Question 1

Will this work with 3 pin fans?

Accepted Answer

Yes, I used it with two 3-pin fans. The plugs still fit and there is just one empty pin on the end.

Question 2

Are both of the male sides of the connector 4 pin or is one of them 3 pin?

Accepted Answer

All are four pin. This is what you would use to run two fans off of one fan connection on your motherboard.

Question 3

If I connect this splitter to a Motherboards 4 pin PWM connector and connect 2, 3 Pin Chassis fans to the Adaptor will the connected 3 Pin fans speed be controlled by the speed signal coming off the 4 Pin Motherboard connector ???

Accepted Answer

According to my knowledge a 2 pin fan will run at full speed all the time as it has just red and black power wires. A 3 pin fan speed is adjusted by the motherboard according to temperature. You may have settings for that in your bios. The extra pins on the 4 pin fan header just won't be connected. The 4th pin is there for a more refined method of controlling fan speed but you need a 4 pin fan for that to work.
