Looking to make my system FANLESS

Hey guys, recently I have noticed that my computer has been very loud, dusty, etc. I cannot keep up with it all, it is making my room very hot (~80ºF), and I need make it silent and cool!.

I have decided I think I am going to invest in heatsinks. As I have not been around the hardware scene in a few months, I was wondering if you guys could help me out.

AMD FX-55
ASUS A8N-SLI Deluxe (nForce4 SLi)
Dual 6800 Ultras

I have thought about:
Thermalright XP-120 CPU Cooler
Thermalright HR-05-SLI Chipset Cooler
Thermalright HR-03 VGA Cooler

I am also considering an upgrade once AMDs new Barcelona comes out, so will these be my best decision as far as coolness goes, and will they be compatible with what I upgrade to? Also, if I were to get a fan for any of these, would the Panisonic Panflo be the best?

Thanks guys!

"To give you an idea of how massive this heat sink really is, the XP-120 utilizes a 120mm fan!"

That quote is from a review one of the models that you mentioned. It says that it uses a fan. The subject of your post is asking about a fanless system. There is also a fan in the power supply. How is that eliminated?
By no means, am I a hardware guru, so could you explain those two things to me.

You do not NEED a fan for the XP-120, there must be a way to use it without a fan, or a heatsink (made by Thermalright) that doesn't utilize one.

As for the fan in my PSU, PC P&C = almost silent =]

IGNORE THAT.

Now considering WC.

Recommendations?

yeah go for water cooling
would make it "almost" fan less
