Is there a software (for nvidia controll panel) that would allowed me to control fan speed on my
GTX 980 ti (gigabyte)?
I`ve tried to find something but nothing so far.
have you gone into settings and chosen the fan tab? then select enable user defined automatic fan control you should be able to drag the lines to set your own fan curve. Also if you click on the little auto button right above the fan speed % slider you can force a constant speed.
