Noctua NH-U9 Low Noise Heatsink
 

The NH-U9 comes with all the necessary mounting hardware you'll need for Intel or AMD processors, but no fans are included. Mounting clips will allow users to install a 92mm or 80mm fan on either side of the unit if they desire, but we found a single fan more than sufficient for the task at hand. The 38 nickel-plated aluminum cooling fins are connected by four copper heat pipes to a copper base plate that pushes the overall weight to 570grams.
