I would say not to buy any of them if your not OC'ing. Your video card is capable of like ~100C temps, granted thats not good for the life of the card, but its able to tolerate it. Whats most likely happening is you fan is not spinning fast enough, I think speed fan will tell you what the fan speed is %. There are programs that let you change the fan speed, and its a good idea to speed it up to like 80% when playing games, then dropping it down to like 40% when not gaming, or to a point where its not audiable and still keeps the card cool. I have a evga card and there is a tool called evga precision tool that lets me overclock and modify the fan speed. The manufacturer of your card might also make one, but I think even speedfan will allow you to raise the fan speed!
