Banana Pi R3 vs RPi4 for router

Two thoughts on passive cooling.

Create a chimney effect by vertically mounting the board. Hotter air rises out vents in the top and pulls cooler air in through bottom vents.

An alternative is to thermally couple to the case to increase the surface area.

Heatsink + fan is recommended , the bpi r3 enclosure has not vent, with the passive cooling temperature will raise over 75C , I have 60 x 60 x10 mm heatsink with a small fan on the top, this are the last 6 day stats

i guess the fan is noisy isn't it ?

I can't comment about the bpi r3 heatsink + fan they are selling now, I use 2 pin low noise fan, almost imperceptible. 3 pin fan are controlled by the temp and not always are running so they are more quiet.

Does the Bpi R3 has a supported HW offloading like MT7621/MT7622 ?

I just found the datasheet, so i guess YES ?

Check this thread: Use mtk sdk HWNAT driver to replace hw flow offload

Unfortunately, I've never managed to compile firmware, so this is not a solution for me... :sob:

well i found the answer here :

How did you add the Thermal Sensor to Statistics?

i have a few glitches in thermal zone, what should be in these locations? a graphic?

And in "sensors", the temp in the 1st graph can't be that low, it's +20°C in my room.

The sensors wrong temp reading is an old issue, hasn't been fixed
For the glitches in thermal zone, the plugin can configured with just the active thermal zone.

This, I need to know if it can route 1 Gbps WAN with SQM and if there's come CPU left over after.
I will be turning off the wifi as I don't need it.

Just run a two minute test that will generate the load and test latency under load:

i have a 2Gbps/1Gbps fiber line. without QOS, i get a A on
In my case, it's not worth installing QOS just to go from A to A+. On a DSL line, I can easily understand why it's useful if several people use the Internet at home, but on a fiber line, I think it's unnecessarily complicating the network. I'd rather stay without QOS and have HW NAT acceleration enabled.

Hi, just curious on what tape you are using on the wires above the heat sink. Is that EMI/Shielding tape? If so, is it available on amazon?


Its just heat isolation tape, commonly used for hot air soldering task. Don't know if it provides any help with signal, I just wanted to make sure the wires wont get heat from those chips.

Unfortunately, my 1 Gbps line is pretty loaded to start with, it serves a few TB of traffic / month. I usually get an F in bufferbloat tests so gaming feels terrible.

I don't want to spend on a router that can SQM Gigabit or even two, I need to.

Sometimes it might be just too much open connections (e.g. torrents).
I can also get > 1T traffic on my 1G line, without SQM the only thing needed is just a faster CPU (I previously tried to use my Synology DS1621+ with 2 core assigned to VM and it worked perfectly)
