stavoltafunzia got a reaction from poddmo in 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.

stavoltafunzia reacted to giox069 in NanoPi R2S: lan0 goes offline with high traffic
@Igor disabling tx offload on the USB ethernet (lan0) seems to solve the problem.
ethtool -K lan0 tx off And I can't see extra CPU load or appreciable bandwidth drop with this. Great!
To make it work at boot, i changed /etc/udev/rules.d/70-rename-lan.rules as follows
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="r8152", KERNEL=="eth1", NAME="lan0", RUN+="/usr/sbin/ethtool -K lan0 tx off"
Thank you.
