So many companies use horrible mounting systems don't know why they think its ok in this day an age. If this cooler was 30 pounds I would by one but not at that price despite its looks.
I installed one of these fans last week for one of my mates and TBH the installation process nearly drove me crazy so I think you should include that point in your overall review ( performance + silence + aesthetics + installation ) with lots of love to OC3Dteam.
xigmatek makes a converter for am2/3 to intel 775,,, its called the "Crossbow Ack Ati775 Mounting Kit" that way you could mount in inverse!!! new egg sells it
