Hi all. If I wanted to make my Nvidia XFX "Extreme Ed" 7800GTX in SLI run cooler what could I do, using only conventional methods ie not inluding liquid/water cooling or phase cooling. My card has a stock clock speed of 490mhz and is of the preoverclocked variety. The box on which my card came in says that they have used a really effecient and better cooling solution compared to a regular reference Nvidia 7800GTX card. I am not sure if this is true or not , but for the life of me i can't find any differences in the sink compared to a picture of a reference model, except for colour. My card runs idle at around 47-55 c in my current case and can go up to about 70-80c easily while playing FEAR. This game always makes a card go real hot, and so is a good game to test out cooling. I have seen these aftermarket graphic card heatsinks, from companies such as Zalman and Arctic, they have huge fans in the middle, so they look like they are effecient but I think they will make my card in to a dual slot card, which isn't ideal either. Anyway my point is , are my current temps particulary high for a XFX 490mhz 7800GTX or should I really try and get it lower somehow. Also would those after market heat sinks that I was talking about offer a big improvment or not , compared to what I have already got?
