Had some PC fans I had not used and decided to make a dry box for my cake decorating business. This little USB connector was perfect. Arrived super fast and well packaged.
Had a box full of pc fans and bought this to test the fans. Much easier then using a working pc to test with. Product works great, would be even better if it could tell you the rpm, maybe the next gen of the product.
I use it to cool down an external HDD in my PC sata slot. Works great
