I have a EVGA GeForce GT610 that I use for my PC. It runs minecraft perfectly at 50-70 FPS, just the issue is that it starts to make weird artifacts on my screen or glitch with the frames as in putting in unfinished textures that look really awkward. I monitered my temperature and it stays steady at 75.0 Celsius under Minecraft but when I close it, the card runs at around 49.0 Celsius. Is there a way I can increase the fan speed or something? Or is that temperature normal? The GPU is still at stock clocks and stock voltage so it's right from the manufacturer condition.
