A graphics card will slow down if it gets too hot. Increasing fan speed (adjusting the curve higher / left) keeps the card cooler, but louder. The card will usually self overclock a little bit by itself. (My 980ti advertised a 1139 MHz boost clock, but runs at 1380mhz without me changing anything).

Is there a thread where new members can get the required 10 posts (before being allowed to send PMs) without annoying people / spamming? I assume just being a contributing member is the ideal method of getting 10 posts, but am curious if there is a spam thread.
