i do notice it does come on by itself after it gets hot.
it just worries me that it does that.
anyway to force it to come on?
If this is the "problem", it's not a problem
It's completely normal, the manufacturers put fan curve to only turn on fans when GPU is hot
You can easily set fans on manual mode on Afterburner
Look, you have to go to fan speed slider, click on Auto to deactivate the auto feature, set the percentage you want, and click on check button, that's all, your fans will start rotating at the speed you put
