"in our time with the Noctua NH-L9x65 we can say that it is without a doubt, a no-compromise compact cooling solution. While it may not perform as well as the larger alternatives, it does perform well enough to keep just about any CPU cool, within reason. It does all that while keeping the footprint down to 95mm in diameter and a tiny 65mm tall, thanks to its ultra low-profile fan design."
