Hi all,
My XMC-2 has recently migrated to a cupboard with poor ventilation and it appears to be quite getting hot when in standby is this normal? I have the video remains on active, and the main HDMI out is connected to a HDBaseT transmitter as the TV is 25m away. The HDBaseT is showing a constant green light meaning that the video signal is always being sent to the device from the XMC-2 and I imagine that this may be the reason for the heat?
I am putting a fan in the cupboard soon (when the electrician returns to help me) but thought I would ask the question here in the meantime.
NB: If I keep the cupboard door open, even after a good 4 hours of full use, the XMC-2 gets nowhere near this hot.
Cheers!

Keep the door open till you can put a fan in. I'm going to say that this is normal. |

For the extra few seconds it takes to be up and running it will stay cool, and you don’t need the fan. |

The accumulated heat for such a component would be a non-issue. |

The XMC/RMC draw nearly as much power when in VRO (Video Remains On) so the heat build up is almost the same as when fully on. A ventilation fan for the processors is a good idea when in an enclosed cabinet whether you use VRO or not. |

You guys are reminding me that for the very first time since I’ve had full home theater… I now have a CPU fan by default running in one of my components…… The latest Panasonic, ultra high definition player in the system has got one built-in. My stuff is out in the open air, so no need for anything otherwise

The XMC-2 draws around 35 watts when it is ON... and most of that power ends up as heat. And it draws almost the same amount while in Standby if you have it configured for Video Remains On Standby ("high-power standby"). This is similar to the amount of heat generated by a typical cable box or processor. (Obviously anything with amplifiers in it will tend to generate much more heat.) As long as it's sitting someplace where there is any airflow around it at all the case will barely get warm. However, in a totally enclosed space, especially one with wooden sides, which insulate quite well, it may want a little bit of ventilation. (And, if you mount it above something that generates heat, like an amplifier, and it blocks the ventilation for hot air escaping that, it could get quite hot.)

Yeah those things get hot. HDMI is an overhead pig. That means lots of heat. I use AC Infinity fans because heat is no good.  |

Exactly... So, if you only use your processor to watch one or two movies every day for a few hours... And it's going to sit not doing anything for the rest of the day... You can shut it all the way off when you're not using it and not really worry about ventilation... It will probably warm up by a few degrees every hour or so and never get especially warm. And then it will cool down, even more gradually, when you turn it off. But, if you're going to leave it on, then it needs enough ventilation to balance the small amount of heat that it will be produce. Even a tiny amount of actual air flow will be sufficient... but totally sealing it in a relatively well insulated cubbyhole will not. (And wood and MDF are actually both quite good insulators if there are no openings for air to flow through.) This would only be true if the processor is never turned on. When the processor is on it will create heat. Of course yes but you’re starting out cool to begin with. The accumulated heat for such a component would be a non-issue. |

That LITTLE detail regarding 7 channels of ICE amplification within the same enclosure….. did I miss something? The XMC2 heat generation, regardless of the mode is now of little consideration. If you can arrange all of that so that the XMC.. is at the bottom of the pack, you’ll do better as the heat rises. Toss some pictures over here that would be a big help. |

As you've discovered... air has to FLOW... Therefore air isn't going to be able to flow OUT through that vent at the top unless it has a way to get IN somewhere else. And, since hot air tends to rise, and so will want to flow upwards, in order to get air flow through, you would need an opening near the bottom (like the front door). (That vent might be sufficient if you had a matching vent at the bottom to allow cool air in to replace the warm air that exits at the top.) The other thing worth mentioning is that hot air tends to rise and can create air flow... this is called convective cooling. HOWEVER, with convection, since the airflow is driven by the fact that hot air is lighter than cold air, there is not much pressure driving that flow. So, unless you have relatively large openings, with very free air flow, this isn't going to move much air. (Or, more precisely, it isn't going to move much air unless what's inside gets quite hot... chimneys move lots of air... because they get very hot.) Fans are a much more reliable method for cooling... Both because they can move a lot more air... And because they don't rely on allowing the inside of the cabinet to get hot before the air starts flowing... That fan you linked to should do the job very well... But even a tiny little fan would probably do the job... If you were to put that little fan at the top... and then add at least a few small vents near the bottom for fresh air to get in. (Depending on the cabinet, once you add a fan, the gaps around the door might be sufficient to allow air in.) |

Thanks Keith all good points. I think a fan at the top and a vent at the bottom of the door would solve the issue. Its actually the 2 x XTZ's that get the hottest and then that heat has no where to go but up.
Maybe I should also drill some holes in the shelves once the fan and front vent get done.

It’s very neat and well ordered but you’re packed very tightly. It is your amplifier section. Not the processor that’s putting you over. Budget on collecting heat for sure. Is there any chance Where that’s located that you could ditch the back altogether? If not, your electrician will need to come up with a multiple fan, set up to circulate the air all the way around so that it’s exiting the enclosure at all times when operating. |

No chance of removing the rear wall as its ...well...... a rear wall. I might need a fan that can report the inside temperature to an app on my phone, issue is what temperature would be considered too hot? |

As shown in the post above with a photo of a twin fan model, there is a controller that is fully customizable for the temperature at which the fan is activated, as well as fan speed when activated. The temperature sensor can be placed wherever it's needed/wanted. When the temp drops below the threshold you set, the fan turns off. They are high quality, very quiet, very dependable, very affordable, and there is an app for that. acinfinity.com |

What people forget the best way is cool air intake and hot air exhaust is the most effective way to manage the airflow to keep things cool. So if cabinet doors are the deal here at least leave them open for the intake and have the fans exhaust the hot air. If cabinet doors to be closed, then you need an intake fan and exhaust fan system.
