Every single one of y'all completely missing the point. This cooler is meant for a tiny mITX case such as Antec's ISK 110 VESA, which it fits in perfectly and the stock Intel cooler doesn't. The fan that comes with it is entirely insufficient, I had to upgrade it to one with much higher CFM to achieve the performance I wanted which does easily exceed the stock cooler. The new fan is audible, but not noticeable when I have my TV on. I have a ISK 110 case mounted to the back of my monitor on the desk in my bedroom. The case only affords 65mm HSF vertical space available.
Now if you want quiet and to blow away Intel's stock cooler and fit in a tight space, i.e. ISK 110, the Prolimatech PRO-SAM17 Samuel 17 with Prolimatech PRO-USV14 140mm Ultra Sleek Vortex Fan barely fits the 65mm threshold in the ISK 110.
