PWM Controllable and Software controllable fan for full functionality and customizability Review: Perfect in every way - The Argon Fan Hat is a low profile, programmable speed fan, for RaspPi. It is nicely built, and takes power off the GPIO connector; no ugly wire for power. All GPIO connections are passed through so that adding another hat would be easy. The speed control is programmable, according to temperature and allows full on, or various % of speed to be set at 3 different user selected temperature points. The fan is very quiet, and kicks in and out almost imperceptably. I bought 3 and could not be more pleased. The construction is superb and it installs easily. They provide a link for the control software, which can be installed without problems. A very nice addition for working Pis. Review: Great Pi 4 fan - Not using this fan for overclocking my Pi 4 but just need something to keep the heat down during the long hot summer months since the Pi 4 computer stays in the garage where temps can get up to around 104F in the summer. This fan doesn't come with any mounting hardware but I already have a kit and made it work along with mounting a MMDVM hat on to of the fan. Also the nice thing about this fan kit is that it has a pass thru GPIO header so you can mount whatever boards you need on top of the fan and not have to worry about loosing the 2 GPIO pins for power. I didn't modify the config file but just mount it and left it alone. And so far in the heat, the operating temp is a cool 92 F degrees. This should prolong the lifespan on the Pi 4 computer in the heat. Installation again was easy as long you have the mounting hardware for it. As for connectivity it has the pass thru GPIO and the fan pulls power from the two pins (see photos for a better explanation. Lastly if you're using a passive heat sink, you probably have to get those GPIO spacers so it clears the heat sink. ## Features - Efficient Cooling for Raspberry Pi Designed with a 40mm cooling fan, the Argon Fan HAT helps prevent overheating on Raspberry Pi 4 and Raspberry Pi 3 boards, keeping your system stable during heavy workloads like servers, media centers, and development projects. - PWM & Software-Controlled Fan Speed The fan supports PWM and software temperature control, allowing you to automatically adjust fan speed based on CPU temperature for quieter and more efficient cooling. - Integrated Power Button Includes a multi-function power button that supports safe shutdown, reboot, and forced shutdown, giving your Raspberry Pi a convenient and safe power management solution. - Simple One-Line Installation Get started quickly with a single command installation script that enables fan control and button functions, making setup easy even for beginner Raspberry Pi users. - Flexible for Raspberry Pi Projects Compact HAT design leaves room for heatsinks and accessories, making it ideal for Raspberry Pi servers, clusters, development systems, and DIY electronics projects. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07Y9LFP1J | | Air Flow Capacity | 4.34 Cubic Feet Per Minute | | Best Sellers Rank | #165 in Computer CPU Cooling Fans | | Brand | Argon Forty | | Brand Name | Argon Forty | | Compatible Devices | Server | | Cooling Method | Air | | Customer Reviews | 4.5 out of 5 stars 762 Reviews | | Item Weight | 0.02 Pounds | | Manufacturer | Argon Forty | | Material | Plastic | | Material Type | Plastic | | Maximum Rotational Speed | 5000 RPM | | Noise Level | 48 Decibels | | Number of Items | 1 | | Part Number | AR Fan HAT V1 | | Power Connector Type | 2x20 pin header | | UPC | 670924946939 | | Unit Count | 1.0 Count | ## Product Details - **Air Flow Capacity:** 4.34 Cubic Feet Per Minute - **Brand:** Argon Forty - **Compatible Devices:** Server - **Cooling Method:** Air - **Manufacturer:** Argon Forty - **Material:** Plastic - **Noise Level:** 48 Decibels - **Power Connector Type:** 2x20 pin header - **UPC:** 670924946939 - **Voltage:** 5 Volts (DC) ## Images ![Argon Fan HAT for Raspberry Pi 4 & Pi 3 | 40mm PWM Cooling Fan with Power Button | Software Temperature Control | Safe Shutdown & Reboot | Easy 1-Line Setup | Compatible with Pi Cases - Image 1](https://m.media-amazon.com/images/I/71BhlTflFFL.jpg) ![Argon Fan HAT for Raspberry Pi 4 & Pi 3 | 40mm PWM Cooling Fan with Power Button | Software Temperature Control | Safe Shutdown & Reboot | Easy 1-Line Setup | Compatible with Pi Cases - Image 2](https://m.media-amazon.com/images/I/81zpkFPEK2L.jpg) ![Argon Fan HAT for Raspberry Pi 4 & Pi 3 | 40mm PWM Cooling Fan with Power Button | Software Temperature Control | Safe Shutdown & Reboot | Easy 1-Line Setup | Compatible with Pi Cases - Image 3](https://m.media-amazon.com/images/I/71ZMCviNowL.jpg) ![Argon Fan HAT for Raspberry Pi 4 & Pi 3 | 40mm PWM Cooling Fan with Power Button | Software Temperature Control | Safe Shutdown & Reboot | Easy 1-Line Setup | Compatible with Pi Cases - Image 4](https://m.media-amazon.com/images/I/71aRVCwrr9L.jpg) ![Argon Fan HAT for Raspberry Pi 4 & Pi 3 | 40mm PWM Cooling Fan with Power Button | Software Temperature Control | Safe Shutdown & Reboot | Easy 1-Line Setup | Compatible with Pi Cases - Image 5](https://m.media-amazon.com/images/I/71IP6EpPrFL.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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect in every way *by D***H on October 7, 2024* The Argon Fan Hat is a low profile, programmable speed fan, for RaspPi.

They are also configurable via software on the Raspberry Pi that allows you to set what temp the fan will turn on and also what speed it will run. If you choose not use the software at all, the fan will just stay on a run at the 50% speed. Just doing this chopped off about 10 degrees on my devices, so I think I'll just leave that setting as is. I have three units running all at the same time and while I can hear the fans when up close, they aren't super annoying. It wouldn't bother me anyway since I have these devices running in a dedicated network rack, so it's not something I ever have to be close to. ## 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.com.om/products/167977979-argon-fan-hat-for-raspberry-pi-4-and-pi-3](https://www.desertcart.com.om/products/167977979-argon-fan-hat-for-raspberry-pi-4-and-pi-3) --- *Product available on Desertcart Oman* *Store origin: OM* *Last updated: 2026-06-09*
