Question: I have purchased this model extender before and unlike the ST-C6HD-DA-HDBT, this model has a noisy internal fan operating all the time. Do you have an extender that supports 4K but that does not have the internal fan?
Answer: Thank you for your inquiry,

We are sorry to hear the noise is above comfort level-

For a fan-less 4K (@30Hz) HDMI KVM Extender, we would recommend looking into the Rose CRK-1DTXT-HD6 HDMI KVM Extender.

For a fan-less 1080P / FHD HDMI KVM Extender, we would recommend looking into the Adder XDIP - you can connect two of those nodes directly using a single cable up to 330 feet (100 meters) in length (or via a network switch to allow interaction between receiver/transmitter combinations).
