Front case 4 1/2" fan replacement

Hi I have this question today, I want to replace the 4 1/2" fan in front of my case, the original one is making a bit of noise at startup.

The original fan is a Coolermaster 12v 0.16 amps and it's connected through molex power directly, it has no control but it's a very quiet fan.

The replacement fan I have here is a Coolermaster also, 12v but that one is .37 amps, and when I connect it through Molex, it like a airplane propeller, it's very noisy and way too strong for nothing.

This is it here:


So I was told these fans can be connected into the mother directly to control their speed and.. in hope of getting much lower RPM just like my 0.16 amps.. to get a quiet computer. But the wire itself is simply too short to reach any of the CPU_Fan connectors.. and it's not even the same type of connector. Those on the motherboard are 4 pins and my coolermaster fan is a 3 pins connector.

My CPU is connected on #2 CPU_fan (Left) and logically the front case fan would go on #2 (right).. or #2 Fan 1 bellow the CPU. Do you use some kind of converter, it needs an extension cord too. What should I do to have a success with this.

Thanks

A 3-pin fan can plug directly into a 4-pin socket.

Two of the pins provide power to the fan, the 3rd provides an RPM pulse to the motherboard to read the speed. The 4th pin is for PWM speed control.

Robot Check

Extension Cable

And yes, the three pin cable will plug into the 4 pin jack.

Ok ok thanks everyone for these answers. So I might try to hook up the 0.36 amps fan again tonight.. Do you know by chance if it's usually possible to limit the RPM inside the bios menu if it's plugged in "Cha_Fan2"

I know there are a couple of options for the fans in the ASUS b360M-A but I am not sure if i can set a maximum RPM, I really want the computer to be quiet as much as possible.

You should purchase fan utilizing a sleeve bearing it cost less and deliver low noise output levels, especially at lower speeds, compared to fans that use ball bearings.

Ok, do you have a model in mind?

the store they have Corsair fans, Cougar Vortex FW120 and FB120, I need to search them up on google first to see the specs., the other one is a Antec Spark 120 RGB which has hydraulic bearings, I can also get a Noctua which i don't know the model.

The "Cha_Fan2" is for a Chassis Fan [think Case Fan], I'd think the motherboard should have come with a program with the controls for it, some have a program included for managing the BIOS users' settings from within Windows, my ASUS does.

The controls are there inside the but I just can't remember if there is one to limit the RPM of the fans. I'll know tonight.

No i don't have model in my mind.

I just spoke with a local store, he told me to forget the wire extension and simply splice the original wire and weld an extension to it.. that,s another logical idea... i will try that first with my .36amps coolermaster and test the bios control.

If the noise level is ok with bios control.. I'll use that simply.
