3 Pin Fan connecting to 4 Pin MoBo.

[Gamingpc78]

Hi All,

My case is NZXT Phantom

http://www.amazon.com/dp/B003WE9WQO/

My MoBo is GIGABYTE GA-Z87X-UD4H LGA 1150

http://www.newegg.com/Product/Produc...82E16813128617

The case fans are 3 Pin and Mobo is 4 Pin.

How do I connect them?

And What is the Best option?

1. Have them connected with PSW and let them run at full speed.

2 Or have MoBo control the Fan speed?

And What connector I need to buy ?

NZXT Phantom Case have Fan speed controllers.

Thanks In Advance.

You plug them in just leaving the PWM pin open. This is typical.

Almost your same exact posting and the solution.

The fan connector heads have notches that allow them to align with the onboard connector in only one orientation.

uhm.....your case has a fan speed controller. Wouldn't you want to plug them into that?

Was trying to control Fan with system software. Then I decided to use case fan controller.

system software usually only works with 4 pin fans.

I have found it best to just get quiet fans at what you need and let them run.

Speed control and stuff is interesting at first, but proves to be high maintenance if you are needing high cfm at times.

larger the fan is usually the quieter fan, rotates slower but pushes more air, can leave on 100%
