I ordered a 5v speed controller for a tiny USB fan I use in a Paludarium. The price was very good, the speed controller works very well and was exactly what I needed. The shipping was so fast I couldn’t believe it! I will definitely be ordering from Coolerguys again for my Aquarium builds.

Works perfectly
I use it to control the speed of a USB fan on my desk. This gadget works great and I can run the fan both at very slow speeds and at full speed.
