Silencing my P4

[Spider]

Currently have a P4 3.0Ghz in my Media center PC using the stock intel HS/F (I know!).
The noise is driving me nuts in the living room, so I'm looking for a silent alternative.

Don’t really know what to go for – should I go for a fanless cooler (will this prevent all overheating) or just a really quiet HS/F? Can anyone recommend something for me please?

Thanks guys.
Its used exclusively for MCE2005, so will never be overclocked or anything like that. All I want is the quietest solution for the job....
