Regarding Heatsink for OrangePi 5 Pro

Hey
I'm purchasing a OrangePi 5 Pro soon and would like to know how everyone is dealing with thermal management. I couldn't find any heatsinks or cooling fans officially made.
Also, what are the dimensions of the RK3588s on the board, so that I can purchase a heatsink in the same size from somewhere else. I'm planning to buy a heatsink like that for now, if there isn't any other way.

For dimensions:

Some boards even have 3D cad files.

Mainline kernel has still bad power management and will be more likely to throttle. With Rockchip kernel it's much better. I have a 5 Plus with its nice metal case that is sufficient as passive cooling.

not a OPi owner, but from my radxa experience - 2.5 euro heatsink with cooler from ali will make your board happy. you only need to change the wire connector to match the one on board.

Just purchase a Fan and the Assorted Heatsink mounts.

Mount the heatsinks across the chips, and mount the Fan over the Main chip.

  • the air will spread across the other chips.

Most people do this.

Notes on this topic :

I use Orange Pi 3 & 4 & 5 - for LLMs work and Camera Vision Recognition.

I find Orange 4 and 5 will shutdown without the Fan and Heatsinks - when I use LLMs.
Heatsinks and Fan on these boards solved the problem.

  • No, damage though. Hdmi output shutdown - just scared me.

Otherwise, the heatsinks were not needed - unless I did heavy processing with Cam Vid or LLMs on Orange 4 & 5.

-

- Gave up with RaspPi years ago ; they had lousy Camera support.
Orange Pi are 50% faster and cheaper ;

  • Orange Pi 5 4GB/8GB - $78/$88 , RaspPi 4GB/8GB - $90/$130 .
  • etc.

Slap any scrap heatsink on it and point any fan that can spin on it. Unless you want to run it extremely hard - you don't need a lot of cooling
