Review on 🌀 Noctua NF-A4x20 5V Premium Quiet Fan (5V Version) – Efficient Cooling with 3-Pin Connector, 40x20mm, in Brown by Sam Carter

After getting the 12v version I got low cooling due to the fact that the Yahboom fan hat I put on was only 5v. After the replacement I met loads of cool air almost immediately. The Yahboom is programmed to use only 30% power at 40°C and even at 30°C I could still feel an airflow. And above all, be silent. I'll do some stress testing, but I doubt this little beast will let me down
