Hello guys. I recently bought used but in very good condition Sapphire Nitro+ RX 480 4GB GPU. Thing is that Im satisfied with the card and its perfomance, but at the same time Im worried about my temps. the card on idle is staying at around 47-49 degrees with fans not spinning, while on gaming, temps stay around 58-70 degrees depending on GPU usage. The card doesnt go above 80 degrees on full load Funmark test(btw 10 min test). So, are these temps normal, or should go and open the card and change the thermal paste? Btw, GPU was never opened, but its reallyyyy clean and doesnt have any dust on fans or heatsink. Every answer well by appriciated. Thanks.
