Review: Your buying a name and quality nothing else. - These four new razor fans that I installed were able to bring overall temps down about 7°C and and my GP temperatures from 70°C I’m running intense games to 65°C. I honestly don’t mind the fans noise level at all. I don’t think they’re really that noisy. If you notice my fan on the far left not all the RGB‘s are lit up and that is due to them all being daisychain together and the last one on the left not receiving enough voltage I assume. I I really like that there’s RGB on both sides. Honestly I think that razor products give you Good quality for the most part. But I think any fans can do the same thing that these are doing and if you’re looking at these are just buy the brand name in the Cool light thatcome with them. So if you’re looking for value this isn’t the spot but if you’re looking for your razor fan boy stuff here you go. Warning, if you don’t have an RGB controller or a fan controller you’re going to have to find a way to do that either in your bios or the fans and control them by temperatures or you’re gonna have to get lucky like I didn’t have a GPU that has an RGB controller. Just warning you that there’s three separate wires that need to be plugged into three different places on these freaking fans it’s a mess. Not easy to instal. No value for money. Low noise level. Why 5 stars, because I’m the target consumer for the product. I like razer.
Review: Cumplen - Los ventiladores se sienten de calidad al tacto, el cableado viene con el conector PWD con malla trenzada los cables aRGB no tiene malla pero se sienten de buena calidad. Vienen con con tornillos para fijarlos al gabinete y con sujetadores de presión para los que no quieran usar tornillos. No trae el adaptador para conectar los 3 ventiladores a un conector, por lo que si vas adquirirlos asegúrate de que tú MoBo tenga suficientes conectores o adquirir el cable para unirlos. Con respecto al rendimiento cumplen con su cometido y tiene buena presión, mueven el aire muy bien, no son tan silenciosos como dicen ser pero tampoco el ruido que hacen es muy agudo, si no más bien es un poco grave por lo que al menos para mi no es molesto, ojo, solo zumban a máxima velocidad, lo cual es muy difícil que lleguen. La iluminación es suave y continua, no se tiene parpadeo o pérdida de continuidad al hacer las transiciones en los colores. En mi caso recomiendo que si se tiene enfriamiento líquido, se use en modo push, ya que en el modo pull no alcanza a dar el mismo rendimiento al mover el aire, esto debido que quedan orificios por minimalista del diseño del chasis del ventilado, provocando que tenga fuga de aire o no sea capaz de aspirar tan eficientemente, en las fotos lo tengo en modo pull, la parte frontal del gabinete, pero es mejor en modo push. En general son buenos los ventiladores cumplen su cometido con el enfriamiento y pues por el principal motivo fue por las luces.
