This hot-sway cage is excellent! I'm using these for an Unraid server that doubles as a gaming rig so it's in the same room as I am. The fan is a bit for my tastes, and it is a non-standard fan that doesn't use the connectors for computer fans ( if i'm not mistaken is uses the same connectors as servos.) I had to get creative by completed removing the fan from the housing, and screwing a pwm fan onto the back of the fan grill. This allows me to use a larger standard fan and is much quieter. The temperature did go up by a few degrees, however they are still well within safe operation ranges.
