Edge-V: New VIM's Heatsink


#1

Hi Guys!

The new heatsink for the Edge-V is here. Gouwa wants to know which type of heatsink you prefer:

1. No Cut in the Middle

2. With Cut in the Middle

Option (2) might allow users to mount accessories on top of the heatsink in the future…whereas Option (1) may look more aesthetically pleasing. Note: These are CNC-machined samples, so you can see some defects in the high resolution images.

option 2

what accessories can we mount


#3

I’m for the second option to be able to mount different fans. :slight_smile:


#4

Emm, not quite sure, maybe, Popcorn when you watching the movie with LibreELEC

For HTPC use and most industrial applications a passive heatsink is better (quieter and nothing to go wrong electrically or mechnically) so IMHO it would be better to ship a heatsink with larger fins that cover the width of the board (not 50%).


#6

Agree, we just designed with a high speed and super quite cooling fan to balance both good heat spreading and performance. :sunny:


#7

As a “function over form” guy, I prefer option 2. Though personally, I think option 2 looks fine.:grin:


#8

More holes yes
To mount more Alloy, option 2 is a good start,
Like It

hmmm i like the 2º one!

It will be very good if you make the USB ports double (now they are single). This will increase the overall height of the Board and can increase the height of the radiator fins.
And turn the 40-pin connector over to the bottom side of the Board.

Personally, I’m thinking that if the 40-pin GPIO is put on the underside of the board, then that creates space for a wider (not necessarily taller) passively cooled heatsink on the top.

After my investigations in this thread, I’m quite convinced that the VIM2, at least can be passively cooled rather effectively (even with the VIM Heatsink), at an ambient temperature of about 23C.

Of course, placing anything above the heatsink obstructing the convective air flow, will render passive cooling infeasible…

Some Thoughts:

  • A large aluminium heatsink may be more expensive to manufacture.
  • Some people may consider it ugly.
  • From my design background, I know its possible to make these things look cool.

It is possible to combine functions of the top (metal) cover of the case and a radiator. You can use the entire top cover as a large passive cooling radiator.
