Cooling the board
Due to the absence of heatsink mounting holes on this board, it’s essential to apply a high-quality thermal paste to ensure optimal heat convection contact. Since the lake features an onboard 5V power source, the only option left is to go with the passive heatsink. You can select larger heatsinks based on how tall the case is.
Below is a list of recommended heatsink sizes.
| No. | Component | Heatsink dimensions |
| 1 | LPDDR4X Memory Chip | 15x10x5 mm |
| 2 | Ky X1 System on Chip (SoC) | 20x20x10 mm |
| 3 | PMU Chip | 6x6x5 mm |

Temperatures
So, we checked the temperatures, and they’re hanging around 57°C. Even with the heatsink on, it’s pretty hot but still manageable, and everything seems to be running fine. But keep in mind, once the board goes into a totally closed case, those temps could go up even more. A smart move would be to design a case with an opening right above the Ky X1 Chip, or even better, use an external power source and slap on a small fan to help push that extra heat out. By the way, we already mentioned that Orange is expected to sell a metal case for the board soon, so if you can hold on to a bit, it should be available in a few weeks.
Where did you get the case? I’ve looked everywhere on AliExpress (well, not *everywhere*) but have not been able to find any suitable case or even a drawing for a 3d printer.
It’s not a perfect fit. You will find it on AliExpress. just search for “acrylic case orange pi 4a”.
Thanks for the tip but I can’t find the case under that name, also the pi4a has a whole other ports layout. Would you have a direct link?
The Orange Pi R2S Case is currently in production. If you were referring to the case for the RV Board, I’ve updated the article to include a direct purchase link from AliExpress.
I’m still looking for that case and can’t find it in your article? Can you just give me a link? Thanks
I’ll check with the company and get back to you with an answer in a few days, as it’s currently Chinese National Day.
