This is my point. Or at least Gigabyte should cooperate with thrid party software markers (SpeedFan) to allow them to control fans properly. The latest version of Speedfan seems to work fine with some Asus Z97 boards but not yet with Gigabyte z97 because the author does not have the datasheet of the controller...

Yep... they only need to respect what they show as a feature.

I'd reported the SIV problems again. It's a pain to deal with giga customer support. They ask for questions I cant answer.. "how many days takes the system to forget the settings?" I dont know... how can I predict such an unstable software?

Check the source code, it's your software!

About that "the system forgets the settings" issue, shouldn't that be the fault of the BIOS? I thought you (want to) run it without any software getting loaded at Windows start-up, right?

I'm imagining there's the chip on the board that gets the sensor input and then controls the fans and it has some default rules for that. When you turn on the machine and the board starts to boot, the BIOS has your fan control scheme saved somewhere and writes it into that chip. When it eventually stops working right after a few days, the BIOS for some reason forgot the settings and goes back to the default ones.

If it works like that, what you need isn't just a new SIV version, you also need a new BIOS.

Hi, I think it´s just a SIV problem. For SIV fan control, you need to let fan settings in bios set to "normal", which is what bios default comes with.

SIV is loaded at windows startup (there is no option to set that on siv, but looks like it´s done by default), even a gigabyte process is loaded at windows startup (maybe this is the responsible for applying fan settings), but I´d checked this process and always starts fine, even when the settings are forgiven.

Also, there is a fan profile 1, 2, 3, 4 xml on SIV folder, which are modified every time you edit fan curves, I´d tried to set this files as read only... but didnt help. SIV it´s just ignoring this files when it wants.

I just bought a Gigabyte X99-Gaming G1 and am having difficulty controlling my fan speeds on a Corsair H110 cooler. I can't get Smart Fan Advanced to allow my CPU fans to go below about 725RPM, which is far too noisy and unnecessary for idle workloads. The 1400MM radiator fans are plugged into the CPU_FAN header, while the pump is plugged into CPU_OPT header.

Does anybody know how to get the proper fan speed to stick? You can see that I chose 100RPM, but it always goes to 726RPM after I hit apply. It's driving me nuts!! Here's a screenshot of my SIV/Smart Fan Advanced:

deepor · Sep 12, 2014

That should be exactly what your fans do when they get a 0% PWM signal sent, those 700 RPM being their minimum speed. What you can try to do to force them to go even slower is using voltage control instead of PWM. It's very likely that you can do that in the BIOS. If it works, switching it over means that the board will send a 100% PWM signal on the PWM pin (that's pin number four), and will instead regulate the voltage on the 12V pin (that's pin number two).

On voltage control, your fans will run as if they were three-pin fans instead of PWM four-pin fans. When you set 0% speed in the software, the board will send the fan 0V and the fan will be off. For 100% it will be 12V. You will need to find out at what percentage/voltage the fan starts turning and use that as the minimum speed in the software.

trihy · Sep 12, 2014

Yes, using 4 pin and corsair h100 fans, you can´t go lower than 700rpm, that´s a limitation of corsair fans.

Also, are you sure you can hear the fans at 700rpm? When I was using an h100, the pump noise was intolerable for me, but fan was inaudible. Maybe lowering pump voltage will make it silent.

acc3d · Sep 12, 2014

Thanks deepor and trihy for the suggestions. The pump on my H110 is inaudible, but those fans at ~700RPM are still driving me nuts (my machine is in a really quiet room). I think it's because of the turbulence created by the radiator and grille on the top of my case.

I noticed that the 140mm fans did indeed go slower than ~700RPM when I clicked calibrate on Smart Fan Advance...it just won't let me set the values any lower.

trihy · Sep 16, 2014

Have you read any review for that fans? SIV let set my fans even at 0rpm. But when I was using a corsair fan, lowest was 1000rpm, even the reviews tell this.

After 30 responses from the same ticket...

"Answer:
You must use 4 pin fan to support PWM otherwise it will not be able to accept the changes"

I can´t get gigabyte team to get coherent.

I´d sent a latest feedback and if no logic answer, I´ll give up.

trihy · Sep 20, 2014

Well.. they released a new version of SIV.

It's worst. It doesnt even remember any setting without opening after every reboot.

It's the worst piece of software I'd ever tried.

If you need manual fan control, avoid gigabyte, period.

acc3d · Sep 23, 2014

I can also confirm that the new version of SIV (B14.0905.2) does not to load SmartFan+ profiles upon reboot. I have to open up SIV, change a value, and hit apply EVERY TIME I RESTART!

This is extremely annoying, on top of the fact that the BIOS doesn't really offer precise fan control. I'm starting to wish I hadn't spent $350 on this x99 Gaming-G1 motherboard if they can't even profide reasonable fan controls.

I guess we should report it to Gigabyte Support instead of complaining on the forums huh?

trihy · Sep 23, 2014

Yes, please, report to esupport.gigabyte.com

Other way they wont fix this software.

Latest build is a joke, it´s worst than ever.

I´d reported several times but they said they cannot reproduce the problem on his lab

I have 30 responses from them on this problem without any solution. That´s why I´d started to complain on forums. They dont like bad rep.

So, as more users reports this problem, maybe they will take some time to really test.

Trihy, I just wanted to say thanks for posting this. I am looking for a new non-ASUS motherboard and onboard fan control is important to me.

I was pretty happy with control using ASUS but want to avoid them for other reasons. I was considering Gigabyte, but will avoid it for now. For someone who DOES want good onboard fan control, does anybody have any recommendations for brand? (other than ASUS- while I love their features I'm hesitant to give them anymore money with track record I have with them).

trihy · Sep 25, 2014

Hi

Well... if I can help any user, it till be fine for me.

First time, I´d avoided asus cause their fan control has a limitation that was not good for me.

Asus xpert fan let you set the fan curves like you want, even creating cool relations between temps and fans... like raising system fans rpm according to cpu temp instead system temp.Problem with asus, it that at 75C fans will hit 100% speed. There is no way to avoid this limitation.

Gigabyte let you set 100% at 90+C. As an hptc user, I dont care if cpu hit 80 or 85C from time to time. That´s why I´d been a gigabyte user since z77, until now, that they f*c*d up all their fan control software.

Dont know about other manufacturers.

Hope other users share their experiences.

I was looking at msi, they have great boards atm, but there is no mention of any fan control at all. Some users said it will let you control only cpu fan but not system fans. Really don´t know.

I have been looking at them too. pics of their software seem to be limited to cpu fan although there is a single button for "system fan". Seems limited either way. I'm doing tons of research now. I'll post here if I find an update.

Your best bet is to choose a SpeedFan (http://www.almico.com/speedfan.php) compatible motherboard. You could adjust fan speeds to either GPU or CPU temps. Sadly. Gigabyte does not cooperate to allow their controller data sheet to be shared .... This was my last Gigabyte motherboard.

Nice. That may help a lot with my decision. Here is direct link to motherboard list if it helps:

trihy · Sep 26, 2014

Yes, support for speedfan is a little hit&miss, specially on newer boards.

But when it works, it´s great, also a little harder to setup than most fan controllers, but not by much.

Hard to believe fan control is not a mandatory feature for motherboards. 2014 and still cant get full control of a 3/4 pin fans

TheChris2233 · Sep 26, 2014

Do you know if gigabyte z77 still has fan control? Thanks to insight from another member, it occurred to me that I might could find a used z77 board and resolve my problem that way.

DeXel · Sep 26, 2014

Only 2 headers on most of their Z77 boards. PWM is on CPU_FAN header only.
