Review on 🌀 3-Speed Controller USB Quiet Fan (120mm) – Ideal for AV Receivers and Wi-Fi Routers – 2 Pack by April Smith

Two piece USB fan won't turn on when first turned on or after a power outage. I was hoping to use it in a sealed case that turns on when I turn on my computer. , but it has to be turned on manually every time. It's fairly quiet and seems to move a decent amount of air, but won't turn on after a power outage, rendering this product useless to me and invalidating many uses for this fan. .(edit) I ended up putting solder lines on the button as shown in the picture which will automatically start the fans at high power once power is applied. I've now connected it to my computer and it cools the desk case it's in perfectly.
