Possible to upgrade a 2007MBP fan?

I haven't really seen what the new fans look like but mine are noisy as heck when they start speeding up... so I was wondering if it'd be possible to get one of those new silent fans in a mid 2007 MBP even if it required messing with the new fan a bit to get it to fit/screw in properly...

Edit for Clarity:

I have a MBP 2007 model and I want to use one of those quieter fans from the 2012/2011 Models and would like to know if there's some DIY way to get them to work in an older MBP

 

Sorry thanks, I made an edit to clarify my question. It's very late and I'm pretty tired... sorry for not being clear.
