Graphics card fan speed should be set on automatic, since if you manually set it to low it can over heat. If you notice the game is running slow: Try changin the fan speed to manual and increase to about percent or a little higher, if you hear the fan speed up once you apply the changes (the fan sounds louder) the game you are playing may not be properly registering with whatever automatically controls the fan speeds (I am not a programmer, never studied it extensively) Fix slow performance in pc games or random games crashing for the computer PC Visit your graphics manufacturer’s homepage and find out if they have a free tool to change the speed of your FAN. (That is if you have a decent graphics card if not, then consider a custom built computer through someone local) EVGA has a tool but it is not very reliable (it requires human thinking assistance). When I first purchased my GTX 260 it would overheat in every game because the card didn’t recognize automatically to turn up the fan speed, shortly after I complained a half hearted fix came out (imagine that).. If you set it on manual it can still overheat if you do not set it high enough (mine just reached 110 celecius in COD black ops II because I had it on manually at 50% since the previous game i played didn’t slow it down entirely afterwords and the fan is rather anoying. .
