Fan edits not taking effect
Based on how the card is acting there apears some setting in the bios related to stock fan max rpm that is not in the editor, i want to edit this for using a different cooling solution than stock i changed the fan speeds and max rpm in the editor, but my fan speed will not go below 1000 rpm (this is 60%)
Are you sure your card can run with 0 RPM? Some of them doesn't have this "silent" option. Have you tried lower the RPM in Afterburner or something like that? Is it working?
The fan i had hooked up when i made this post is rated 400 RPM to 1500 RPM, using the vbios fan curve there is no way to have the card run at a lower speed it is like the card is setting a min target RPM (not pwm)
The card officially supports 0 RPM, but i have replaced the entire cooling solution so i wanted a new fan curve otherwise the fans will never spin up and cool the VRM, the min PWM % is ignored, it is set to 20% in the editor but the PWM output never goes below 30% even when the core is sub 30 this is when i have 0 RPM mode disabled in wattman, with the upgrades i made i have 2 fans, one does not support 0 RPM mode, and will run at 100% when it sees 0 on the PWM input, i would really like a checkbox to turn 0 RPM mode off in the vbios (i am not using crap fans that were not designed to run all the time)
due to what seems to be min rpm issue i have a fan splitter on the card and have a NF-A4x10 PWM fan hooked up to the sense wire so i get reasonable pwm % as that fan is rated 1000 PRM to 5000RPM, but the min PWM 20% is ignored, and it will not spin below 1500RPM my guess is there was a conflict between a max PWM and min RPM using the 400-1500rpm fan that let me get 1100rpm
There appears to be some fan controls that are not exposed in the editor, possibly the following
- 0 RPM mode: enable/disable
- Min FAN RPM (this must me overriding min PWM)
Here are the vBIOS files i have, along with tweaking stuff gigabyte_RX_580.zip

At present in Linux to get proper voltages i am using overclocking tools, so it does not hit the power limit and cranks out about 20W less and runs higher clock speeds (1411Mhz / 1131 mV; auto does 1340 / 1200 mV) for what ever reason my 580 nitro plus does not get 1.2v in linux on auto and gets the correct voltage
