Good, cheap, quiet socket 478 heatsink, NOT for overclocking.

What is a good socket 478 heatsink that is quiet, and would NOT be used for overclocking. Its for my dad, who just wants to keep his computer stable. Im giving him my old processor, but I dont have the stock HS anymore, so I need a new one. I saw SSS say somewhere that the stock intel heatsink is 39dba, which is REAL loud. Anyone recommend something thats cheap, quiet (30dba max), and would keep it stable?

Oh, also, what would be a good passive NB cooler for the P4C800-E? I lost the retention bracket for the stock cooler, and 875P chipsets have that weird mounting system. So what passive HS is cheap and fairly decent? Thanks guys!

hmm my zalman cooler in my sig (cnps7000 AlCu) was only $30 canadian, and its inaudible (lol almost)

vantec aeroflow would be best... like $18

Arctic Cooling Freezer 4, the freezer64 keeps my friend's cpu at 33c load....but I swapped the stock silent fan with a tornado. At stock its still awesome and dead silent.

EDIT: Most places sell it for ~$30, but directron has them for $22.

How did you replace the stock fan on the artic cooler. Just curious because that fans doesn't really look all that bad.

PEACE
