Muy buen producto por su precio
Muy bueno, antes el procesador me subía hasta los 86°C y ahora solo sube a 70°C en ratos largos de juego

    This thing is a beast. The only system I had to test it on is an ITX board, the cooler is nearly bigger than the motherboard lol. In all seriousness, I have tested this system with a "stock" cooler and it was barely able to keep the cpu below 70c during stress tests. My Thermalright AXP90 had no problems keeping things below 55c during the same tests. This guy is just as capable as the AXP, I realize that my room's ambient temps were colder when I tested the AXP, winter is finally gone and the house is warming up a bit. When I tested this one even under full tilt 3hr stress tests, it remained below 60c and within seconds of stopping returned to 30c which is where it sits when idle. As air coolers go, this is a great value and very well performing unit. It looks quite industrial, but those 120mm fans definitely get the job done. I will purchase this again if I need an air cooler for something that needs more than a basic cpu cooler. Even under stress the fans are not loud, in my open test bench, the fans were no more than whispers.

    You shouldnt be expending more than what thermalright charges in each level

    It works but was very crowded by motherboard. Fans are too big to fit comfortably where needed. I do like the quiet operation but this more a function of the motherboard than the fans. Suggest cables to connect to 2 sources rather than a Y cable to one power outlet. Obviously limited testing for fit. Fortunately the fans can be clipped on slightly offset allowing use with slightly reduced cooling.

    I got this and it seems like it does a pretty good job on lower-end CPUs that don't require a lot of power In fact it wasn't much more for two fans I normally buy the ones with just one fan. I would say it's easy to install but I probably build about 10 to 20 computers a month

    Es muy fácil de instalar, su altura fue la precisa para mi gabinete Segotep Prime G. No quise usar la pasta térmica que trae ya que tenía disponible otra de la marca Artic y fue la solución precisa para mantener fresco bajo carga a mi intel core I5 14400F de una manera silenciosa.
