So whilst poking around in my computer I managed to snap one of the fan blades on my graphics card's fan. It is a Palit 8800GT. Here is a pic demonstrating what happened:
Please note that this is not my card but a pic off the internet of a card which is similar enough to mine.My heatsink and everything is fine and the fan still works but once it goes above 70% it starts making a horrible sound. Ideally I'd like to just replace the fan and nothing else e,g, heatsink etc.
Does anyone have any advice or suggestions.
