RX480 - Fan crazy at 2560x1440(VSR)

Hi, guys!

I'm having a bug when I use 2560x1440 (virtual super resolution) and 17.3.3 driver in games. The fan is completely unstable and does not conform to Wattman settings.
For example: I set the fan on Wattman to reach maximum 2700rpm and maintain the temperature between 75º and 85ºC. When I am playing at the resolution stated above, the fan is getting stuck at 2800 ~ 2900rpm and the temperature is around 50ºC, meaning the fan is being used to the maximum without any need. I need to restart the computer for the fan to return to normal.
At resolution 1920x1080 this does not happen and the fan obeys the configuration of Wattman. I reinstalled the drivers (clean installation) and it did not work. There seems to be some bug in the drivers when using the 2560x1440 (maybe because the virtual super resolution??).

 

Any help would be appreciated.

My Settings:
i7 3770k
12Gb RAM
Sapphire Nitro + RX480 8Gb and 17.3.3 drivers
Windows 10 build 14393.953 (64bit)
