Title: Controlling PWM fan
Post by: malum on April 29, 2011, 12:23:08 am
I wanted to know if there is an application that is verified to work with the
Gigabyte 880ga-ud3h rev 3.0 motherboard.

I would like to manually control the exhaust fan on my case.

I have heard some good things about Speedfan but does it work with my mobo?

Thank you!

Can't see why speedfan wouldn't work, best way it to install it + give it a try. Not sure if Easytune lets u play with fan speeds? Other than that its a fan controller, or a converter so the fan runs on 7v instrad of 12v hence making slower + quieter

Speedfan + fan controllers will allow you to change the speed almost "on the fly"

Speedfan does not work for me. I'm gonna try Easytune to see if it does allow fan control.

Thanx for the reply!

Hi there,

Been struggling to find some links for this issue  (they really need to improve the search function on the forum) however you might like to like at these threads:

Although they are not referring to your motherboard the problem seems to be the same. I spent ages playing around with Speedfan and Easytune in an effort to gain some control over fans connected to the motherboard headers on my own system and failed miserably.

Yeah I have had no luck...

Oh well...This really should be something gigabyte should include to make their boards more appealing.

For now I will be building a PWM controller.

I have a GA-E350N-USB3 board that is nice for a home theatre setup but I'm not getting control of the fans and that bad.
Anyone tryed it with this board?
I'm using speedfan...

Easy tune did allow me to control my CPU PWM fan speeds. But not my Sys fan speeds for the PWM fan I have on the first header.

Like someone else mentioned a fan controller seems to be the best option.

Or if you have a good silent aftermarket cooler like a Noctua you could use a regular
header for that and then use the PWM cpu header for the other fan , or with the use of a
pwm y-cable multiple fans as long as they don't go past the amperage allowed for that Cpu fan header.

The dedicated fan controller is by far the best choice and should last you many years. Much safer than piggybacking fans on the motherboard header etc.

From my experience I know that SpeedFan doesnt adjust fan speed  in all mobos.

In Gigabyte mobos we have PWM function even with 3-pins, right?

Point is to control our fans automatically. Zero rpm when temp is too low and more rpm when heat increases.
Do u know any program which does this?

Yes I understand what you are saying and that was why I suggested using a  fan controller. The Lamptron Touch FCT will automatically control up to six fans at once.

Are you sure this device doesnot work manually but auto?
Title: Re: Controlling PWM fan

Lamptron Fan Controller Touch Black Anodized FC0092H

This is one that he was suggesting because it has has the option for either manual or automatic.
 At least I think it is the one he was referring to.

Yes that seems like the one and it can be set to a manual level or automatic or a mixture of them both. ;)

I guess u need to put a cable sensor in... where exactly? under the heatsink?

Is there any device with 1 or 2 buttons only? ;D

Hi

You can't actually put it under the heatsink as that would interfer with the interface between the two. You will just have to attach it as close as possible and make sure it is firmly fixed.

 I know you can control your fan speed by a setting in my bios under fan control. Or you can do the cool and quiet thing.
  Or try this  http://www.newegg.com/Product/Product.aspx?Item=N82E16835220014 Its not expencive and it comes with a controler.

It is a good idea to bundle a controller with the fan and other extras. Only trouble is if you wanted several fans to be controlled you would soon run out of drive bays.

So, all people who use such devices(multi fan controllers) they put their cable sencors... where exactly?

Unfortunately cool&quiet cannot stop the fan(zero rpm).
There are many fans with controller, but point is the auto function. A smart fan that will spin only when necessary. Its not comfortable to adjust it all the time ourselves. If we forget?

Most fans wouldn't be able to stop altogether as they need at least 5v and many 7v to start up again. This is why most controllers only spin the fan down to a low level not actually stop it.

Note that in the mobo I have(ga-ma770t-ud3) the cpu fan I connect(500rpm and installed at the back side of case, not at the cpu ) will stay still when I start pc. It will start moving after a while, when heat come :)
