In my quest for the ultimate quiet PC, I'm thinking of installing a water cooling system inside my PC case and getting rid of all the noisy fans. I've read the article on Tomshardware about the Innovatech cooling kit. There's also other kits available from other companies for different price ranges and arrangements.

As I read more reviews and check out other products, I thought I could use some input from you guys if you have any experience/information on that matter. What do you think I should look into, what do you recommend?

The noisiest fan in my case is the power supply's. It's a 350 Watt PS. My concern is: Can I remove it without risking to damage the PS (Is the fan inside the PS intended to cool components inside the PS itself)? I have a mid-sized tower with a really bigger size than average with still lots of room inside.

My other concern is with the radiator's fan that comes with the cooling kit itself. Really how quiet is it. I do not want to go through a radical change for my system with no meaningfull results in the end.

All input is appreciated.
