Overclocking fans?

I was interested in this a few weeks ago.
The object here is to achieve a potential difference higher than 12v. 12v being +12v minus 0v - the difference.
So u need to tap a negative voltage from somewhere and span it with the +12v to give u a bigger difference than 0v does.
I didnt look any further as to what negative options u have.

Thanks, I got the stock fans in a GIGABYTE 3D Aurora and the go at max 1000RPM and don't move much air so I have to have no wondow on the side to allow more sir to circulate and cool Dual SLI GTX 280s. But the problem should soon be solved as I'm going to get a watercooling kit for Xmas and watercool my CPU and the GTX 280s.
My next question is do you think I need fans faster than 1000RPM with watercooling?

I just bought this one 
I don't think a new case is really an option I could take as i'm a bit short of cash. This is the Gigabyte 3D Aurora 570 (renamed to SUMO 5115)
gigabyte.com.tw/Products/Chassis/Products_Spec.aspx?ProductID=2827
It says it water cooling ready. But that could be for older kits.
( Sorry about the link not being clickable but it says I have to have made 15 posts or more until I can do that.)

From what I can tell, the entirety of the "water cooling capabilities" are two rubber grommets at the back allowing an external radiator to be connected.
As for the broken link, it needs www at the start of the url, or the gigabyte site rejects it =P [also suffering from too low post count syndrome]

I unintentionally done this once, I hooked up the side fan on my A+ case (a 22cm thing) to my akasa fan controller but also to the case fan controller, I can't remember why.
It caught fire.
Quiet amusing, I was turning the controller up and just noticed that more smoke came out the side vents. About then I realised ideally no smoke should be coming out those.
After looking inside no major damage, the black cable going to my akasa fan controller burned out, just exposed wire and it was the wire insulation that caught fire.
So probably not a good idea if you end up putting too much in

"About then I realised ideally no smoke should be coming out those." Whahaha that literally made me LOL
But tbh I do not think overvolting fans has any use. Like GavX mentioned you quite dramatically decrease the life span of the fans (to 0 hours, to be a bit more precise) and for a few quid you can buy a highspeed fan which you can undervolt when you want it to be quiet.

As Jim said, over-volting fans is not recommended. For a good bit more cfm for not a lot of pennies, i'd recommend Xilence as they push (on paper!
) 68cfm at 1400rpm as are very quiet. Excellent fans for thermochill rad's. If using the like's of black ice rad's, use the same or go for fans that run faster (2000rpm) which should get you about 80-90 cfm and still not making your ears bleed. i.e, yate loons, silenx etc...
You only need a case thats big enough to house the rads you want. Lots of variables here as it will depend on how many loops, what you're cooling, what you can afford etc etc. You can also mount rad's externally, i.e, on the back of the case, or you can get a custom made external box for house up to a 120.3 from some dude off the net. Can't remember the site but i'll find out if needed. Only prob with that is you'll end up using onger lengths of hose...

SilenX fans look good on paper, but if you look at reviews they really dont perform.

should be fine but your most likely going to have an external Rad, your question about the fans is quite easy, it does depend on the Rad you use to be honest, but whatever rad you get 1000rpm fans just arn't going to move that much air, try source some 1600 scythe S-flex's or some yate's!
