While I haven't used that cord I have used a whole lotta PC fans for various purposes and you can run them forever on pretty much any power source. I hardwired a 10 year old PC power supply a while ago for the 2 PC fans I was using for a small experimental box I made (got nothing better to do? try building a box in under an hour with whats in your house at the time :thumbsup.
Pretty much what I'm saying is that PC fans are versatile and use very, very little power and I see no reason why that cord shouldn't meet your needs.

BTW-If execution matches the design you could have a money setup.
