If you look closely at the item photo, you'll see that it only has 2 wires running to the fan, 12v hot & ground. Plugging in this adaptor will cause the fan to run at full speed, which will be loud as heck. **Q: how long is the wire?** A: The cable is about 6-7 inches long. **Q: Does this deliver the full 12v to the molex?** A: Assuming the 3pin sources is 12v, yes. **Q: daisy chaining 5 4 pin molex fans, needing them to go to 3 pin male on motherboard, will this work?** A: It should but there could always be compatibility problems, Id just get one first and if it works then get more. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect connector for fans to motherboard *by R***O on 7 May 2026* Works Great!
