Thanks for the reply, right before I saw that I was reading about a Typhoon.
The article seems to indicate this unit is lighter though.
EDIT: and according to them easy to install
The Ninja also has two other advantages that make it a better product:
It is far easier to mount than the XP-120, on any of the three major processor sockets currently in use: 478, 775 or K8. We've always maintained that ease of correct installation is an integral, important part of the success of any aftermarket heatsink. The tension on the clips is not low, but it does not require the bite-on-a-bullet-and-sweat pressure of the XP-120's clips to be engaged. It also clears taller components mounted around the CPU socket more easily than the XP-120. These traits mean better user-friendliness and higher usability with a wider range of motherboards.
It is set up for across-the-board airflow, which is the preferred airflow direction for the best case airflow management. A 120mm fan on the Ninja can work perfectly in push-pull conjunction with a 120mm exhaust fan mounted on many mid-tower cases.
Looks good to me, I just need to read and see if it comes with the clips to attach a 120 mm fan or I need to buy a kit.
