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.nz/products/167977979-argon-fan-hat-for-raspberry-pi-4-and-3-40mm](https://www.desertcart.nz/products/167977979-argon-fan-hat-for-raspberry-pi-4-and-3-40mm) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-08-07*
