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

[fandango-fr]

It takes 10 minutes and costs less than 10$ to cool this box (without disassembling it or drill holes, that kind of things), even if summers are very hot where you live. Don't worry.

I have two "L" boxes, one with the Bluetooth Voice and one without. They do run hot, but have not had any heat issues that I am aware of, and I am running the Voice version just as it cam out of the box. For the first week or two, the one with Voice was solid as a rock, but now I get some freezes, occasionally. I have not taken the time to figure out what is causing the freezes but I am running lots of different apps, including the Kodi Beta, which is probably causing the lock ups. At this time, I Would not get worried that you may get a bad box.

Hi,

You will probably be OK. May depend on your climate as well.
Install CPU Temp app and check for your usage and ambient temperature.
If needed a cheap USB fan will help and requires little work. See posts in this thread.
Simply putting the box on it's side will help and is a free upgrade to the air flow.

Well, I am in Central Europe, I don't know if it's cold or warm for this box. I am very nervous now, because after I ordered it I started reading this thread. I don't get how do you achieve 80C temps? Are you runing some ultra blu ray? Or this box was designed bad? I don't get why it's still selling on GB and even a Promo thread here, if I'd be freaktab admin I will never let freaktab promo such garbage (if it is,. I am still waiting for mine)

hi, I ordered m8s pro l yesterday and then read this topic. if I am not going to play 3d games and just watch 720/1080p video, do I need to do something like changing heatsink? I gave 75 bucks and will recieve a not working unit? Or you do this just because you like it?

Can you explain in a tutorial where did you connect the fan wires to in the end as there were many options you tried. I am asking regarding the 5V installation with no switch since I don't have one.

Thanks

Use either USB +5V and any 0V

Close-up Power Points !

Note: Lots of 0V points - e.g. metal port shrouds !!

Topside - Click for Larger



Underside - Click for Larger

Hi, I added a 80mm fan @ 2000 rpm tied in it's delivery cardboard box under my M8S Pro L.
CPU temp shutdown is 20/25 °C playing a 1080 6500kbps video (35 to 37 in idle, 42 to 46 playing 6500 kbps 1080mkv, ambiant temp 21°C. Was 45 to 50 in idle and 65 to 70 playing the video)
The fan is plugged in on of the Mecool USB ports.

Cool 2

To all:

Thanks for the nice thread. I modified my M8S Pro -w just recently.

I have posted it under the M8S Pro -w with voice with photo's and some reported Temperatures.
I used the 30mm x 30mm Pi fan also. Connected to the USB +- direct soldered.

I just received the M8S Pro -L with voice and for a temp solution.
80mm x80mm 12vdc fan with a usb plug...plugged directly into usb port.
Blowing in from the bottom. Temperatures seem to be max of 50-51C no matter what stream
Idle is about 40-43C.

I will modify the - L like I did on the -W after some burn in time of the L.

Cool
Your post in W thread

Further Info - 30mm Fans

I have a Sunon Maglev 30mm fan to try out (£3.50 on The Bay) - Probably not worth the extra money compared to a £1 Pi Fan as the Pi fan is running well below max when at 3.3V so very little bearing wear (probably).

Maglev
30mm Sunon Maglev - Runs VERY fast at 5V and quite noisy.

Resistance 42 Ohm at 5V using R=V/I (I=120mA, V=5.05)

Series Resistor Tests
Direct = 120mA - Noisy
33 Ohm = 75mA - Noise
50 Ohm = 62mA - Slight Noise
62 Ohm = 54mA - Silent
100 Ohm = 38mA - Really Silent (even a 6 inches !)

I think I'll try 62 Ohm - I like silence !

Good thing about the Maglev seems to be that it will still run when considerably under nominal voltage (Series - 100 Ohm=1.25V)
- Std. DC fans refuse to spin-up when below their threshold voltage !!

Hi, if i Don't modify my m8s pro L, 1080p iptv run laggy or smooth ? Thanks.

Smooth. You will face problems only in 4K/60fps
