If you want something small and isn't going to be noisy then get the zalman VF900. I own one and they can handle hotter cards just fine and they are fairly small compared to some of the large coolers and is all copper. The fan quiet and it adds a few aesthetic qualities to the system if yours is windowed. It will help improve overclocking if temps are high on the stock cooler and they are easy to clean. Very easy to leave it at that. They are expensive but in the long run you will be thankful to own such a nice cooler as they can be used on most cards from both nvidia and ati. It is a dual slot and you want a third slot for better air flow to the fan but that is all.
