[Nanopi R2S overheating and throttling]

This is the final solution I ended up with: metal case + old 939 stock cooler.

.

 

 

I was not totally satisfied by the metal case only, probably also because I keep the nanopi in a closed environment with no air circulation. Previously I tried also the heatsink with the small fan, but it's rather noisy and doesn't help a lot if you still use the yellow case.

Received my SBC today, installed armbian and run quick tests

Runs very hot (in stock yellow case). Throttles under load and can not run at full 1500Mhz

Below results on armbian measured with armbianmonitor -m

power measured from the wall

71C / 2.5W / 600Mhz idle

85C / 3.7W / 1000Mhz under load (stress -c 4)

 

I also tested without case and results are better but still it throttles under full load. Ambient temperature was about 25C

Is this just me and my unit has faulty heatsink or you also observe similar results?

Any ideas on how to fix this? I see there is a fan header on the board but no fan installed, just the heatsink, but I think the better solution would be to use a metal case that acts as a heatsink. (like Flirc for raspberry pi)

 

I'm experiencing similar temperatures with the yellow case. I checked the board and the thermal pad adheres well to the soc and the heatsink. I think the only solution indeed is the aluminium case. I ordered one few days ago, but still it hasn't arrived yet so cannot say anything about its performance.
