Ok, I got them. Something is wrong with your GPU. There might be a software problem between something and AMD's driver.
I uninstalled the drivers with DDU , and after that I download the newest driver from AMD. I tried to lower/off the shadows and still exists.
i) Have you checked if there's a newer bios available to this card?
ii) Have you uninstalled (using Revo Uninstaller, AMD Cleanup Tool, and DDU) the AMD chipset drivers and installed the lastest version?
iii) Have you tried to install just the drivers for your gpu without the Adrenalin? Device Manager > Right click on VGA > updated drivers (extract all the content from amd adrenalin package but skip the software installation... then you go manually in device manager and update it using the files extracted to the folder you set). You can do that and use ASUS GPU Tweak II to draw the fan curve.
iv) Is Windows fully updated?
v) Have you try to swap from auto to gen4 or gen3 pci express in bios settings?
vi) Try to uninstall any kind of monitoring software like msi afterburn and stuff like that.
Before to follow these steps, try to turn off any feature in adrenalin and see what happens.
