End 1 USB A port End 2 small 3 pin / 4 pin case fan power adapter cable port Function Power 3-pin or 4-pin PC cooling fan directly from a USB Type-A port. Package Includes 2pcs USB to 3-Pin / 4-Pin fan power adapter cables Review: Work fine, just set fans to lowest speed - This USB to 3/4 pin connector works, but just be aware you will have no PWN control over the fans and they will be set to their lowest RPM setting, which can be a downside for some. But as long as you're aware of that, they work exactly as intended. Review: A must have for those who like to tinker and come up with their own solutions - These make for a fantastic addition to your collection of adapters. Especially if you like to come up with your own tricks to solving problems. Have an external drive dock that gets a little hot during a clone? Slap a random fan next to it and use one of these to power it up. We do it all the time for this since most docks don't have built-in fans to help compensate for such heat. We just reviewed an external fan for an Xbox that is pretty great, but you could also throw a normal (internal) PC fan on top of the console and use one of these to power it up with. As long as you choose a fan that is whisper-quiet, you'll forget that it is even on. There are so many uses for these, and a lot of them involve random projects that could benefit from a little air. Or, you can simply sit a fan on your desk, point it at your face, and plug it in for some instant cooling during the summer. Let your mind have fun. **If you have found our review helpful, please vote it as helpful below so we know.
