Fan Questions...

[Zackey_TNT]

First Question i was told if two fans set up like they are in pull pull (see photo) they are more likely to die? My shop keeper told me not to install the blue fan there as the CPU fan Died it was a coolermaster stock hyper evo 212 cooler

Second Question my fan has a molex 4 pin and a 3 pin fan header should i plug both of them in? does it give more speed/power? will it blow my computer up?

Third Question Why cant i slow or speed up my fans? I only have 3 pin fan headers but no matter what program i use none of the fans will slow/speed up when commanded to. Its an ASUS F2A55-M LK plus

Do NOT plug a fan that has multiple inputs in. Looking at that, it's bound to have something pop.

Plug it into the motherboard, it will mean that you can regulate the speed it works at through the BIOS, no it will not make your pc go BoOm

 

but before that, what fan is it

I believe one is for the LEDs and the other for the fan itself.

First off its a "deep cool" fan that is all i know

second off The LED's turn on no matter what one i use

Use the motherboard connector, is it fully functioning?

Yea but its really slow (CPU fan at 1600 RPM Blue fan at 1300RPM)

Can you turn it up in the BIOS?

Have not tried that yet but the programs that came with the mother bored (AI suit from asus) cant change the speed if that fails what hope does the BIOS have?

[Zackey_TNT]

Also pull pull one fan at a lower speed one at a higher makes both more likely to fail? is this true?

[MLG Doge]

I'm not sure, but it is worth a try

 

And im pretty sure that is just a rumour.

Those aren't "slow" speed FYI. Slow would be under 1000rpm. Those could even be max speeds and propably are since its normal for mobos to run fans at full.

 

Answers to original questions:

1) It won't kill anything to use pull-pull. But it won't do any good for you either. Unless you mean that rear fan is pulling out of case and CPU fan is pulling out from heatsink. Then its ok and called push and pull. Not push-pull as they aren't connected to same thing (case/heatsink).

2) Refer to fan manual. Some LED fans use external connector for LED but usually its combined. Only use one or fan motor will burn out.

3) Check how fan headers are controlled in BIOS. Since you are using 3pins, they should be marked "voltage" controlled.

Thank you very much i will look into it Both fans are moveing air out the same hole (the back)

Righty then nothing in bios no control over the Fans what so ever.

OK. And Speedfan isn't working either? AMD has some own thing for CPU which should be automatic if you can't control it. But for case fans you might need to get separed controller or limit their speed with regulators.

[gilm0re3]

You need 4pin pwn fans to control yohr speed when plugged into the mobo,and no it won't kaboom your rig

You can also control fan speed on 3 pin fans, but you have to be controlling the speed via voltage instead of pulse width modulation.

well yeah i know that but you need a mobo which needs that functionality 

 

Yup, it may be that mobo is too old to have voltage based control over casefans. The CPU fan is more buzzling since every board has basic control since Socket A.
