P35-DS4 fan problems

This may work. I don't know and I frankly don't care.

Fact is, Gigabyte recent motherboards have a SYS_FAN2 connection that doesn't work as it should and Gigabyte doesn't care.

It is not the job of the consumer to find solutions to a faulty motherboard feature and to me using other software or hardware to by-pass the problem is not a solution.

Deactivate Smart Fan in BIOS. Then install Speedfan 4.33, enter Configure go to Advanced tab, select IT8718F blah blah (first item in menu), make sure all three PWM modes are in Software controlled mode. That's all! Then choose if you want automatic or manual fan speed control.

Re: P35-DS4 fan problems

I use a Zalman ZM-MFC1 controller, they cost about 25$, look sharp and control 4 (more if you splice) fans, and also have 2 7/12V switches.

Just a thought for you. I also had sys_fan2 problems. Sometimes it would start slower then the system, but now is just fine. I have a friend who's board that header wont even Sense on, let alone run a fan. So I think it could be generally poor factory attention when building them I dunno?

Re: P35-DS4 fan problems

From my experience, only the 4 pin headers can be controlled with Speedfan. I needed to control 3 fans so I bought an adapter to connnect 2 fans to one header (both are the same fan type) and it works well.

I have one header dedicated to the CPU fan and the other header split as mentioned to move air through the case. BTW - all are 3 pin fans.

Re: P35-DS4 fan problems

that's why you pay 150% more over a basic board..to have a 1980s state of the art fan-control

Re: P35-DS4 fan problems

What the 2 3pin headers? Can they be controlled with SpeedFan?

Not to my knowledge.

Re: P35-DS4 fan problems

I am building a new PC with a P35-DS3R Rev 1.0 board. I thought it was bad that I had the older version, but given the last post, maybe I'm better off with this one! This MB has the same 4 fan connectors that most of these boards seem to have: CPU and SYS2 with 4pin and SYS1 and PWR with 3 pin. All my fans are only 3pin (non PWM) fans, but I would like to be able to control their speed from software (eg speedfan). I was very pleased to discover that the CPU fan connector can operate in 3pin/voltage variable speed mode as well has 4pin/PWM. Janus has already said that only the CPU fan header is speed controlled automatically by the bios, but can anyone tell me how many of the other fan connectors can be controlled from software, while using 3pin fans? va00 reported that they did get SYS2 to work properly with a PWM fan on a DS4. Will it also work with a 3pin fan, like CPU does, and on the DS3R board? What the 2 3pin headers? Can they be controlled with SpeedFan?

As for crippling, I've seen worse. My current PC is a pre-built retail PC (a mistake I won't be making again - I was too busy to build one at the time) and on that one the MB has the chip and circuitry to allow software fan speed control of one channel only, but the bios was programmed to continuously set it to one specific speed (not temp dependent - just constant). You could change the speed using speed fan, but the bios changed it back straight away. In Linux I wrote a script to continuously set the speed to what I wanted, faster than the bios could change it back :o) Not possible in windows, which I mostly use. Linux FTW!

Re: P35-DS4 fan problems

New reply from GGTS:

Please, not that the new series of DS3 and DS4 does not have this option.
It's the new design. and confirmed from our Bios engineer.
So the Bios setting of your MB are correct.

That still does not explain why a PWM fan does not work when it is connected to the SYS_FAN2.
If the bios settings are correct, then what is the use of having a 4-pin SYS_FAN2 on the motherboard if it cannot be used with a 4-pin fan and even if it should work, how is the fan to be controlled if there is no such option in the bios?

In other words, they crippled the new versions of these boards without telling the customers.

Re: P35-DS4 fan problems

I am really fed up with GGTS.
It took them 3 weeks to come up with this answer:

Indeed, after checking with our engineer it seems that the GA-EP35-DS3(rev. 2.1) does not support 3PIN smart fan that is why the option is not displayed.
It is circuit design.

Excuse me?

This was never about 3-pin connections, the SYS_FAN2 has a 4-pin connection.
I never suggested that SYS_FAN1 and PWR_FAN (both 3-pin connections) should support smart fan.

Bottom line: the SYS_FAN2 on the EP35-DS3 motherboard does not work with a 4-pin PWM fan and there is no smart fan option in the bios to control this fan (as you can see here in this picture of my Health Status page).
The P35-DS3 on the contrary does have this option (http://www.easycom.com.ua/data/mboar...236/img/b5.jpg).
These are exactly the same motherboards.
Why????

Sorry I Am Not In Ggts Team, So I Can Not Find Your Info Out.

Can You Mail Me? Include Bios Setup And How You Set Up Your Fan.

Re: P35-DS4 fan problems

Sorry, in my test didn't have issue with sys_fan2

give me a picture with your setup?

Picture of my bios?

The email ID's I have running at GGTS are 582695 and 584139 (picture of my bios can be found there).

Re: P35-DS4 fan problems

My sys_2 fan also does similar, I do control it now with a fan controller, but if I do not use the controller the fans starts about 10 seconds after everything else, and usually is ALOT slower.

Re: P35-DS4 fan problems

When is Janus going to reply something in this topic?

I was having the same discussion with GigaByte tech suppport and I have been waiting a week now for a reply to my last question...
Are they are out of ideas?

Re: P35-DS4 fan problems

Good news nicke2323. I hoped this issue will be resolved in future BIOS. We will see.. I'm curious what they intend to do, easytune-like control with temperature thresholds
and linear fan response would be ideal. I hope it will not be
another hard-coded settings, this way it is simply impossible to satisfy all of users.
