"The NH-L9x65 just opens up even more options for AMD CPUs that have higher TDPs than the L9a can handle as well as the 6700K that caused the need for the L9x65 in our upcoming build. The move back to a universal mount does help with those options and it means if you want to switch to or from AMD or Intel you have the option. Like all Noctua coolers the NH-L9x65 is quiet and its cooling performance was spot on as well."
