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

[clarkss12]

Is there any app to monitor temps while on Youtube or Kodi? Something that works like an overlay?

CPUtemp app

Youtube answer - Power points on Pro L

Underside - Safer +5V USB solder points (please ignore the copper plate!)

Topside - More dangerous +5V power from a resistor ...
and a good position for 0V from the Ethernet port shroud

Hello P.X., I finally got around on doing the RPi fan mod you suggested and managed to solder the cables and the Step Down Module on the bottom of the board like in your pictures. Then fan and the varied speed works but I haven't found a way to open a hole to put the fan in. Is there a problem if it sits on top of the std heatsink? I get 60C with Stress CPU. Is this a good load temp?

Hi,
Well done.
60C sounds pretty good, so I wouldn't bother with a hole.

Hmm so 60 is good? I forgot to mention that that temp is without the top cover Am kinda worried since ambient temp in the summer goes up like 15c and it might not be enough. Also, I think a part of the sound comes from the vibration the fan makes where it comes in contact with the heatsink. Should I just put the lid on top of the fan with some tape on the sides?

Ah !!
Different if no lid !

I would use some double sided foam tape (normally cheap 3m type Chinese copy is good.)

I put small pads on each corner to mount on HS and thicker, small tripple layer pads on top at each corner - do not remove top backing layer so they don't stick to the lid.
Then gently screw on the lid to leave an air gap above the fan and round the edge of the lid.

If you can't screw on the lid try with small pieces of tape at each corner to leave the air gap.
See what temps are like in this set-up ...

Thanks for the experience of PX，I am currently using it first 40*40*15

Neat.
Nice glow from the power LED

Just noticed ..Toasty warm ambient where you are

Hi,

Thanks to the kindness of dbramm22 I have just tried out his find of the ADDA AP3505LB-J70 - A Heatsink and 5V Fan all-in-one.
https://www.jameco.com/z/AP3505LB-J7...M_2235292.html

Lovely neat unit.
I have used a 50 Ohm resistor to slow it down to silent running ...



I have used 4 pads (Stack 4 high x1mm double sided foam tape) to space the lid away from the cooler
(also holds the unit to the SOC as I am using MX4 paste),
and covered the resistor and solder joints



I used the same idea for pads with the SZYTF Turbofan from AlieXpress
https://www.aliexpress.com/item/SZYT...682508049.html



Sadly ...

I have no test data for this lovely combo unit as my M8S ProL has decided to fail on me
Just flashes the Android LOGO a few times and then blank screens !
Probably just a cracked solder joint somewhere but ...


I am pretty sure this ADDA unit will be as good (or slightly better) than the Alloy Turbo Fan unit.
Looks like a quality item and has super low noise with a 50 Ohm resistor.

My best guess is that if you are in the US area then the ADDA is best, but if you can't get a good price on it where you are, then the Aliexpress unit would be the option of choice.

Cheapest option (and safest) is to just use the std. HS and fit a $1.29 30mm Pi Fan (with the four pads for spacing again) as discussed at length earlier ...

Update ...

I was going to try the Oven Bake repair method as a last resort to fix my Pro L, and gave it one last boot-up before consigning to the oven, well It booted fine !!
Must have been a couple of days rest that fixed it.
Could happen again no doubt but for now it is working again ...

(Note: I did try another damaged box with the Bake Repair method once before and it didn't work never booted at all after being cooked for 10 minutes, so definitely a last resort)

Testing Pro L with ADDA AP3505LB-J70

This is with a 100 Ohm resistor
Click for bigger ...


Very quiet with a 100 Ohm, but I ended up using 117 Ohm for very near complete silence.
Using Sekisui Thermal Tape ?? seems OK.

Runs slightly warmer than the SZYTF Turbofan, but that fan is not fully silent, and may not start if more resistance is used to make it quieter !!

Temps (Ambient 20C)
Idle : 50C
YouTube HD : 57C
Kodi 4K60Hz : 64C
Stress CPU : 78C


Overall - a really nice bit of kit that will run very quietly.
Will do the job in all but the highest ambient temp environments with no noise at normal distances.

Thanks again to dbramm22 for sending this HS+Fan - very nice.

Super Cheap Laptop Cooler
£2.18 ($2.80)

80mm Fans (all images - Click for larger)


Simple clip-on back


Cut one set of wires ...


Cut in Half (Cooler + Spare)


Two back legs are taller so swap the taller leg from the spare fan piece.
Gives a slight slope to the front ...


Tape up the wires to give bit of strain relief...
Do a better job than this !


Et voila, a little cooling plinth.

Beelink GT1 Mini has an Amlogic S905X2, which uses a 12nm chip rather than 28nm that S905X uses, this will eliminate the thermal throttling problem. They should be shipping in around a week or so.

Nice job, again, Petre......

That will be an awesome SoC.

Thanks for the info - Sounds good ...
