Ok ill try to answer all q's
Fans are not loud, but not dead silent either. I see people claim other lights fans are dead silent. That isn't the case with these, and to say they are would be misleading.
At 45% on each channel the fans dont come on. They come o. Around 55%.
Same setup and programming for all x150,x200&x300.
Theres not much for instructions, unless they started adding them, but when you program each channel (color line) you will see which lights it changes.
Yes they to ramp up and down in between each time set. So lets say 1400 -10%
1800 - 55%
Then at 1500 it will have ramped up to lets say 42%.
As for programming, when you plug the master in, it turns on. On the device that has the app, you go to the wifi, the mirage x wifi will show up. You connect to it, then open the app. Here is a pic of the layout per channel. The x300 has another square of led clusters.
When you open the app, you click on the icon in the pic, then choose one of the 3diy icons. Then the page with the 4 channels appears. You click on each channel and program the times and % at each time. As a heads up it only works with military (international time)
