Hi

The cable has release clips for you to unplug it. Click here to see the cable specs. 

The front fan is not that loud.

Thanks - I pressed in the release clips, the one facing to the top of the amp doesn't like to let go.

If there a part number for the cable?  I tried the one in the cable but Dell's parts site didn't pull it up.

Ok, now I have it running, and I have a couple of other questions about the thing.

Is there any kind of performance difference between using the HDMI on the laptop vs the graphics card?  Right now I just have a 1080p monitor, so I don't need 4k/60 support (my A15 R1 doesn't have an HDMI 2.0 port), and my monitor only has a single input, so it's a little more convenient to just leave use HDMI on the laptop when I'm not using the AMP or when I am using it.  I wasn't sure if that ate up some of the PCIe bandwidth or how the video stream was returned to the laptop in that configuration that could result in lower performance - although at this resolution with vsync on I'm pretty much going to be capped at 60 anyway.

The cable part# is NPY83, also, you can use any HDMI port, it will not make a difference.
