Yes. Mugen means infinity in Japanese (like Honda Mugen). Mugen is Infinity rev.2 . The only difference is included fan (more RPM and made by Scythe - not Akasa, PVM 4-pin too). Akasa fan is a good one by the way. Very quiet, practically inaudible on max speed 1200RPM when placed in closed PC case. It is made for Scythe with certain modifications like additional capacitor. I know because have disassembled one fan and electronically it is different from Akasa original DFS -122512L - I have that one too. The new one will be even better. More airflow means more heat dispersions from the fins, great cooling. It will certainly beat Zalnan 9700 LED. The big advantage for this cooler is that temperatures on full load are only few degrees above that in idle.
There are few minor disadvantage in mounting clips - they are Intel design (poor pressure on the CPU heatspreader) and no other goodies like RPM regulator or nice thermal compound included (Silmore is not good for such a masterpiece in cooling solutions). Infinity/Mugen is near 1kg without fan and won't fit in cases less then 18 cm in width. Also it's fan clips can block some RAM stick with tall heatspreaders when installed lined up with case-fan.
