Just out of curiosity, why are you looking for an 80x50? Apart from what size hole (80mm) the fan needs to fit, the thickness of a fan really does not tell you much (although most fans of that size do move quite a bit of air). There are two numbers that most of us pay attention to.
CFM stands for cubic feet per minute and tells you how much air the fan moves when not loaded. Given two identical fans, one used for case cooling will move more air than one trying to push air through a densly pinned (or finned) heatsink.
dBa is a measure of how loud the fan is. Some peolpe cannot stand a fan that is rated over about 30 dBa and some people just take the loudest fan they can get because they push lots of air. What fan you can live with is entirely subjective.
To compare a bunch of fans by sound you can Go to this link. If you already have a fan that you have dBa info on, you can adjust your speaker volume so that a similar fan closely matches your existing equiptment. If not, you can at least get an idea of the relative differences.
Personally, I use the Sanyo Denki 80x32 fans and I find that my computer is quiter than the desk fan that I in the corner.
