XFX 9800gt Overheating

[HoboBob24]

What's the ideal temperature for a 9800gt? Mine idles at ~71C with the fan at 100%, and runs at ~105C under load. Right now it's 84C with the fan at 50%, all according to EVGA Precision. It's not overclocked, 600/1500/900. I have two 80mm exhaust fans in the back of my case, an 80mm intake on the side, another 80 intake in that front, and lastly a final 80 intake on the top.
Yeah, I don't think it should be operating at boiling point. Is there anything that I could do to cool it down without spending much money?

how long have you had the card ? I bet you need to clean it.

Okay, I just cleaned it and did as you advised with the top fan, Mr. Ct. Right now it's idling at 70C with the fan at 30%. That's better than before, at least.

I've had it since Christmas, 2008, Mr. Shells.

When you cleaned the card did you take the heatsink all of the way off ?
