Digital Cable Box clicking/popping noise

My digital box is making a intermittent clicking/popping noise

Could be thermal expansion. Is the box hot to the touch? If so try moving/elevating it to get more airflow. Even so, it's not normal.

I was hoping for an easy fix and I've tried moving it ,even put my small fan near it too without success . Might be time for a call to Telus !
