Review on 🌀 High-Speed 24V Hydraulic Bearing Brushless 30mm Fan - WINSINN 3010 (Pack of 5Pcs) by Muleme Anderson

Small fans come in handy when you're constantly doing something odd. I use one on a hot V6 clone and the others are used in various projects. They draw very little power, so a dedicated, fast, and dirty little boost controller will get me up to 24V easily. They move enough air to be efficient, but can be a bit noisy depending on the environment and application. Smaller fans need to spin faster to create airflow, so that's to be expected.
