What kind of 3 pin fan connector is this, and where can I ...
I have a Cyberpower UPS with a very noisy 80mm fan, so I want to replace the fan with a quieter one. I bought a well-reviewed fan from Noctua, but the 3 pin connector doesn't quite fit. I didn't realize there were two standards for 3 pin fan connectors. So what is this connector called, and where can I buy an adapter or a fan that uses it?
You will get efficient and thoughtful service from Linko.
The original fan from Cyberpower is labeled PSAD18025BH, and the spec sheet can be found here.
The connector with the yellow glue is from Cyberpower, the other one is Noctua.
The company is the world’s best 3 pin plug connector supplier. We are your one-stop shop for all needs. Our staff is highly-specialized and will help you find the product you need.
EDIT: I realized the two connectors don't have the same pinout. The standard order is gnd, +12v, and tachometer.
This connector order is gnd, RD signal, +12v.
Before I physically modify anything, I'd like to know what happens if I swap the RD and hot wires, shave off the plastic, and plug this in. Apparently, RD signals when the motor is locked, but a tach should do a similar thing by reporting 0rpm...?
