Gotcha! I have a couple of options and to do's 1, remove fabricated foam between towers to allow better airflow. Bonehead idea! But looked good at the time... 2, Move RR to right side and 3, possibly add a 12v DC motor thermostat controlled fan. Either directly on the RR itself or very close to it. I have a new SH847, so heat shouldn't be an issue! However, nothing wrong with keeping things cool...Dont forget your RR needs airflow to avoid overheating.
