: The fan is built to gather the warm air and bring it out of the case, while drawing cool air into your case. This significantly helps your computer reach lower temperatures and prevents it from overheating
- HYDRO-DYNAMIC BEARING: The Hydro-Dynamic Bearing from Gelid extends the service life of the Silent 4 to 50,000 h MTTF at 40 ° C. Gelid’s products are expected to have a longer service life due to their hydro-dynamic bearing
- IMPROVED PERFORMANCE: The Silent 4 reaches a speed of 4200 rpm, an airflow of 7.65 CFM and a noise level of 18.9 dBA. Gelid's superior design improves the performance of the product. Gelid fans are built for exceptional performance

### ⭐⭐⭐⭐ Gelid Silent 4
*by G***N on February 10, 2023*

My first fan was DOA (tested before installing), returned & replaced. Second fan is working fine so far (just a few hours of use). The fan is installed in a homemade, portable “battery box” with solar charging. The fan is used to cool the solar charge controller. The fan only runs with solar energy is present, the only time ventilation/cooling is needed. The provided mounting screws worked fine for this application. It would be nice if it came with a grill, but hardware cloth worked. A simple wiring diagram would also be nice, but is available if you look for it. It is quiet, measuring about 40 db @ 1 foot.
