Video card overheating?

My computer's video card has been overheating for over a year now. Its only recently i have found a quick fix to that, by installing rivtuner and turning up fan speed. At first it worked wonders, but now it still overheats in games at 70% fan speed power. 100% fan speed doesnt make a difference now.Now im noticing that my video card overheats at lower temperatures, could this be because my video card is fried from before, so it wont live as long?



When my computer is idle, it's temperature is 53-54 degrees.

Under high powered games, it is between 70-77degrees. Before my computer would overheat at 80+, but now it does this about 75 degrees (i get these shooting polygons from buildings and characters.



I know it aint dust, because i regularly clean out my pc.|||if normal cooling doesn't work, it may be because of overclocking. You want to reduce the overclocking on your computer. However, this will probably reduce the performance of games.



Several thoughts:



1. Upgrading is an option. From your description, I would guess that your computer is a few years old now. Upgrading the video card could be an attractive and affordable option, and would improve your game performance.



2. Air flow: it is very important to make sure the air flow is positive. That means you have 3 types of places for air to move through your case: vents (no fans), exhausts (fans blow outwards) and intakes (fans blow in.) If all the fans are blowing in or all of them are blowing out, you are just trapping the air in the case. Make sure at least one fan is blowing in, and one is blowing out, or, that there is at least one vent where hot air can come out. Also, make sure vents are not blocked by a wall or desk, and that hot air has a place to move away from the computer. The worst thing to do is allow the hot air from the computer to be sucked back into the case.



3. Damaged parts: it is quite possible that you did damage the parts previously. In this case, there's really nothing you can do except start replacing parts, even if you did lower the chip tempertature later.|||Video cards in themselves run very hot because of there nature. Another thing to try is make sure it's in a slot with nothing around it leave a slot next to it empty if you can. Other than that the fan is a good thing I wouldn't work the fan to hard though If it's your regular fan to cool the comp off then it may burn out then you have bigger problems than your video card overheating. They also sell a fan that attaches in a PCI slot next to it just to keep the card cool.|||You can add more case fans--I have 3 in my pc. You can buy heat sinks for video cards--try Newegg or Pricewatch.com.

The reason is probably due to the graphics chipset itself. for example, the 8800GT is a very hot card, whereas the 9800GTX is a very cool one. It may also be because your case has bad airflow.|||are all fans working? is the card near any other devices that might bake it? is it really hot & humid where you have the comp? are you overclocking? those are the first things that come to mind.
