yup it does look nifty but at the end of the day gfx cards come with a fan for a reason its not there to look pretty

if they needed to have extra cooling i think the manafactor would put one on there ,i know plenty ppls that put lights water cooling etc.. on there puters and for what? they dont play high end games/sims etc.. the lights look nice but,
is your computer getting that hot? if it is what wrong with it ?
if not what is the reason behind your worry of cooling ?
if you like things to look pretty then go for it ...
if you like a good machine buy more for it like a higher end gfx card ,if you say buy three fans there 90$ extra on a card....
there are many places that you will find that will tell you need this and this but really if your puter is screeming along fine then it works just that ...
