Read the statement by Michael Teeuw here.
Monitor Overheated
-
I took the monitor itself out of its casing and had it flush with the frame itself. On the back side I had 2 small supporting braces sandwiching it in place. The back itself was mostly open with 2 strips of plywood covering about 2/3’s of the back.
-
My only guess here is that there wasn’t enough ventilation along the back side. Those backlit LEDs do get hot, and having it flush up against something, specially something that doesn’t conduct heat well, will cause them to overheat. Always leave some breathing space behind the panel, and as others suggested, a quiet fan to help move air doesn’t hurt.

@RHeniz hi! did you find any reliable “advanced” solution regarding this heat issue? like turn on the fan(s) as soon as the temp in the box reaches a certain level? i am a bit surprised that nobody talks about this topic… i am still building my mirror so didn’t faced the problem yet but i would have think that a source of heat (monitor/rasp) in a closed box would somehow produce heat and therefore evacuation of the heat would be needed (more then some holes…) If anybody would like to share their opinion, please feel freev:)

@bibi I haven’t replaced mine yet but I might try to find a way to turn the monitor off and on with a time or remote so it’s not always on.

@RHeniz ok let me know what you would find. i share my idea which is to use the usb port on my monitor to plug in 1 or 2 modified PC fans… i guess with a PIR sensor installed as well, the rasp will switch on/off the monitor when needed and therefore power monitor usb ports accordingly (i am not sure that’s gona work :)) Other opinion i have thought about is to plug into the gpio’s the fan and control the temp via a sensor, write the code to activate the fans accordingly to the temp value setup in the code… much more “complicated” way for a newbie as me but interesting one! (would be nice to get help on this from someone ;-))

You can follow the following steps to prevent monitor overheating.
- Clean the inside of the computer to get rid of dust particles which may heat up the monitor.
- Avoid hot devices near your computer .
- In case of overheating, shut down your computer and let it cool down.
-
Make sure you have top vent holes… heat rises… let it!
The other thing you could do is to use modules like MMM-ModuleScheduler to turn off modules and/or mirror when you don’t need it on like all day when you’re at work/school…
That’s what I do and have had no issues… :)
