Banana Pi BPI-R3 mini new shell

Banana Pi Router design BPI-R3/R3 Mini(MT7986)

Due to the poor heat dissipation of the original shell, we have redesigned a brand new shell.

The old shell relies on a top mounted fan and a metal casing for heat dissipation; The new casing has added heat sinks at the bottom, and the top mounted fan has become the bottom.

Next, compare the differences between the two casings under IDLE and pressurized conditions.

R3 mini idle temperature for one hour

  • Old shell:

    1.CPU: 56 ℃

    2.Top cover, right cover, Ethernet side cover, USB side cover, left cover, bottom cover:

    43.1℃ , 48.5℃, 45.9℃ ,51.2℃, 48.0℃, 50.2℃

Use “stress - vm 10- vm bytes 180M - c 4- io 10” for pressure testing

  • Old shell:

    1.CPU: 66.5 ℃

    2.Top cover, right cover, Ethernet side cover, USB side cover, left cover, bottom cover:

    47.5℃ , 53.5℃ , 53.8℃ , 54.9℃ , 52.4℃ , 56.2℃

There is a significant decrease in both CPU temperature and shell temperature.

Is it possible to use 7 holes? I still see 6, this is not enough for a modem, I have to do it manually, 3 for WiFi on one side, two on the other and two more on the other.

I’d like to request an update on the topic. This is kinda „shut up and take my money” siutuation here

11

I’m also interested in purchasing this. Any ETA on release?

12

I would definitely like to see more holes as well. 7 would be the perfect number to run a WWAN card and the wifi.

13

Count me in as another interested party. The default case is really hot and I’m not sure what else can be done with it. Perhaps drilling some more holes in the bottom? Or adding more small copper heatsinks to the chips? It’s like a little furnace in there, even at idle.

14

We still wait for this case :frowning:

15

I am also very interested. I need 7 antenna holes, 4 for the modem and 3 for the wifi.

just contact [email protected] she will full support you for the shell. easy to do sample.
