Heyup guys, got my nice x1900xt but looked into properly overclocking it recently and noticed other people are getting temperatures of about 70 when overclocked, even with the standard cooler. Well mine sits at around 90-95 slightly underclocked, which i'd assumed was normal up until now. I bought it from the members market on here, is it safe to assume the heatsink was removed and re-fitted incorrectly?
