With just a one-line script, you'll have full functionality for the HAT, allowing you to do additional features such as rebooting the pi, and adjusting the fan speed of the single board computer. You can even program when the fan adjusts its speed, giving you full control over the HAT. Get ready to use this in any Raspberry Pi Case that offers HAT support, such as the Argon POLY+ or the Argon NEO. The best part is that this will work for the Raspberry Pi 4 B, the Raspberry Pi 3 B, and the Raspberry Pi 3 B+. ## Features - A Raspberry Pi Hat with a cooling fan that prevents overheating on the Raspberry Pi 3 B and Raspberry Pi 4 so that you can use the boards to your heart's content. - The Argon Pi 4 Fan HAT also comes with a power button that can be used to do safe shutdowns and reboots to the Pi; making it easy and safe to shutdown your boards. - The Raspberry Pi 4 Fan HAT is also PWM Controllable and Software controllable fan for full functionality and customizability while cooling your Pi Board. - The Raspberry Pi Fan HAT is highly usable and flexible in a variety of Pi Projects, especially for Raspberry Pi Servers where Raspberry Pis are stacked. - The Raspberry Pi 4 Argon Fan HAT easily fits in Official Raspberry Pi Cases and other Argon40 Cases such as the Argon NEO case and Argon POLY+ Vented Cases. ## Technical Specifications | Specification | Value | |---------------|-------| | Brand | Argon Forty | | Product Dimensions | 4 x 4 x 1 cm; 9.07 g | | Manufacturer reference | AR Fan HAT V1 | | Manufacturer | Argon Forty | | Processor Brand | Raspberry Pi | | Wireless Type | Bluetooth | | Voltage | 5 Volts (DC) | | Are Batteries Included | No | | Item Weight | 9.07 g | | Guaranteed software updates until | unknown | ## Product Details - **Brand:** Argon Forty - **Power connector type:** 4-Pin - **Voltage:** 5 Volts (DC) - **Cooling method:** Air - **Compatible devices:** Server - **Noise level:** 48 Decibels - **Material:** Plastic - **Maximum rotational speed:** 5E+3 RPM - **Air flow capacity:** 4.34 Cubic Feet Per Minute - **UPC:** 670924946939 ## Images ![Argon Fan HAT for Raspberry Pi 4 | 40mm Fan with Power Button | PWM and Software Controllable | Easy Setup - Image 1](https://m.media-amazon.com/images/I/71BhlTflFFL.jpg) ## Questions & Answers **Q: Can a hat be stacked on top of this one?** A: Physically, yes. The female GPIO header allows pins to pass through, so I used a header extender to stack this on top of a Innomaker sound DAC HAT. Looks great on top of their acrylic case. However, I'm still tracking down the pin usage to ensure that there are no conflicts between the two products (which led me here). So far, I've learned that the Argon One case uses GPIO pin #4 as an input for power on/off. Most likely, the fan HAT uses the same. **Q: What did you use to mount it? Did anyone get any mounting hardware?** A: I just pushed it down on the headers(pins). It is not meant to be mounted to the case. **Q: Can the fan control software be loaded/configured with a headless setup via ssh? Or do you have to have a monitor installed to configure the software?** A: ssh sould be fine to configure fan **Q: What is the dimension from the bottom of the gpio connector to the top of the fan?** A: Another Dimension issue; One screw holding the 40mm fan to the Argon board beside the blue speed leds had the nut hit my RPi4 heatsink, so i omit the screw. It depends on exactly how you stick on a heatsink, & what size it is. This has been No problem. ## Frequently Bought Together - Argon Fan HAT for Raspberry Pi 4 | 40mm Fan with Power Button | PWM and Software Controllable | Easy Setup - Argon NEO Raspberry Pi 4 Case | All Aluminum - Argon USB C Power Supply with Switch | Raspberry Pi 4 Power Supply --- ## 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.pt/products/211054697-argon-fan-hat-for-raspberry-pi-4-40mm-fan-power](https://www.desertcart.pt/products/211054697-argon-fan-hat-for-raspberry-pi-4-40mm-fan-power) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
