http://www.newegg.com/Product/Product.aspx?Item=N82E16814162113 I don't have anything to clean it with (air-dusters). I think it may be affecting my temps because when I first got the card it didn't hit 46c under load. Now its hitting 58 on stock, 70+ on overclock.
I've used a vacuum to clean my card then I just apply the thermal paste then its back to normal temps.
