Googalize "25k PWM Arduino code". The real issue is trying to find data specs on the PWM IC that Noctua uses. Googalize "Noctua PWM white paper" and you'll get all the info you need on their PWM specs. Target frequency is 25kHz but the acceptable range is 21kHz to 28kHz. GOOD LUCK. **Q: Is there a 5vdc pwm temperature controller for this fan? been searching, but can't find.** A: No its controlled by the motherboard. I threw away the usb adapter cable, If it was used to power the fan, since usb is 5v, I would expect it to run at full speed. I used my fan on an NVIDIA NANO Single board computer **Q: how long is the cable, from the fan all the way to the usb connector? i want to put this in a small area, so looking for one with a very short cable** A: 40cm. **Q: is there a usb version of the noctua 40x20 5v fan** A: No, there is no USB specific version available. But the kit does include a USB Type A to 4-pin female adapter cable. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Le silence *by R***R on 28 February 2026* Très très très silencieux, un peu léger pour le refroidissement mais c'est parfait pour mes besoins ### ⭐⭐⭐⭐⭐ Silencioso *by D***N on 20 January 2026* Increíble cómo algo tan pequeño puede mover tanto aire sin sonar como un mosquito enfadado.

This fan achieved all those goals and more! It came with a USB adapter, which left the cable pretty long - too long to go a few cm into a USB port on the side of a Pi - so I cut the wires and soldered the USB connector directly on to the wires leaving the fan housing - very simple to do thanks to the nice design from Noctua and it's happily doing its job of keeping a Raspberry Pi nice and cool. Obviously at 5v it doesn't have a lot of oomph, but for its size and how silent it is, it does move a good amount of air. Impressed and recommended for smaller projects such as Raspberry Pi based builds! ## Frequently Bought Together - Noctua NF-A4x10 5V PWM, Premium Quiet Fan with USB Power Adaptor Cable, 4-Pin, 5V Version (40x10mm, Brown) - Noctua NF-A4x10 FLX, Premium Quiet Fan, 3-Pin (40x10mm, Brown) - Easycargo 4pcs 40mm Black Fan Grill/Guard with Screws + Nuts (4 Pack) --- ## 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.ni/products/585361753-noctua-nf-a4x10-5v-pwm](https://www.desertcart.ni/products/585361753-noctua-nf-a4x10-5v-pwm) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-07-17*
