Chassis Fan Control

Hi Un4GiVeN78

To make Speedfan work you need to put a tick in Automatic Fan Speed honey

That's quite easy.
Who knew!!
Thanks

se fan and 1 120mm CPU fan in my system. 2 of them connect to 3 pin headers. The other one connects to the secondary 4 pin header, CPU fan to the CPU header. All of them, including the CPU fan which is 4 pin, are controlled by the BIOS settings and set to Silent which makes them run at around 800RPM, including the CPU fan. If the system starts to get hot the BIOS raises there speed accordingly. CPU first as that is what gets the hottest.

The BIOS lowers or raises the voltage supplied to the fans to increase or decrease there speed.

Yours might but if I'm reading the manual for Un4GiVeN78's motherboard, it will only control fans connected to the 4 pin headers,



which would leave any fans connected to either of the 3 pin headers running at full speed.

whereas yours (and mine for that matter) has Asus' Q-Fan option which does allow for. Also not to say it isn't possible, but do you really think that the PWR_FAN header would have any kind of fan control on it? Not sure that it would be a good idea to let anything other than the power supply itself regulate its fan. Then again when was the last time you saw a power supply that had its fan connected to the motherboard?

I tried to put a tick in Automatic Fan Speed and almost everything possible to control it, I guess it's hardware issue.

I must do something in the hardware before using that program to allow me controlling it.

Thank you guys <33

Well I'm really not sure what that PWR_FAN header if for. IMHO it certainly isn't for the power supply fan. They are all internal to the PSU with there own internal speed control and temp sensor.

Honestly I haven't seen a PSU with a external wire for fan control or power in a long time, if ever.

 

[Un4GiVeN78]

A 3 pin to 4 pin adapter won't allow for fan speed control for one very simple reason, there is no 4th wire from the fan itself which is what is needed for that to happen.

Not really. I have 3 120mm 3 pin case fan and 1 120mm CPU fan in my system. 2 of them connect to 3 pin headers. The other one connects to the secondary 4 pin header, CPU fan to the CPU header. All of them, including the CPU fan which is 4 pin, are controlled by the BIOS settings and set to Silent which makes them run at around 800RPM, including the CPU fan.

Hmm.. you're killing me guys :huh:

I can see from the M.B. manual that when Enabled allow system to run the FAN according system temp. It's already Enabled and running @ maximum speed which means my system temp. may be too hot so that the system run it @ full speed. Here's a screen shot of PC temp.

 

[Un4GiVeN78]

Or

maybe Enabled working like Disabled they both work @ max speed and it's all pretending

Bytheway, I think my PSU (OCZ 600 WATT) is frying because i tried to replace its fan because of noise coming from it, but the store guy told me that the stock fan is the best fan already and there's no any silent replacement and he gave me " AKAI BLUE " something like spray and when i used it on the PSU fan it made the sound much much louder.
Moreover SpeedFan showing i have 79 degree temp(look at the screen shot i sent earlier) on a piece of my PC and i think that's the PSU.

So, maybe the system fan is running @ max speed coz of it. idk

Thanks guys for your help i appreciate it all

Some PSU's have a fan header wire that connects to the motherboard so that you can monitor the PSU fan. It doesn't control the fan, just allows you to monitor it.

I bought a silverstone fan controller for my machine and my fathers machine to control the fans.

Hi ...
If you have knowledge of electronics - or know someone who has - you can make use of a resistor. Otherwise, you can use SpeedFan, but since the fan is connected to the motherboard. Remember to use 3 to 4 pin adapter and plug it in where shown below. Hope it helps!

Good luck with that.

Plug it directly into the motherboard... and if you've got the same BIOS version as me, you should have some full-on AI fan control settings. check out the photos attached for how I have my baby set up. (the fans are dead silent... two of them are 120mm's, one is 80mm)

Take note of the bottom settings, they affect ALL of my fans for some odd reason

My MoBo is also GigaByte

If you couldn't get Speedfan to work earlier, this may help....

Your BIOS is different, However my BIOS setting is like yours except I have "System Smart Fan Control" which i don't see in your photo.
I must have a FAN with 4 wires to be able to control the FAN by BIOS or whatever..

Thank you for your help.

Thank you it's good tutorial. Nice work.

 

[Un4GiVeN78]

I got it.
I can not control my 3 wires FAN until I buy a separate speed controller.
Or i can replace my fan with PWM FAN which allow speed controlling.

Thank you guys.luv ya all

 

[deanolfc]

any intake on my fan speed ect as i dont understand what it should be or anythink thanx

<3 pwm control


for my 140mm fan (at the front of my PC), I performed a hackjob. instead of the wires defaulting to 12v and neutral, I hooked them up to 5v and neutral. shaving 7v off is the best thing I've ever done. the turbine "frill" of the case looks nicer now its slower, and it doesn't sound like a wind-tunnel.

I tried to lower the percentage to 50% but it is not working and lower fan speed from the config. and still not working(look at the pic).

Did you configure Speedfan to work with your fans? Because you can't control them right off the bat.

Either I did it right or wrong it's not gonna work because my fan doesn't support speed controlling.
Thank you

Some motherboards will give you an option to control the fan through 4 wire Pulse Width Modulation or 3 wire by varying the voltage. On my MB I control several PWM fans through the BIOA and CPU 4 pin header (getting the voltage via PS molex) and several case fans through the BIOS varying the voltage on their 3 pin headers. If your MB/BIOS supports the latter, the fan doesn't have to support variable rate (except that it has to be able to spin up at the lowest voltage). Sounds like you don't have the latter option.
