Like many of you here in this forum and elsewhere I have tried in vain to create a custom fan profile for my 980 Ti Strix using GPU Tweak 2. I could create the profile and it would work until I either rebooted or shut down GPU Tweak. On restart the default profile would be back.
I had almost given up when I spotted 4 .ini files in the Asus tweak directory (C:\Program Files (x86)\ASUS\GPU TweakII). The first file, InitData_Card1.ini was for my card, the 980Ti Strix. Going through the file I noticed some settings for fan control. The default profile waits until the card starts to get hot and then attempts to cool the card with a very modest duty cycle (fan RPM). My card would throttle and temps were close to 80C using the default fan profile.
(Default fansetting shown below from InitData_Card1.ini )
[fansetting]
DefStartTemp=64
DefStartFanduty=33
IsHybridFan=1
IsSupportFanPolicyTable=1
IsSupportFanControl_AMD=0
TempPoint1=61
FandutyPoint1=33
TempPoint2=84
FandutyPoint2=54
TempPoint3=90
FandutyPoint3=65
TempPoint4=99
FandutyPoint4=100
TempPoint5=100
FandutyPoint5=100
I found that when I added the values that I wanted the fan profile changed. Not only did it change but it now sticks, it doesn’t lose my settings after a reboot anymore. (See my changes below).
[fansetting]
DefStartTemp=30
DefStartFanduty=33
IsHybridFan=1
IsSupportFanPolicyTable=1
IsSupportFanControl_AMD=0
TempPoint1=30
FandutyPoint1=33
TempPoint2=50

TempPoint3=60

TempPoint4=70

This profile starts the fan at 30C and ramps it up gradually thru 80C, I seldom see temps higher than 65c after prolonged gaming sessions and no throttling. Just backup your ini file, change your values to the profile you want copy and overwrite the file in the Asus Tweak directory, reboot and test. If you look at the GUI for the custom fan profile it will still show the “old quite hot fan curve” but testing with GPU-Z and the Tweak monitoring utility will prove that the fans are operating the way you specified the ini file.
This worked for me and I hope it helps others who are looking for a fix. It’s not perfect but it is a good work around. Make sure and use the ini file that is specific to your card.
