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

[P.X]

I posted before about the 80x80x10 fan I mounted under the M8S pro+ while cutting a 80mm hole in the bottom.

Since I have done one without the hole, because the M8S Pro+ has to slits in the bottom plate anyway, and it makes 1°C difference with the hole.

On idle it runs 41°C and with Kodi playing a FHD stream for 90 minutes it's maxing out at 52°C.

I also lowered the feet to 5mm while gluing the fan on the rubber feet of the box, which is about 2mm.

Take note the I put the fan in suction mode, coz blowing will make noise, and runs significant hotter as well

The fans are 20$ for 10 piece, with free shipping on the bay.


Edit, I also have 40x40x11 heat sink mounted

Nice - Thanks for extra info

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.

Nice idea to double stack.

Might as well stack the two fans and you need some clearance to suck air.

Yes, there is a gap at the back with the deeper feet.

Good idea in chopping them in half. I used a metal band saw.
I now have a CPU fan and under the hood fan. Played 4K for half an hour and temp went up to 60*C only.

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.

Thanks for the info - Sounds good ...

That will be an awesome SoC.

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.

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 ...

[P.X]

Neat.
Nice glow from the power LED

Just noticed ..Toasty warm ambient where you are

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