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

The easiest way to test if it is hardware of firmware problem, do a factory reset and start over......... You may experience an occasional freeze, but never a reboot....

Thanks. I'll give that a go and keep my fingers crossed for a software issue and not a hardware failure.

Most of the old timers on here can tell you the horror stories about these sicks/boxes from 4, 5,6 years ago. If you could go a day without several reboots or a dozen freezes, you had a good device. Thankfully, those days are gone, and these boxes are very stable now. Usually, the freezing issues are due to bad drivers that some apps install.

One other way to VERIFY that it is a hardware problem, install LibreELEC or CoreELEC and that will tell you for sure....... Those OS's NEVER freeze or reboot.

Thanks for the advice. I performed a factory reset last night and installed a few of my apps and I'm quietly optimistic that you nailed it as a software issue. After an hour or so of streaming and stress testing using stressCPU and the device reaching temps of 80c I suffered no reboots or crashes. I'm at work now but will do some more tests tonight before installing missing apps and testing each one to see whether one of them was causing the issue. Perhaps there's something odd with my setup the OTA update didn't like even though I cleared cache before I ran the update. Just wanted to say a big thank you for steering me in the right direction to diagnose the problem. Keeping my fingers crossed issue is solved as its the most stable the device has been since purchasing. Also a lesson learnt for the future to always do a factory reset when stability issues arise.

My Frankenstein's temperatures are getting better, probably because the Sekisui tape has bonded better.

20c idle, which is maybe 1c higher than ambient, and 42c streaming 1080p Acecast for a few hours, which is pretty demanding since it grabs chunks from hundreds of peers, assembles them, and serves them to VLC on the fly.

So my recommendation would be to forget resistors, buck/boost converters, thermal switches and fans, and soldering shit where you shouldn't. Ditch the ugly ass enclosure too.

Instead, grab a couple of small heatsinks for RAM and EMMC, and a hefty one with a 35-40mm base, and secure them with some Sekisui tape, or whatever, I don't think it matters that much.

Wow, how amazing, will it just put the heatsinks in the ram and rom memory will give better cooling? Could you take a picture of your box so I can see how it got?

[Novato]

Hi, jebivetar, sorry for my inattention, I've seen your box before, now I understand the Frankenstein's, lol. I really think the cooling of your box should be due to this huge heatsink in the shape of cockatoo head. But anyway, it's still a very encouraging result.

Sekisui Tape is interesting - seems thin which is a good start.

See Post 2 ... 38 - 40mm heatsinks for a dollar or 2 are noted as the best passive options.

I am sure your magnificent blue HS is a leftover from an earlier project - cost about 18-20 USD when new ! now sold out.

Just taking off the lid would probably solve most peoples issues, but not everyone likes the open box look. It is the cheapest simple solution.

Removing the heatsink is probably more dangerous than soldering to the large USB pins on the underside (ask Ronnie about heatsink/box death )

Everyone to their own - must say I do love your Big Blue HS (Stegosaurous ? Mohawk ?? Franken-sink ??), but I also love my slimline 30mm fan and flat grill

This looks exactly my taste! Good job!

Forgot to say ...
The fan grill is cut from the fan orifice in the pressed steel backplate on an old set-top box.
Sprayed black and superglued in place.

This desing is beautiful! ... But it is still not enough for me to perform on my ... Try to pre-fill the hole in the lid with perforated screen for acoustic box or screen of metal, you glue the inside of the lid before you put on the tape or you can make a floor that fits into the hole. Be creative, convince me!

This is not a contest, you know. No need for nobody to convince anybody. We are just sharing an ideas here.

You also know that this was not the intent of the text, correct? I thought, maybe I should spell it out in the text, but I thought later, he will understand what I said. Yes, it's just a suggestion, if he wants to challenge himself to do something new he might try this. I think he's been challenged all this time, whoever sees his videos knows that.

But I apologize if it was offensive, my intention was just to express my idea and make a little grace in the text.

No worries

I have a big sheet of "HEXX" grill but it is too lovely to cut !
