Review on Powerful Pack of 4Pcs WINSINN 60mm High-Speed Fan - 12V Brushless 6010 60x10mm by Brandon Ball

I saw a YouTube video recommending them for Raspberry Pi 4 even though they are 12V and the Pi should have a 5V fan. The old 5V fan was like an airplane with the window open. It's so quiet here that I can hear my neighbors' thoughts. The caveat is that this fan is much larger than a 5V fan and won't fit in most Pi cases. As you can see from my photo I tether it to my Pi. It looks like hell but sounds like heaven. It all goes in an arcade cabinet so I don't care what it looks like. Highly recommended if you don't mind the ugliness.
