Good day!
I have a problem understanding this software menu, The Smart Fan 5 Advanced Tab.
I mainly want to use this so I dont have to download additional software to manage my cooling. I want my computer to be so silent that I can barely hear it when idle, doing easy tasks as browsing, watching videos ect. And I want the fans to rev up when gaming, or stressing the computer with other demanding work. Think I now somehow have managed to get near to this goal.

I have an AIO Liquid cooler for my CPU. Its a Kraken x62, which is run by the software CAM from NZXT. I think this is best suited to take care of all cooling concerning the CPU. As there is many cables going out from the pump and also RGB on the pump. Therefore I think this should not be altered by another software.

There are 3 case fans beside the CPU AIO liquid cooler, and these needs controlling by some sort. I have them all connected to respective fan headers on the motherboard. In SIV Smart Fan 5, under the advanced tab, Im using a curve to set values for fan RPM to set temperatures.

I can select a temperature sensor from the motherboard, for each fan, which it is to take as a reference to controll RPM out from. I can also set fan position for each fan header, making it easier for me to know what fan im altering.

I have these sensors to pick from:

By testing how the sensors react and increase of temperature to stress, I have concluded that the only sensors that really react to stress testing, of CPU, Memory and GPU (Aida 64 Extreme) are the VRM MOS and CPU sensor.
Therefore, if I want my case fans to rev up, when the GPU, CPU and VRM MOS are under stress and their temperatures are increasing, I will need to select eighter the VRM MOS or the CPU sensor.
Selecting any of the other, with 0 to none temperature changes during stress, would only mean that my fans would run as if the computer were idle.

Im now using the VRM MOS sensor for all of the case fans, as that sensor show uniform increases in temperature aswell as reaching the highest temperature increase of all the sensors. The CPU increases by a big jump in temperature, but it also increases by almost the double. Although I think steady increase is better suited for controll of case fans, therefore I picked the VRM MOS sensor over the CPU.

This is how the curve Im using looks, and its the same for all the 3 case fans (System 1, System 2 and System 3 Pump)

Hope you read through it all, as its important to answer some of the questions Im having :)

1) Is there any good information or guides to this software (SIV) or the Smart Fan 5?
As I could't find any, neighter from manufacter nor any forums or videos.

2) What is the calibration button for, what does it do and why is it needed?


3) There is also Smart Fan 5 settings in the BIOS, what is this for, does it conflict with the Smart Fan 5 in windows, and can it change things you cant with the windows version?

4) Does the Smart Fan 5 software do anything to CPU cooling when I have the pump connected to the CPU header aswell as having the seperate CAM software to control that unit?

5) Im seeing as high as 5000 RPM if choosing the CPU fan in the Smart Fan 5, do this has to do with it adding up both pump and the radiator fans, as Smart Fan 5 can't understand whats connected to the CPU header unlike CAM which is the coolers own software?

6) Is an idle temperature of 30 - 40 C on the Ryzen 1600x CPU OC to 3.9 GHz normal?

7) Is a temperature of 55-65 C on the Ryzen 1600x CPU OC to 3.9 GHz normal/good when stress tested from Aida 64 extreme?

8) What does this table mean:
VFoV1gL.png


9) Why are some of the numbers in that table red?

10) Why is that table different than the System 1 fan? As you can see on System 2 fan the red text stop at 60 % where as on both System 1 and System 3 Pump fans, which are the same, the red text stops at 30 %

11) What does the Delta-Temperature-Interval (+-1) do and alter?


This is my rig:

Hoping someone with some knowledge and time in this software can give me some clues, and hoping this can help other new users struggeling with this program.

Thanks a bunch in advance!

Im having huge doubts regarding this software as well and I'm unable to find any documentation whatsoever. If you somehow understood how this works please let me know!

Well, it's not the best program I have encountered to say the least. Anyway, I have now set it up as you can see in the pictures:
ErjxYN4.png

System 1 is my upper back fan, in exhaust.

System 2 is my front intake fan.

System 3 Pump is my 2nd front intake fan.

The names of the fans in SIV (Syestem fan 1, 2 and 3 pump) is just reflecting the fan plug connectors on the motherboard (also called the fan headers) you have to manually inspect and look what fan is connected where, and then you can choose the placement in the program, to easier knowing what fan you are changing settings for. So I just followed the cable from every fan to the header, and then placed them correctly as you can see in SIV.

They are all set to take readings from the temperature of the VRM MOS sensor. This is due to I think this is the only correct sensor to use, if you are going to have an effective cooling, as this sensor temperature actually rises when the computer is beeing stressed, unlike some of the others. CPU I have a water cooler, with its own (better) program to alter those settings, so therefore I have not bothered to do anything with the CPU in SIV, as it wont be able to alter it anyways. I have a Kraken x62, and the program for that is called CAM, I like that a whole lot better. I dont run APP Centre, as I think the settings are saved to the motherboard, and dont need to have the program running for the settings to be in effect.

Hope this helps anyone other wondering! Although it should be noted, Gigabyte definetly should have a much bigger writeup and guides to how to use their programs correctly, explaining the features and also some reccomended settings.

Gotcha. Thanks for the info and the pictures, great help!

Just did a similar fan curve to yours and it seems to be working pretty solid. Thanks again!

I am trying to use this software to set-up and controls my fans. Can someone please advise me in a little more detail, how I can do this. I have a mixture of 3-pin and 4-pin fans.

I have been doing a lot of experimentation with fan speed settings in the BIOS ans using "Smart Fan 5" and believe I now now how this operates.

Firstly, all setting must be made as required in the "Smart Fan 5 Settings" page of the BIOS. These are what will initially be followed. If under the BIOS "Fan Speed Control" option, "Normal" is set, any fan speed options set in the "Smart Fan 5" application will override fan speed setting made in the BIOS for that option. I believe that this only applies to fan speed settings and not other setting but am still experimenting with this.

Any discussion, agreement or disagreement on this would be appreciated.

I will continue this discussion. I am playing around with smart fan myself. I have found that not using the desktop application works best, only changing setting in bios is the best way. Its a pain but if you only use the bios for setting your fans there is no conflict in the paramerers you set.

But if you are having problems with cooling your rig, it mau not be due to how your fan setting are it may be your fan intake and exhaust setup. I found my set up was configured with to much nefative pressure and I decreased the exhaust fans and my cooling issue went away. Having more cfm for positive pressure with new cool air forces warm air out better than having more exhaust fans to get hot air out. Once you have a proper fan setup then start working with smart fan to reduce power and noise at idle, or run full power during stress.

I have now got it working OK with some limitations with the application running. All setting in the BIOS and the application, with the exception of the fan curves, must be identical. The fan curves in the application then take precedence. All runs as it should except when waking up from sleep when it starts with very (some even zero) fan speeds.

Gigabyte tech support have sent me a beta BIOS to test so I will see if this helps.

Mine also starts with 0rpm on the fans. Im glad to hear you got it working. I finished mine today, with proper case fan balance and managed to get 5°C drop in temps by removing one fan at the top and allowing the primary exhaust fan to be the sole source for negative air pressure. I did leave one top fan at thw back of the case and set a fan curve so it will never go above 40% just to help remove residual heat from the cpu cooler.

Does anyone know if there any way to set the rated minimum and maximum speeds for each particular fan so that they show in the tables in "Smart Fan 5"? By default, they do not show correct maximum speeds (for me anyway!).

The new BIOS is in fact BIOS F7 and it still has the same problems in starting. I am still experimenting and am having discussion with tech support. I also have reduced my extract fans usage by setting the top two not to go over 30% except when temperatures get very high. There are certainly improvements with this.

As a matter of interest, does anyone know the purpose of the "RPM Fixed Mode" window in "Smart Fan 5 Advanced"?

Well I thought I was getting somewhere with Gigabyte online support on my problem in with fan speeds after recovering from "sleep", but no longer.

I have has discussing this with them over the past few weeks with information going backwards and forwards. I sent them copies of my fan curves among other things. Their latest response is for them to send me two screen-grabs of one of my fan curves. One, they say, they took before sleep and the other after recovering from sleep. They say that because both of the screen-grabs of the fan curve they have taken, are identical, there is no problem in recovering from sleep ..............................

Can we re-open this thread? I'm about to install my Gigabyte Z390 Pro Wifi and have had some concerns with fan management on my new build. Has any updates been issued that have answered some of the questions above?

Retr092, I was quite impressed with the clarity in your posts. Were you able to manage your case fans adequately? I've heard in other forums that it's best to only use the BIOS and to remove the Windows based Gigabyte application due to the demand it puts on your CPU even at idle.

Here are my build components: https://goo.gl/8zz42J

my Fans:
3 X Noctua NF-A12x25 PWM @ front panel (0.14A)
1 X Corsair ML140 Pro LED White PWM @ top rear (0.276A)
1 X NZXT RF-AF140C-RB (DC) @ rear (0.18A)

Are you guys still preferring only the VRM MOS temp sensor to trigger the curve?

Do i have to set to PWM in bios to get fan speeds to work ?

Thank you for your kind words. Yes, go ahead and ask questions. Sorry for my late reply, Im rarely in this site.
I was indeed able to manage my fans good. Ive also only used bios to alter the fan settings via the built in FAN settings in the Gigabyte bios. I have it set up like I posted here. And they run perfect around 40% speed on idle, which is a good area for both adequite cooling and low decible sound. Also they ramps up when the temperatures go up during loads. Which is also good, and the motherboard sensors are showing very good overall temps. Usually below 60 Deg C when td. Gaming. Under 40 Deg C. When surfing and so on. I do not use the SIV, Integrated program for handeling my motherboard settings or fans, only in bios.

Thanks for the follow up. So I've been running the fans quite well with the App Center, SIV and Fusion RGB. But yesterday I noticed that my monitors would't go to sleep at the time they were set to do so in Power Options of Windows 10. I realized that it was Gigabyte Fusion that was not allowing them to sleep. And even though I did not have it set to launch upon boot it would still run in the background. If it was running the monitors would not sleep. If I force closed it in Task Manager the monitors would sleep properly.

So I will be deleting gigabyte app center and all associated programs. Glad the fans can be managed in the BIOS without the faulty App Canter.

It may help to set them in the bios as you have stated. But this motherboard should be able to differentiate automatically and run the fans properly without you making these bios change. they have done this properly for my fans as I have a mix of PWM and 3 wire Voltage fans
