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

[helyblackstorm]

Yes, I'm Brazilian, lol. I also bought in "Mercado Livre", but I opted for the RPi 3 model with only 7mm in height. This one is 10 mm from what I saw in the image and description. The freight of the ML is very heavy, even if it is registered letter.

But coming back to the temperature, I honestly think you are blessed to live in a colder place. This counts a lot on the temperature of the device, one day it rained here and it was very cold, that day my TV box was in the range of 38 °c.

It seems to me that you have not used any resistors, do you understand a bit of electronics? Could you send me a picture of the soldering points you made? Another question, was that annoying noise, for example at night when no external sounds?

......

Sim, eu sou brasileiro, haha. Eu também comprei no Mercado Livre, mas optei pelo o modelo RPi 3 com apenas 7mm de altura. Esse seu é 10 mm pelo que vi na imagem e descrição. O frete do ML é muito pesado, mesmo sendo carta registrada.

Mas voltando a temperatura, sinceramente acho que você é abençoado por viver em um local mais frio. Isso conta muito na temperatura do aparelho, um dia desses choveu aqui e estava muito frio, nesse dia meu TV box ficou na faixa dos 38°c.

Me parece que você não usou nenhum resistor, você entende um pouco de eletrônica? Poderia mandar uma foto dos pontos de solda que você fez? Outra pergunta, ficou com aquele barulho irritante, por exemplo a noite quando não sons externos?

Note: MercadoLivre or MercadoLibre is a Latin e-commerce similar to Aliexpress, but prices, especially shipment, are not even similar. loll

Yes ... it ends up compensating to pick up in the aliexpress..the problem is the delay to arrive ... but I did not even call in that pitch of the height ... with 7 mm the fan is not exposed ... but it is not found here ... and if you think it's 50 reais off the freight.

Yes ... I observed this: in these colder days the temps decreased by 5 ° C ... but most important is that the temps do not exceed 50 ° C ... I think it is a good limit .... because in stock reaches almost 80 ° C easy .... from 50 ° down the life expectancy should increase greatly.

I'm from Minas Gerais ... it's a temperate climate ... neither too cold nor too hot.

I understand nothing electronic ... so you have an idea I asked a friend to weld for me ... kkkkkk .... the detail is that soldering in the USBs both in front of or behind the board the fan worked ... only when I I pressed the power on the remote control the device turned off ... but the blue light was still on and then I could not turn on the device .... then I tested the pads on the SD card (3.3ve GND) behind the board and it worked.

As it is 3.3v the positive I think it did not even need a resistor ... and on the noise did not notice ... unless it touches the ear very close to the device.





Sim...acaba compensando pegar no aliexpress..o problema é a demora para chegar...(tem coisa que comprei da China em outubro do ano passado e não chegou até hoje, ou roubaram na receita ou nos correios...nem coloquei isso no texto para o pessoal não ter mais uma péssima impressão dessa vergonha que nosso país é)...mas eu nem me liguei nesse lance da altura...com 7 mm o fan não fica exposto...mas não se acha por aqui...e se achar tá 50 reais fora o frete.

Sim...observei isso: nesses dias mais frios as temps diminuiram uns 5° C...mas o mais importante é que as temps não ultrapassem 50° C...acho que é um bom limite....porque em stock alcança quase 80° C fácil....de 50° para baixo a vida útil deve aumentar bastante.

Sou de Minas Gerais...é um clima temperado...nem muito frio e nem muito quente.

Entendo nada eletrônica...para você ter uma idéia pedi para um amigo soldar para mim...kkkkkk....o detalhe é que soldando nas USBs tanto na frente ou atrás da board a fan funcionava...só que quando eu apertava o power no controle remoto o aparelho desligava...mas a luz azul continuava acesa e depois não conseguia ligar o aparelho....então testei nos pads do cartão SD(3.3v e GND) atrás da placa e deu certo.

Como é 3.3v o positivo do pad doi cartão SD acho que nem precisou de resistor...e sobre o ruído não notei...a não ser que encoste o ouvido bem perto do aparelho.

Ok I installed the fan and closed it up to test. Amazing! Thanks for everyone’s help and patience. I don’t know if now I will install the resistor’s as I can’t even hear the box with a show playing. Prior to having the fan installed temp was 150-183 Fahrenheit depending what I was watching. Now a full hd movie 113 Fahrenheit or lower. This is great, again this is a big drop in temp just adding a fan. Had to extend the wires to mount on the bottom of the board than used wire shrink tube looks good!

thanks again!

Now I saw, thanks man! Aliexpress has many vebdvended and just was finding different models of his.

[Novato]

I already found it, it was easy, lol ... But thank you always

[Novato]

mirbg , link of heatsink please?!

[Novato]

But be careful with the thermal pad you are going to use - don't let the heatsink touch any of the elements around, otherwise you will cause short circuit and will permanently damage the box.

That struck me as quite scary. You could send me the link of the items you bought, I will need to import from other oapaís because in mine does not sell this heatsink. Could you also send a photo of the welding points you made?

[mirbg]

Hey mirbg, to me this is cold yes. lol ... Here the temperature is warm, I'm right in the middle of the equator. And in that period it is even hotter.

I'll try to replicate what you did, although it makes me very sad to think about cutting the bottom of my box. But I have to create courage and perform (maker).

Don't take it so dramatic, you won't see it anyway as long as it's on the bottom side.
This helps really a lot to reduce the temps.
I highly advise you to do it, but be careful with the thermal pad you are going to use - don't let the heatsink touch any of the elements around, otherwise you will cause short circuit and will permanently damage the box.

[Novato]

So, after replacing the default heatsink with 38x38x6mm



I got this result:

Idle - 27C
HD/FullHD - 30-32C
4K - 33-34C
4K/60fps - 35-36C

I really need the link from this dissipator, I loved it, lol. He seems to have a much greater dissipation power. Could you send me the heatsink and thermal paste link that you used in your setup?

[Novato]

No, the location where I live isn't cold. 21-22C in house. I used 1mm Arctic Thermal pad, 40x40mm 12V Evercool fan, working at 5V.

Hehehehehe

I do not care much about the appearance ... it is downstairs in the bookshelf ... almost you can not see ... anyway I'm kind of bad to mess with these things and I do not have the right equipment .... but the temperatures that were middle high were my main concern ... it got much better after I put the cooler.

In fact I just put the cooler and soldered the wires behind the board on the pads of the SD card (3.3v and GND) .. I did not put thermal grease ... nor did I punch holes or changed the heatsink.

But for your nickname and with the post that you said that here costs three times more I believe that you are Brazilian like me. I bought this seller's cooler:

https://produto.mercadolivre.com.br/...-raspberry-_JM

I bought 2 for the freight that was almost double the price of the cooler.

I asked him to send the screws for fixing and screwed the fan to the CPU heatsink ... I believe that what made the difference ... I just do not advise to force too much because the fan is fragile and can break easily.

Now with this cold front the temps lowered more:

Idle: 28 ° C
Youtube 4K: 34 ° C
Stress with Kodi, Antutu and Geekbench: 44 ° C MAX

, I got this result:

Idle - 27C
HD/FullHD - 30-32C
4K - 33-34C
4K/60fps - 35-36C
StressCPU:



And my very final setup:












Before cutting a hole at the bottom and changing the default heatsink, it was 53C under full load with StressCPU. Now it's almost 10C less under same load. I don't think I could achieve any better result, this is the limit with this combo - slim profile and closed box.

Next step would be water cooling (joke, of course) 😉

did u use the existing screws to hold the lid on after the fan install or a longer size? I will try connecting and c how it sounds. I found this picture online from an install or I took a screen shot from a video. Can u confirm these r the ones I need to solder the fan too?



thanks

Those are the 2 spots to get the 5 volts.

[LilSnoop40]

Looking good.
That way up the fan can't hit the sink, but could touch the lid depending on hole size. You can try without the resistor(s) to check and feel the noise !!

Hello! I envy your temperature chart, it's all very cool and attractive to me, minus the way you left the fan out is clear. lol ... Unlike the post with previous photos from mirbg, I noticed that you only use a common fan for Raspbarry Pi3 30mm, have not seen holes in the bottom or mentions about having changed the heatsink, thermal paste or have put additional heatsinks in the down of the board of box. So I wonder how you got such good results? I keep asking these questions in my head: Have you used resistors to reduce the speed of the fan, if so how many ohms? Did you use thermal paste, if so of which brand? Does the location of your home where your box is located have central air or air conditioning to keep the temperature cool? I do not know to but here the coldest day in the morning my Box did 38° c, and usually stands in the range of 44-46° c, already in games the temperature will stay in the range of 50-55° c, I really think this still much is hot, then I wanted to optimize the normal temperature to 35° c and in games to at least 45° c, so I would be happy, of course, without installing a bigger fan or using less creative techniques ( but effective at times). Note: My room has no refrigeration whatsoever, and it's hot until the evening.

Hehehehehe

Hehehehehe

Nem preocupo muito com a aparência...ele fica embaixo na estante...quase nem dá para ver...de toda formna sou meio ruim para mexer com essas coisas e nem tenho equipamentos adequados....mas as temperaturas que estavam meio altas eram minha principal preocupação...melhorou muito depois que coloquei o cooler.

Na verdade eu só coloquei o cooler e soldei os fios atrás da placa nos pads do cartão SD(3.3v e GND)..não coloquei pasta térmica...nem fiz furos ou troquei o dissipador.

Mas pelo seu nick e com o post que você disse que aqui custa três vezes mais acredito ue você seja brasileiro como eu. Eu comprei o cooler desse vendedor:

https://produto.mercadolivre.com.br/...-raspberry-_JM

Comprei 2 para valer o frete que estava quase o dobro do preço do cooler.

Pedi para ele mandar os parafusos para fixação e parafusei a fan no dissipador da CPU...acredito que isso que fez a diferença...só não aconselho forçar muito pois a fan é frágil e pode quebrar facilmente.

Agora com essa frente fria as temps abaixaram mais:

Idle: 28° C
Youtube 4K: 34° C
Stress with Kodi, Antutu e Geekbench: 44 °C MAX
