Razer Kunai Hydraulic 140MM aRGB PC Fan: Quiet, Powerful aRGB Fans - PWM Fan Controller Support & Connect Up to 8 Fans - Powered by Razer Chroma RGB - 3 Fans

The RGB is absolutely beautiful and I love how vibrant the colors are. Then again, I do particularly like Razer products and wanted to give their pc components a chance. When the pc is idling, it’s very quiet. The build quality is solid and the fans are sturdy. As for installation, it wasn’t easy but it wasn’t hard either. The daisy chaining was the hardest part. For those looking to get better performance for their money, these are not the fans to buy. Not saying they don’t work well, but they are very expensive. Other than that I have no complaints.

Super bright and clean glow. Looks perfect in my razer case.

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.

I really like these fans. I just helped my son build his first computer which he worked with me and saved up for an i9 12900K, 3070ti. He was leaning towards the Lian Lu fans but I let him test these review units in his computer. We both agreed that the build quality of these is very good. They feel precision made, smooth operating and quiet. Even at full speed the blades don't seem to make as much of a whine or whirling sound. They also move a lot of air. We tested them exhausting air which is the front side in orientation. We also reversed them with the backsides facing in to use them as intakes. You can see the wires exiting and the backside of the fan, but the LED's still look the same on either side. He decided to spend his money on another set so that he now has all Razer fans. We both agree that these get 5 stars. They are premium fans. The price is premium, but they do seem to reflect that in the quality and performance.

Very happy to see they made it to their destination without issues! 10/10 (or 5/5) great job either way!

P nice fans, not the loudest. love the lights. little flimsy.

The fans work well with other Razer products and their synapse software. I’m controlling these with the Razer PWM fan controller and the Razer RGB controller. They get rather loud once over 1200 RPM and are a little expensive as well.

These were just what my son was looking for. Glad we can get Razer brand on Amazon.

Perfect product i wish the seller or amazon sells the pmw controller

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.

Super no problem

Requiere un adaptador de conector de 3 pines para el ventilador si su sistema solo tiene 3 ya que viene con 4
