For example, if i slide that lowest (first) slider even 1% up and press apply - everything is broken. zero rpm can not be brought back, and even with 3rd party fan control software like speedfan (neutral one) the GPU will always go to 60c on 0 rpm, even if i completely slide GPU mhz, memory, and power limit to the lowest possible point. As long as i not touch it, its a cool 35c and works nice. I myself would like to set a lower temperature (more rpm) for some games, but yea, i better let it be. Maybe they will fix it at some point.
And by 60c i mean it would go up even more, but the fans kick in. I think the catalyst for it is the "zero rpm" option somehow. It breaks something in the driver, and the gpu goes in a nonstop loop by checking it, activity goes pretty high. I have no idea.
I can't see enough of your Wattman control panel to comment..but there has to be a setting for Temp like I posted. If you don't raise your Power Limit you will never get the performance the card was designed for. The default setting is a power saving/run quiet setting.
Take the time to read about Power limit on this older post AMD graphics performance
By mentioning the power limit i wanted to say that i lowered whatever i could, and still it did rise to 60c (till fans kick in) by just showing the desktop, not even
a browser and on lowest possible settings. As said, if i do not touch it, its absolutely fine on "0 rpm". As long i do not start gaming, no matter what i do it will stay below 38-40c. Performance wise the card is fine, can not complain about that.
Did you scroll all the way down in Wattman settings? 60c is the default setting...it's set to keep things quiet while you surf the web.
You don't have any 'Max' temperature setting at all?
Power limit controls the level of power sent to the GPU. Increasing this value can improve GPU performance by allowing the GPU to maintain its highest clock frequency (state 7).
Power Limit can be increased or reduced by +/- 20-100% and should be set to the maximum value when increasing GPU or Memory clock frequency.
NOTE! Power Limit % range is dependent on which GPU you are using.
I noticed this card has a dual Bios switch....maximum performance or quieter (noise level). Which one do you have it set to?
