Vim3 thermal with the new heat sink

Today, at the entrance to work, they also measured my body temperature, I am satisfied with 36.1C° :blush:

Yes it is quite amazing that our human body operates just fine at 36C. :smile:

biomechanics, there’s nothing to be done :wink:

If the VIM3 was mounted vertically and on its side, and the fins were aligned vertically, would that have a similar effect as taller fins?

Mike, do you want your vim to sail away?) :fish::blush:

:grin:
I’m hoping the cables will hold it down in case of a strong breeze.

BTW I’m Mike, this might confuse Robert.:upside_down_face:

I saw in some message, they called you Robert, so I don’t understand either, sorry of course)

100%! :anchor::anchor::anchor:

Yes, actually. You read my mind. :smile:

Of course the default position is horizontal, but, you can always put it vertically.

Yes I am Robert and you are Mike
Please make sure it stays that way :upside_down_face::blush:

I still think bigger is better and a fan to blow the dust out :slight_smile:

Yes, I recall seeing that. Though my name is Mike, evidently I write like a Robert. :grin:
Of course, no sorry is necessary.

I’m working on it…:grin:

Hello. Your new heatsink designs are beautiful!

I can not buy a case in my country and i do not like fans, so i made a heatsink out of a broken geforce graphics card.

Max temp in sbc-bench is 65 Celsius with 23 degrees ambient temperature.

Since bottom of heatsink did not fit, i scraped off thermal pads from old graphics cards and built a spongy interface. It is good enough and very cheap.

Important: do not do this at home unless you are willing to risk destroying your VIM3. Also consider:

  1. Do not let heatsink contact any conductive board components, ever!

  2. After grinding/cutting away metal, brush clean and wash and brush the entire heat sink to prevent any metal dust from falling on the board when mounted.

Final price was 2 Euro.

Cheers!

Nice, but that’s huge.

It will cover the whole pcb so not worried about dust getting inside. :smiley:

For next board, please consider putting cpu on bottom for contact to case. Thx!

Double the thickness of the base plate and you will get much better cooling via lateral heat-transfer.

Good point, thank you. :smile:

I shouldn’t have written ‘much’. It needs to be simulated and the benefits weighted against increased materials costs, of course.

I am curious to see the simulatioin results! :slight_smile: Cheers!

I reseated my heatsink and now do not exceed 65°C . Here are three movies at 640-820p playing at once with -vo x11
With new khadas 5.5.0 kernel and devuan, video playback is fntastic! I do not need VPU acceleration !
