Hello to everyone,as another user tell on this topic: https://rog.asus.com/forum/showthrea...Tweak-Problems I also have the same issue with my board,so only one fan spin with thermal regulation and the second stays at 20%.Also with asus gpu tweak,afterburner, or other software only one fan can be regulated,the second stays at 20%.I have tried in the same system with an asus hd 7970 direct cu II top,and the two fans are controlled very well with afterburner or with the Drivers utility,with no problems.
i have tried several gpu tweaking utility,but the second fan stays always at a low rpm,15/20%. with the latest asus gpu tweak,the slider of the second fan makes no effect on the fan,and the tabs "Auto/Manual/User define" are gray and are unusable. with the 7970 dcu II top i have no problem to regulate the fan. the button on the pcb for the 100% works normally.
Maybe the second fan starts to work when the temperature rise over a certain level?
Ok,will be done, but,in the cd of the card there is a special version of the asus gpu tweak?or not? Another resolution can be to disassemble the two 100mm fan and install other fans and connect them to a molex connector.it is possible?its the same thing when installing a waterblock...
With asus gpu tweak II release 1.1.1 i have the control of the second fan but only using the "user defined curve".At the moment is a very good setup,with the second fan blowing at the same rpm of the first fan. *I think that also the drivers must be Not the latest r17 but something from the 2014/2015. I will try and post the result.*
