I am having trouble with my RX 480 concerning temperature and load. I bought this rig in 10.2016 and the only changes made until today are two additional HDD's. I have two problems with my graphics card and one of them has been there since I bought it.
1. High temperature. The 480 is always between 70-77 °C hot... - in idle mode. Even when I'm only watching videos or writing stuff on Word, it's that hot. And it has never been any different. I do not understand why. When I'm playing games, it rises to 85ish, sometimes even more.
2. Load. This problem first occurred at the end of last year and I think it's the reason why my games are lagging. When I play CS:GO, I usually have between 150 and 250 fps. I'm using an Acer 144hz Monitor, that's why I was always comfortable with it. Now for some reason, the load rises completely to the top, like really the top. I'm talking about 99-100%. And whenever this happens, and recently it happens very often, my fps drop to a minimum, like 30-80. And when it does, it feels like I'm playing with 5 FPS. When this first happened I turned on the cooling system of my case and everything was fine. Now even turning on the cooling does not help. I am not sure what it is and how I can change it, but I think I need your help.
I had some major issues with the installation of the AMD drivers, so I decided to reinstall Win10 64-Bit, and it helped, but the problem with my graphics card did not change.
