I have a zotac gtx 770, and it has been amazing. However on 4 occasions, after it being used for lets say 9+ hours straight, the fans emit a buzzing which is audible over the other fans. However this hasn't occurred when I have used it for a shorter period of time, but I have heard the buzzing come to a level that is louder than what the buzzing of ordinary fans is like but is some what satisfactory. What could be causing it? Is this a problem? Is it occuring due to being on for such long periods of time each day and gaming for most of it? Does it need to be replaced? I am going to university in September and will be using it a lot less so it wouldn't get to such a level to make the loud buzzing noise.
-edit- it has just occurred to me that this sound may have been made to occur more often due to me turning up the fan speeds on zotac firestorm
