Query: Ultra Quiet and Ultra Cool

this cooler is simply amazing...i upgraded my cpu from a p4 2.0ghz(northwood) to a p4 3.0ghz(prescott) and i was heating up to 60+ degrees during full load with the stock intel cooler...with the help of arctic silver 5 thermal grease with this zalman cooler temps are capped to 49 degrees while overclocked to 3.4ghz under full load...installation is a little difficult at first and may require some thinking...i can see how people can install this improperly and not get the results that i did...price - goodnoise - quietstyle - awesomeperformance - greatinstallation - trickythis is by far one of the best coolers out there...just make sure your case has the room because it is GINORMOUS!!!...and did i mention it looks way cool...pun intended...
