Nanopi 2 cpu temperature

Wenqi
Hi, have anyone notice the temperature of the nanopi 2 cpu. It's getting
extremely hot when streaming videos. The system reboots automatically after
a while. Don't know what's the normal operating temp for this chip.

NanoPi 2 was next on my purchase list.

I have two NanoPC-T1s and one would overheat and shutdown just running a
Ubuntu desktop, ie no streaming video.  It recovered a few times then
finally said, "I quit".

Before you lose yours maybe try a stick-on CPU heatsink and make sure you
have a good airflow around the CPU.

I have read comments that as these parts are used in mobile devices so they
should be able to survive, but maybe people are NOT streaming videos like
you are!

See what Odroid do on the their product.

Thx dave, I actually had a small heatsink on it already. Unfortunately, the
temp is still over 60C when CPU/GPU is running on full. I guess a fan is
the only solution left.

The nanopi 2 board is very powerful. The only problem I have with it is its
board design. The cpu chip is slightly lower than the surroundings which
makes it hard to add big headsinks. Maybe in the next version, friendlyarm
will have better designs.

Cheers,

A fan, even on a small (stick-on) heatsink should make a significant
difference. 

Does the unit still shutdown with the small heatsink?

Wenqi
No. Just a bit laggy sometime.

Datasheet page 43-3

  Operating ambient temp  TBD

Went back to the S3C2440 used in the mini2440

  Operating temperature TOPR Industrial –40 to 85C

However, that doesn't tell you anything about the temperature on the chip.

Some high-end processors have on-chip temperature measurement and I thought
the ability to turn down clock speed to reduce power consumption.  Couldn't
see any mention of thermal management in the datasheet.

I know that would probably NOT make for a good video streaming experience!

You say space is tight.  How about a small piece of copper or aluminium
plate to act as a spacer to a suitable heatsink that you could mount a fan
on?  Also, thermal compound or thermal pads between the various interfaces.

Wenqi
Thx Dave. Great suggestion. I'm working on an metal enclosure for the
nanopi. I'll use the enclosure itself as the heatsink. I guess that shall
be enough.

davef
To use the enclosure, as a heatsink, you will need a good thermal path
between the CPU and the case and the case will need to effectively get rid
of the heat.  A challenging thermal problem.

... a bit laggy ... maybe the throttling is working.

hello,
     
There are the  results of nanopi 2 high and low temperature test (have a
mouse and HDMI connected to):

--low temperature  –40°C (24 hours) normal. NanoPi 2 can normal work  in
low temperature. 

--high temperature 80°C (48 hours) normal ,90°C (48 hours) normal. NanoPi 2
can normal work  in high temperature.
