How to slow a fan down

[PaulPaul]

One fan in my case which is the front in take spins at 1300rpm all the time which is loud and unnecessary.

Is there an easy way to slow this down? I have a MSI z87-g43 mobo

Thankyou

Check your BIOS for fan control settings.

I assume you have these plugged into your motherboard. If that is the case, have you checked the BIOS for a fan controller?

If your board has bios fan control, you could try to reduce the speed that way. If it doesn't, no worries because you can simply purchase a 5v or 7v fan adapter and that'd reduce the speed fo the fan.

get speedfan (http://www.almico.com/sfdownload.php). you won't be able to change your fans right away though. you have to go into settings and set the fan sensors to manual so you can control them through the software

Really?  I assume it's plugged directly into the PSU with a molex adapter (sounds like it)

I assumed the same thing honestly. Giving the benefit of the doubt maybe? I guess i worded that in hopes it was true.

7V adapter

you can get them for 2$ on amazon/ebay

so instead of 12V they only give 7V to the fan

so it will spin at about 60%

It is connected to the motherboard. In the aux1 fan header, 3 pin.

Then it should be possible to control it by either changing the settings in the BIOS or in Windows.  If all else fails, get one of those resistor wires shown above and do it "manually"

some people would suggest using low noise adapters ir PWN controller, but the thing with them is that they cost Money

 

if you want to be ghetto just put a pencil between the fan blades, that should slow it down plentfuly

wouldn't that be louder than just letting it run at full speed?  And possibly damage the fan?

if it's getting louder then you have to push it in deeper, eventualy the fan should become inaudible

 3 Pin fans can be MoBo (BIOS) controlled by the MoBo supplying them with less voltage if you can find no control in the BIOS for this fan speed you can reduce the voltage yourself either by plugging the fan into a controller or by putting a resistor in series with the fan supply (this in series resistor is easiest done by using one of the pre made voltage convertors shown above).

Sometimes (perhaps most famously by Noctua) these adaptor wires are called ULNA (ultra low noise adaptor) or LNA (low noise adaptor).

Just so I make sure we're imagining the same thing here, you're suggesting having a pencil slightly in the way of the fan blades so they rub on it as they go around, like having a card in the spokes of your bike?

yes

alternatively you can punch the pencil all the way trough fan blades so it jamms it and stops the fan from spinning

Nope, I assume,  he is talking about the pencil being shoved right in preventing the fan from turning.

lol ok I stand by all my comments then, I think that would probably be louder as the fan comes by and hits the pencil ~100 times a second, and could damage or wear out the fan blades and/or motor.

well, that would do the job, but then, just unplug it?  :wacko:

we take the hardware to the limit, push them over it, and run Commercials inbetween, records get broken, chips get burned, power supplies explode and the hardware just gives out

I thought you were going for the humour angle I did not realise you were serious (would imagine that the noise as the fan blades hit the pencil would be jarring).

yeah, me too - that's why I was questioning the suggestion

@Ryan_Vickers

   I have rather mucked up, I have conflated you and Dx member whose initial suggestion was 'Stick a pencil in it'.

 

Note to self pay more attention to who said what before posting.

Thankyou

When you do find your way into BIOS , if you have a 3-pin fan connected to your motherboard check that you have it set to DC, if its a 4-pin fan plugged into your motherboard header set to PWM mode.

If you have no fan controller, try the diy fan hub in my signature
