This is arguably the best *air* CPU cooler you can buy. It is pretty big with the 140mm fans, but in return, you get a much quiet cooler. I easily overclocked my 3.3GHz spec cpu to 4.5GHz using this cooler without trying too hard.. Alright, my i5-2500k might have been a "good un" but the previous aftermarket Corsair only managed 4GHz overclock. People complained about the colour, but come-on guys, this is ridiculous fashion consciousness.Your fellow geeks might be aware of the latest in colour trends, but no-one else care sweet FA about the colour of your cooler fans!
