Review on 💻 upHere U803 80mm Silent USB Fan - Ideal for Computers, PS4, TV Boxes, and AV Cabinets by Brian Messerly

My biggest dislike for these fans is that they don't move enough air to really warrant anything. I have them under my reef tank to keep airflow through my sump and also to cool my Kessil tuna flora. But unfortunately they don't move enough air to help with that. So I have to keep the doors wide open for now. I used a whole saw and cut a hole big enough in the side of the stand to allow them to draw in as much cold air as possible from the outside in and it still doesn't work. Many Thanks
