I run 4 of my fans off of 8 D batteries = 12 V. I didnt want them running all the time and wanted to take my comp out easily (fans arent in or on comp), so using comp power was out of question. Rat Shack sells those battery packs for $1.99. Takes 4 D batteries and spits out 6v. Hook 2 of those together and you have 12v. Works well so far...
I'm a ghost...email me if you have any questions on my old setup
I think even if you have around 13-14 V while driving this would not dammage the fan. If you feel not good by connecting the fan directly take a cheap one so that it doesn't matter if it brakes.
Ah yes forgot - Have some equipment at home which runs 24h/day and that needs a fan - This fan is connected to a 13,2V PSU - Until today - no problems

Running a fan at a slightly higher voltage (14vdc) shouldn't cause any problems, as people have said. If its a cheap fan, it could shorten its lifespan, but when you consider how simple of a mechanism and how cheap a fan is, whats to loose?

speaking of fans i found a stupid trick the other day while messing with one of those clear fans with the l.e.d's in it if you put it unplugged i front of another fan or something else that will spin the blades fast enough it generates enough power to power the l.e.d's like i said stupid trick but hey
