The last thing you expect is to receive a product that simply does not work. It happened with the fan of the cooler master hyper 212. It simply would not work, probably a broken wire internally. Have tried to connect it to different power outputs in my mother board, but finally realized it was burned. Now I need a new fan, probably from a computer shop nearby.<br /><br />I wonder what kind of quality control they have at Cooler Master. I had them as 5 stars supplier for cooling stuff, but now i have to give it then no stars at all!<br /><br />Another thing that needs improvement is the installation instructions. It's very confusing, too much details and small fonts and illustrations. If you are not an experienced computer guru you will spend about an hour to figure out how to assemble it.

Tengo 2 meses ya con este equipo y sinceramente el rendimiento es excelente. Solo hay que agregarle memoria adicional y listo, se tiene un producto espectacular. A la mia le agregue 4gb mas de RAM DDR3 y ahora puedo correr WIn 7 y 2 maquinas virtuales de Linux a la vez sin experimentar problemas de rendimiento. Los juegos corren como nunca y las aplicaciones vuelan! Ademas el puerto USB 3 vale por si solo. Compre un disco portatil con USB 3.0 y puedo transferir 700mb en tan solo 5 segundos. Las cornetas tienen un volumen altisimo y con buena definicion. Una recomendacion TOTAL. Cons: Sonic Master en ocasiones distorsiona el sonido
