This thing is quite beautiful and classy looking. It also is known to perform very well. There is 1 huge flaw and that is an oversimplified mounting system. The engineering and research that went into the mounting system is 0. They we’re very lazy with it and it’s nearly impossible to mount properly. I would recommend the Be Quiet Shadow Rock over this but be careful because it actually sits up high in an AMD system.

I have a bunch of their fans and coolers. The CPU fans saved me from getting a nervous system disorder when using the crummy stock Intel whining fans. They’re expensive, but you really get what you pay for and they’ll probably last forever. I wouldn’t buy any other brand.
