Fans if you could would be around 50% at like 65 and 100% by 78. Anyways here is a link to my specific card stock bios! https://www.techpowerup.com/vgabios/168096/evga-gtx970-4096-150108-2

Thank you much mate! thumb.gif
I just modded the bios you linked to me how you wanted. -no oc software needet
-core clock is set to 1506mhz with boost disabled
-mem clock is set to 3901mhz
-with my voltage table config , the card should run at ~1.260V note that software isnt reporting anything measured from the card nobody really knows what its showing but you could measure it with
a multimeter if you really wanted
-TDP and 3D base clock is untouched
-TDP is set to 280W (full 100%-means slider in MSI afterburner goes down but not up 100% is max.) -im sure thats overkill as hell but I´m not familiar with 970 power consumption at all
even if you were able to hit 280W, your pcie slot,8pin and 6pin would handle that easily

Now on to the tricky part -fans
I never tweaked fan control in bios cuz I always used bios mod in combination with oc software -oc software offers way better fan control
In the bios , fan control is marked as "experimental" the reason is that its not easy at all
I went through some calculations and set 2180RPM at 60c after 60c the fan RPM keeps growing until it should hit 100% at 78c <-with that "fan curve" your card wont come near 78c
-normally, I would test it myself but my 980ti is on water
Everything I just mentioned above should work but I dont know how your card behaves below 65c
I suspect it will start the fans at 60 and "slowly" turn RPM up to 2180 as the temperature goes 61-62-63-64-65 <-- "ideal" scenario
The card could also completely igonore fans below 65c and just go from 0RPM to 2180RPM right as it hit 65c <--dont think the card will behave like this but idk

After you flashed the bios, MONITOR TEMPS AND FAN SPEED and run a benchmark.Focus on potential artifacting (if I did something wrong on voltage table -I didnt but still confirm the OC is stable)
It would be nice if you could tell me how your fans behave and if my suspected "ideal" scenario was correct
If I was correct, it should be possible to let the fans start at a lower temperature like 55c if you wanted to
In case you notice something not working as it should ,I´ll find what I did wrong and try fix it.

*minimum RPM could be addet too
