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

[clarkss12]

3.3V UART are relatively big pads (square one is -ve, opposite end of 4 is +ve) with holes for small wire.
5V USB are big pins sticking through board on the underside.

HTH

Haha, big pads?? I can't figure out how to get my soldering pencil into that tiny hole...............

[P.X]

How does one solder the fan leads to the board, the connections on the board are soooooooo tiny????

3x 30mm Fan options (Lifted+Lid / 2xSlots / ~28mm Hole)

[P.X]

Yes, better with holes/slots.
Wouldn't say no difference, as throttling involved.

Pro L Stress CPU hits 80°C with throttling to 1000MHz

Pro L with Fan no holes Stress CPU hits 77°C 1500MHz (ambient 17-18°C)

Hot climate and max stress required, would indicate hole/slots needed.

Lift the lid and space fan 2mm away from inside lid ?

Yes, didn't make any difference- went down from 80 to 74C.
With the fan taking fresh air from outside, the temps went down to 54-55C

[P.X]

Strange...in my case it made little difference with the fan inside and lid lifted about 1mm...just 5-6C lower.

EDIT
Sorry - Wrongly annotated - Pro L so should be noted as with 2x Slots cut in grooved lid.

I'll re-test ...

Just meant that putting fan inside leaves the lid with a hole but no fan "bump" !!(though you can fit a fan and have no hole - just space it from the lid a couple of mm and the circulation is enough, at least in England, see pic post 1)


Thanks for the posts

You can get 5V from the USB slots

Yes - USB has 5V across outer pins - Square Pad is -ve (Nearest the power input socket/back)
3.3V from UART is nice if you want slower &/or quieter.

I found 5V 30mm fan listed as a Pi Fan on that Bay for a £.

i was to lazy to cut out a square, so i just done the 30mm round one. (drill it out)
Yips, it is a 12v, was surprised myself it would run on 3.3! couldnt find a 5 volt source inside... now, it is connected on the UART pins.

Yes, that works too

I found you can fit some inside with the std. HS and a small lift of the lid.
Are you sure it is 12V ? Most won't run at 3.3V, but will if rated at 5V.

Fan inside with lifted lid will hardly make any noticeable difference - in my case the temps went down from 80 to 74C degrees. It just needs more fresh air from outside...

Stock heatsink, 30mm hole, with 12v fan running on top (running on 3.3v) 50 degrees when watching netflix HD.
The fan 'sucks' air out of the device, instead of blowing it in.

Yep, that'll sort out any heat issues
