Raspberry Pi 3 Fan Holder

As shown in Christopher Barnatt's video series, located at the bottom of this page, the Raspberry Pi 3 requires a minimum of one heat sink combined with an active cooler to operate at maximum power without experiencing any overheating issues. To address this need, I created these brackets to securely hold a 40x40x10mm fan. The design was inspired by Toolson's Fanholders for the Ramps1.4 (CC BY NC). If you use a 5V fan, such as the Sunon MB40100V2-000U-A99, it is possible to power the fan using the Pi's pins 2 and 6, as demonstrated in Barnatt's video. I ran Barnatt's bash script on my Raspberry Pi3 B v1.2 once without the fan, only with a small aluminum heat sink. I also ran it once with the 40mm fan, specifically a MB40101V2-000U-A99, which is the same model I recommend, except for its 12V voltage rating. To verify the results and ensure identical ambient temperatures of 20°C, I performed the benchmark test five times without the fan and five times with it. The difference was astonishing, with a temperature increase of over 30°C after just five runs, and a consistent temperature reading of 47.2°C.
