don't worry, if the fan dies, you can still buy an aftermarket cooler
the problem might be that you'd reject hot air in the case, though (that is if you use a normal case and not a crate)
but you can find all-in-one watercooling blocks for gpus and use them on an exhaust of the case to prevent rebreathing hot air
if you can't find any and it's too expencive, you can allways use some cpu all-in-one watercooling solutions if it's any cheaper and check for a tutorial on youtube

it's weird.. ran both on solo, they freeze
i run them for poolmining, no problems

hey, i've had problems with the v0.2 and v0.3 releases on my gtx 660ti

works fine on v0.1, but not with the newer versions...
the miner seems to just freeze in place not using any gpu power, and whenever i shut the window it says that it stopped working
i'm solo-mining fugecoins
is it a problem with the binary?
is the new version exclusive to some types of gpu's?
