Review on 🌬️ WINSINN 80mm USB Fan 5V Dual Ball Bearing Brushless - Efficient Cooling for PC, CPU, Set-top Box, Router, DVR, PlayStation, Xbox - Pack of 2Pcs by Justin Live

The noise level of two fans together is zero. If I give 1 star for noise it's not fair to the seller because there is no noise. You don't need any instructions for the installation because it's very simple. The product stayed cool, hence no star for the temperature. If you are looking for the best quality USB fans at the lowest price on Amazon or eBay, this is the one you should buy. I am very cheap so I have been looking for about 10 hours a day for more than 1 week this is the lowest price with excellent quality and extremely impeccable customer service. BEST quality, LOWEST prices, durability and customer service.
