I used this along with 7 Noctua fans to cool off the inside of a cabinet I built to hold my gaming pc (5800x w/240 AIO + 3090fe neither break 65c under gaming load) work laptop, small network switch and my APC. The install and configuration process is incredibly simple and works right out of the box. I mounted this externally from my PC case but it has magnets that allow it to stick to the metal of your case. The fans are mounted using AC Infinity grills. I created a couple custom fan curves, one Idle and the other for Gaming. I’m not going to take any stars away but there could be some improvements to the configuration. I’d really like to see the option to set the fans to 0 RPM. Might not be the best option for me but I can see where it would be beneficial. I’d also like to see a PWM option, that allows you to control the fans speed based on the GPU temp, currently on the CPU temp is taken into consideration. I emailed Razer’s suggestion box so it could still happen. If you’re working on a “hidden PC” or PC in a desk, this has to be on your component short list!

I really like having just one program for everything so this works perfect for me. Just needs an update to let the fans be controlled with the GPU temp and this will be the best fan hub for someone that already has razer stuff.

El producto funciona perfectamente, para ser de Razer deja mucho que desear en cuanto a calidades, tanto el plástico del producto como los cables se ven muy mal. Del resto genial.
