So, almost a year ago, I bought a brand new ATI Radeon 4830 HD 1GB version ( I know the model is older, but it is okay for me). Anyways, I live in Bosnia, and the teps in the last few days were almost 40C, which also mad my PC hot. The CPU is OK, never goes over 65C. However, the GPU on idle is 50C-55C. While gaming, the GPU goes over 80. So, my question is: are these temps normal, and should I worry? Bad thermal paste? The GPU is not OC'ed.
