You have a high end gamer setup with two high end video cards, and 
you write that you are over clocking. All of that means HEAT, in a 
big way.  When winter comes you won't need to turn the heat on in 
your room,  the system should heat up your room quite well, and I am 
not trying to be humorous.. it really will.

In order to control the heat in your PC without it sounding like a 
airport runway, you will have to either swap out your fans to after 
market quiet fans, or go with a liquid cooled solution.  I have 
experience with the former, but not the latter.

I had a similar problem with my dual Xeon 3.06 system three and a 
half years ago. I solved it first by swapping out the CPU fans with 
expensive, but quiet, heat sink/fans. Then I swapped out the case 
fans with fans that were quieter then the seven stock fans that came 
with it.  This involved user some bigger fans, that moved more air, 
but at a slower RPMs =  less whinny noise.

There are lots of different fans available, just do a search on 
Newegg and stick with name brand manufacturers that specialize in 
thermal cooling. There are also lots of website that discuss this 
problem. It is a very common complaint on high end PCs, particularly 
for gamers and over clockers.

The liquid cooled solution has always been intriguing to me but I 
have never tried it. Liquid cooled, done correctly, is one way to run 
even the hottest PC very quiet. There are many different kits 
available for this, again check Newegg, and online discussions for 
recommendations. You might also want to look at Maximum PCs September 
2007 issue page 30. They built their annual <Dream Machine> using 
liquid cooling in which they used parts from two manufacturers, and 
generic parts, to put together what they consider the ultimate in 
liquid cooled quiet, and efficiency.

Just swapping out the two stock CPU fans made a huge difference for 
my Xeon system.... but not enough for me. I ultimately ended up 
building a computer closet/room off my office, and  moving the PCs 
into that vented room and then running all the cables in a 3 inch 
tunnel to my office. Now I have a  power vented computer closet where 
I keep my PCs, and printers and a lot of other PC stuff.

The only heat in my office comes from the three large monitors, and 
there is no PC noise... at all!
Good luck!
