MSI Afterburner Fan Curve Issue / Help

[EKAN87]

Hello,

For some reason my Asus Rog Strix 2080 Ti fan curve with MSI Afterburner is messed up.

Below is a picture of my fan curve.

The fan speed stays within the limits (max 70% / lowest 22%), but the fan speed changes with each temperate change and not only when it should do based on the curve.

It was working fine yesterday and today after pressing the Performance button on the GPU it messed up, but I don’t think this is the issue that caused it.

Any ideas?

So apparently I didn't click on Performance mode button, that was the RGB lights toggle on/off on the GPU. Which means, why is my fan curve messed up?

I have tried everything... it just doesn't work.


I realised that the fan speed % stays within the minimum and maximum levels... hysteresis works... but for some reason it decides on it's on curve on when to go up and down... I've even switched between Performance/Quiet Modes, no change there... when I un-click the Auto button on the fan section the fan speed % doesn't move at all, only when it's on Auto but not on the curve %....I can manually set a fan speed to a static %... the same issue overall persists with GPU Tweak...I just don't know what to do, it baffles me.


All this happened after I pressed the RGB on/off button on the GPU.

I'll fish up something I wrote a little while ago to see if it's of any help to you. It deals with how the curve changes based on temperature among other things. It's very finicky right now.

As for fan control you have to actually get it looking like so in order to have your own fan profile active:

Which is counter-intuitive because Auto seems to be highlighted. But anyway that's how it works.

Thank you. I will try this and see what happens. It's just weird why this has happened... it makes no sense... it's like there is another curve somewhere which is overriding everything.

Note I have unlinked the Power Limit and Temperature Limit bars, and pushed up Temp Limit to max (92). That may be of help too if you haven't done that.

I've tried this, unfortunately it didn't work. My Afterburner look like yours as well... I just don't get, it doesn't follow the fan curve, it starts off correct then afterwards it increments per +1 temperature increase and not the curve's increase.

Try this: go to your custom fan profile window, and double click on an empty space on the graph. It should change to a stepped curve. Think that might do what you're aiming for.

You my sir, are a genius, it worked!! I can't believe it was so simple, looking at it... it makes complete sense!! Thank you a million times, I hope someone buys you at least a pint this weekend!! Thank you!!
