So I recently replaced my GTX 550ti with a Zotac GTX 570. My 550 was nearly silent, even at full load. The new card however, seems to have a very loud. When it's at around 55%+ it gets noticeably louder. Maybe I'm just used to hearing no noise from my PC. Temps are good too, around 37C at idle and max 80C at full load. Thoughts?
