Overheating Mecool M8s Pro L and Pro + (and others ?) - Options ???

[Albertron]

I am playing movies, both x264 and x265 hevc through the android Kodi version and every now and then the box stops working. The image just freezes like that I the only thing I can do is unplug the power cable to get it working again. Is this normal? Or do I have a faulty box and need a replacement?

I have also had a freeze, when I was watching through kodi an HD channel of my vu + solo2. The TV box was at 80 degrees Celsius. So I guess it's the fault of overheating.

Bigger fans are normally 12V and not all spin at 5V (USB pins) and fewer at 3.3V (UART pins)

My Pi 5V fan runs slowly and silently and draws air in through a large hole but will still work even with no hole as circulation is enough in a cool climate and not pushing 4K at 60Hz.

Bigger fans can be noisy and have to be mounted outside (probably).

I've posted before about the method if you don't want a hole (little pads of double thickness 15mm x 1mm 3M sticky rubber double sided tape to space away from lid)

First post has data from various fan fitting methods.

OK, Thank you very much for the help. And Sorry for my english.

Fan connected to UART pads.
Square Pad is -ve

Pro L with a 40x40x11 HS Mounted Diamond Style


OK

Thank you very much! It is better to put the fan extracting air or blowing?

With a 30mm fan would it be enough? Will it refrigerate more one of 40 or 50mm?

Are you worried about noise ? The waste of energy ? Wear and tear on the fan bearings ??

Noise is not a worry if you use a 5V fan at 3.3V, at least the one I got.
Energy is vanishingly small, much less than most standby current.
Wear and tear would be my only concern.

You could use a radio remote power socket switch.
Often come in packs of 3 or 4 but a pack of 2 can be found for about £10 I think.

If you can find a power line on the board which is switched then someone could probably design a simple FET/transistor switch to put in line with the fan !!!

Otherwise some passive options are detailed early on ....

remote power socket Switch is good idea. Thanks
One more question. Where do I have to solder the fan cables exactly?
Can someone upload a photo to see where it is exactly?
I have the pro L

[P.X]

Mine does..., but I don't have the "L" version, just a regular PRO.

Ah, different me thinks !

Yes, as long as you solder it on the underside of the PCB, at 5V on the one of the USB's.

Does your 5V USB turn off when box is in OFF Mode ? Mine doesn't ???
(EDIT : Pro L)

Is it possible to add a fan and that it is deactivated when we turn off the tv box? I need this, because I use the TV box to sleep and I do not want the fan to be on all night.

Thinking ... With the UART pads, you could try poking the wires through the holes and soldering on the underside of the board !

[P.X]

Pre tin the little wire end
Poke end into (or at least against) the hole
Press soldering iron (pre tinned again) against wire and pad
Wire should slide into hole and tin the pad at the same time

at least that is the theory !
