20.2.2 fan PWM% setting not going lower than 26%

I have a Sapphire RX 5700XT Nitro +, and under 20.2.1 I had adjusted my fan PWM setting to be a constant 12% up to a temp of 60C as it was whisper quiet at this speed and much less annoying than having the Fan Stop feature enabled, as the Nitro's heat sink is just not big enough to passively keep 5700 XT GPU cool enough to stop its temp steadily climbing up to the point where the fans come on and ramp up to 1300 rpm (in silent vBios mode) which is really quite annoying. I saved my modified fan speed and a stable undervolt that I had worked out as a Profile.

I upgraded to 20.2.2, but when I imported my saved Profile, I discovered that 20.2.2 no longer allows me to set a fan PWM% lower than 26%. The heat sink on my Nitro + is much bigger than the reference card's and can keep my GPU temp below 50 deg C for desktop use at a fan PWM of 12%. I thought that this might be an issue with my imported Profile, so I did a complete DDU clean and installed 20.2.2 fresh. I tried to set new, fresh fan PWM profile, but once again found that 20.2.2 won't allow a fan PWM% lower than 26%.

Please AMD, let me set the same fan profile that I could set in 20.2.1.

With regard to your issue, this is the response I have received from Driver Engineering.

Some Radeon owners may have noticed that with our latest Adrenalin 2020 Edition version 20.2.2 posting, the lowest allowable PWM percentage in fan tuning has been modified or increased versus previous drivers. This change is the result of revised logic that now correctly sets the minimum fan PWM percentage to the minimum limit defined by the product’s VBIOS. As well, Adrenalin 2020 Edition version 20.2.2 fixes an error in the Advanced Fan Control user interface whereby a lower limit PWM percentage may have been incorrectly reported in Radeon Software, when in fact the fan was running at the higher minimum PWM defined by the product’s VBIOS. It is expected that with these fixes, users will have a lowest selectable point on their fan curve that conforms to the PWM limit defined in their specific product’s VBIOS.

I don't disagree it would be nice if you could control the fans the way you want.

The RX580 used to turn the fans off under no load. When the 2019 drivers came out they mad it so if you use a manual fan setting there is no way the fans ever cut off.

One way some get around this if you don't mind losing the Radeon Settings and related software is to only load the AMD driver part. 

You can do this by letting the driver unpack to the AMD folder, then cancel the install.

Then from device manage choose your GPU and update the driver by pointing it to the AMD folder and it only installs the driver.

Then you can just control your fan how you like with Afterburner or Trixx for instance. Just don't use those 3rd party utilities and Radeon Settings as they are known to conflict.

hi friends. i am facing the same problem as you. i bought two rx 5500xt , the first one was chinese version and the second one is dataland which i think is original. and i sell the first one because  i cant control the fans, and bought the second one when i thought there will be no problem of fan in it but i face the same problem beside both of them miireport the fan speed to any software i use like msiafterburner or asus gpu tweak which is the only software that can spin the fans at 20% but there is still noise blowing my head becauqe the unit is next to me .

i tried all the versions since the old ones till the new; and edit the user settings which the adrenalin cant accept lower than 35% !!! and i tried the pro version with no luck  and even search of a way to flash my card to edit the minumum llowed speed of fand nut they mention that  the xt is not included yet .

so i am adding my voice to the voice of my friend to amd company to let us control the fans . iam guessing we are adults and know what we are doing.its not logical that the old cards are free to control and the new ones their speed of fans are not even reported to windows !!!

thanks for hearing me, and sorry for taking so long, but i did not find where to find a solution to my problem necause i cant play any game with such noise.
