Ok since everyone (including OP) forgot how to have a proper tech problem thread, let me put you back on track.
First of all, what model is your graphics card? Is it single slot or double slot?
With Ati, all you need is the Catalyst control panel, you should be able to control the fan from the overclocking menu (don’t try to overclock though as it will most definitely kill your card)…
If you’ve got an Nvidia graphics card, I’m pretty sure you need a program like rivatuner or nTune to control the fan speed. Either way, when you’re gaming, you can safely set the fan on 100% to save your card from burning down.
Have you ever opened your computer before? If not, turn it off, remove the panel on the left side, remove the graphics card and try to remove as much dust from the fan as you can.
Put the card back (don’t close your computer) and try to play a game. If you continue to get high temps, you should buy a new cooler+fan assembly for your GPU, just make sure it’s compatible, they’re not all the same.
Just keeping your computer open will cool down the temperature inside, the only downside is the ugly look, but honestly who cares?
