A little loud on full speed but with a good fan curve they are fine. ### ⭐⭐⭐⭐⭐ Cumplen *by on Reviewed in Mexico 18 September 2023* 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. ### ⭐⭐⭐⭐⭐ RAZER KUNAI *by on Reviewed in Germany 7 April 2025* Super no problem ## Frequently Bought Together - Razer Kunai Hydraulic 120MM aRGB PC Fan: Quiet, Powerful aRGB Fans - PWM Fan Controller Support & Connect Up to 8 Fans - Powered by Razer Chroma RGB - 3 Fans - Razer PWM PC Fan Controller: Connects Up to 8 Fans - Custom Fan Curve Profiles - Convenient Fan Monitoring - Thin Profile - Razer Hanbo Chroma RGB All in One Liquid Cooler aRGB Pump Cap: AIO Design - Quiet, Powerful aRGB Fans - PWM Fan Controller Support - Intel LGA 115X Series, 2011, 1200, 1700, AM5 Compatible - 360MM --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/384319369-razer-kunai-hydraulic-120mm-argb-pc-fan-quiet-powerful-argb](https://www.desertcart.co.za/products/384319369-razer-kunai-hydraulic-120mm-argb-pc-fan-quiet-powerful-argb) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-08*
