Now no sound from the fans at all, for your reference I am not using any low noice adaptors. I will purchase two more to replace in 24 port PoE switch. Review: Very professional - As expected. Is not very silent but not too loud either. Comes with all kinds of connections and is very professional. Im using it for my 3d printer and the wind power is just 👌🏻. Will probably replace the internal fan with another noctua too ## Features - Connector & pin- configuration : 3-pin I Rotational speed : 5000 RPM - Cable length : 20cm + 30cm NA-EC1 extension cable I Low-Noise Adaptor (L.N.A.) - Frame technology : AAO (Advanced Acoustic Optimisation) I Blade geometry : A-Series with Flow Acceleration Channels - Max. input power : 0,6 W I Operating voltage : 12 V - 6 Year Warranty ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B071J8CZP9 | | Best Sellers Rank | #36,152 in Computers & Accessories ( See Top 100 in Computers & Accessories ) #176 in Case Fans | | Brand | Noctua | | Brand Name | Noctua | | Compatible Devices | Desktop, Laptop | | Cooling Method | Fan | | Customer Reviews | 4.8 out of 5 stars 2,588 Reviews | | Global Trade Identification Number | 09010018100112 | | Importer Contact Information | Acro Engineering Company, Z-41, Sanjay Colony II, Pocket Y, Sanjay Colony, Okhla Phase II, Okhla Industrial Estate, New Delhi, Delhi 110020 | | Included Components | Case Fan | | Item Type Name | Case Fan | | Item Weight | 50 Grams | | Manufacturer | Noctua, Rascom Computerdistribution Ges.m.b.H.

Now no sound from the fans at all, for your reference I am not using any low noice adaptors. I will purchase two more to replace in 24 port PoE switch. ### ⭐⭐⭐⭐⭐ Very professional *by R***E on 15 November 2021* As expected. Is not very silent but not too loud either. Comes with all kinds of connections and is very professional. Im using it for my 3d printer and the wind power is just 👌🏻. Will probably replace the internal fan with another noctua too ### ⭐⭐⭐⭐⭐ Perfect for noisy TP-Link Switches *by D***N on 2 February 2022* I bought a new TP-Link Switch and it was ridiculously noisy. I mean, I get that its supposed to live in a server room but surely they could've done something to tone it down a bit. Two of these to replace the ones inside the switch have made it almost silent while still providing sufficient airflow. ## Frequently Bought Together - Noctua NF-A4x20 FLX, Premium Quiet Fan, 3-Pin (40x20mm, Brown) - Noctua NF-A4x10 FLX, Premium Quiet Fan, 3-Pin (40x10mm, Brown) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/348991265-noctua-nf-a4x20-40x40x20mm-flx-3-pin-5000rpm-case-fan](https://www.desertcart.sn/products/348991265-noctua-nf-a4x20-40x40x20mm-flx-3-pin-5000rpm-case-fan) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-09-14*
