Reduce my fan speed

[AbhiRockz]

I brought three Cooler Master Sickleflow 120mm led fans for my case .After installation the fans are noiser that i thought..So now i want to reduce the fan speed and make it silent.How can i reduce my fan speed.

If you have good mobo and if they are PWM fans you can do it from your mobo software if you have it installed. If not you can try to do it in BIOS... otherwise you will have to buy fan controller hardware

Even if theyre not pwm, you can change speeds via your mobo uefi.

Or just use a resistor eg http://www.newegg.com/Product/Product.aspx?Item=9SIA49A1KT4300

how to check if they are PWN fans...This is the fan i brought

pwm has 4 pin connectors. Voltage controlled ones (case fans) have 3 pin connectors. Yours is 3 pin.

^^ what he said

Well then how can i control the speed of my fan and make it silent atleast a bit.

go in the bios and there you should be able to see the fans.. lower the RPM

(Restart your PC, press DELETE button all the time when your PC restarts. It will go inside the bios)

What motherboard do you have ?

Start by reading what I posted -

but my fans are connected to PSU rather than Motherboard..I heard that fans connected to motherboard are the only onces that can be controlled by bios..

non pwn fans can also be controlled form bios..Well let me check ...If i buy fan controller will it help??

Aaah that's why they are so loud because they are working on full speed I guess... Usually your motherboards control them depending on how hot your components are or what are you doing (idling or are on load) and it would automatically speed them up or keep them very silent. Plug them on your motherboard instead of using the case

What motherboard do you have ?

well my motherboard is ASUS M5A97 R2.0

 

[i7Baby]

If you connected them to your psu, that's your choice. I connected mine to my motherboard so I can control speeds.

Use the resistors then.

If you have your fan set to automatic - clean your filters and make sure there's no dust inside the case. Dust can clog stuff up, increase heat inside the case and so it will set itself to spin faster to compensate. Maybe also consider what room/where you have it. Is it in direct sunlight? Are you in a particularly hot country? Is it a small room that can get too hot too quick?

If you do reduce the speed by the voltage, please stagger it. Reduce it by a small amount, use it for an hour and check temps and repeat until you have a happy medium. You don't want your computer overheating and maybe causing damage.

I suggest you to connected them to your motherboard. Your mobo will automatically control their speed. Registors will make additional mess in your case

You can connect up to 3 chasis fans on your motherboard

If I were you I would connect 2 in front/bottom or side panel of the case for air intake and 1 on the back for exhaust

But earlier you said i cannot connect to motherboard because my fans are not PWM...It has 3pin ..How can i connect my fans to motherboard??

 

[Proofy]

Well you will connect it to 3 pins and 1 will be unused 😛 It will work, doesn't matter if 1 pin is left unused...

 

[i7Baby]

I didn't say that.

I said "Even if theyre not pwm, you can change speeds via your mobo uefi."

ok i will connect nd wil try

i connect 3pin fan to 4pin on motherboard no problem wil occur right??

Right. No problem will occur.
