Can't get Fan Control to control GPU Fans

[BluestarP3D]

Setup Fan Control yesterday. Played some games for several hours, everything went well. However, I just noticed my fans were off a bit ago. Launched the app and noticed the temp was within my curve setting of 0 RPM when under 45*C.

Launched a light game to push the temps up a bit. Watched it climb to 60*C and the fans never kicked on.

Launched MSI Afterburner and it appears that it was controlling my fans. Kind of annoying considering I got Fan Control to control all my fans. I think I figured out how to disable the fan management, however I am not sure what is controlling the fan speed now. I have never set up fan controls in BIOS and I uninstalled the ASUS app that controlled my fans in the past (Xpert Fans).

This leads me to believe that MSI Afterburner might still be controlling the fans. The only step I haven't tried is uninstalling MSI Afterburner, but trying to avoid that as I use it for testing undervolt settings and OSD.

Really lost and confused at this point

EDIT: I uninstalled MSI Afterburner and it didn't change anything. At this point, i'm going to assume that when I disable FanControl's controlling, that it's the standard GPU factory settings taking over or something. I don't have any other fan control applications intalled.

First you should try to control them manually in FanControl to see if the control actually work.

I suspect your GPU bios has a minimum startup % around 50% (it is the case on my Strix 3090) So if you make a graph with a fan % below this minimum start up percentage the fans will just not run.

Anyhow, see if the fan start in manual mode and if they do, note the startup % and make that the minimum % in your graph for the temp you want the fans to actually run.

I think that worked! Thank you! New curve is below. The only question now... What app do you use for OSD/Undervolting? MSI Afterburner was nice, but now that i've uninstalled it and lost all settings... Perhaps I might try something different?

Also, is there any plans on allowing the fans to shut off under a certain temp? I recall ASUS Fan Xpert doing this, which was nice.

P.S. Jealous of the Strix 3090... I can't believe the prices dropped so soon, spent $500 more than the cost of one for my TUF 3080 Ti OC and now out of my return date :(

I use afterburner for undervolting. If I leave the fans on auto (in AB), it does not interfere with FanControl.

As for stopping the fans at a certain temp, create a point 0.1 degree above the temp you want your fan to stop and another right next to it, at the temp you want them to stop but at 0%. You will also need to create a 0% point at 20 degrree.

So ex. if you want you fans to stop at 45C:

-Point 1, 20C 0%
-Point 2, 45C 0%
-Point 3, 45.1C 50%

Note that this will create a situation where if the temperature start going up and down when near the selected start up temp, the fans will go on and off often. To compensate, I would suggest incresing the response time to 5 or 10 seconds. I would also suggest ticking the "hysteresis only apply on the way down" checkbox

Thank you! I'll play with it a bit. I forgot to mention though, when I was looking for the minimum startup time, once it shut off, I was not able to trigger the fan to start back up, even when adjusting to 100%. I had to use the fan identifier, otherwise I had to relaunch the app.

Wondering if this trick will bypass whatever is causing that. Left the house after I got this sorted out in my last comment. Will check later on.

I can't get it to show me controls at all. It detects there are 2 fans on my 6750xt but I can't seem to control them. I set it to a flat curve of 50% (the default one) but it just won't control the gpu fans.
Afterburner can control them with manual control when auto is off though

6750xt is not supported for controlling its fans.
