New OPi Zero - Yet another high temperature issue...

Question

My third Orange Pi Zero came last week, yesterday I plugged it and had heating issues... So I started reading, learning and testing....

 

Setup:

  • OPiZ-1: 256 MB, no SPI flash - Has extension board plugged - for comparison
  • OPiZ-2: 512 MB, with SPI flash
  • OPiZ-3: 256 MB, with SPI flash (new one with problem)

 

Test conditions:

  • All with (newish) Sandisk Ultra 16 GB Class 10
  • All new formatted (SD Formatter) and burned/validated (Etcher v1.0.0) with Armbian_5.25_Orangepizero_Debian_jessie_default_3.4.113.img
  • All on my desk - side by side, ambient temperature 25.0-25.1 C (20 cm from boards, no air flow)
  • No case, no passive/active cooling
  • Power supply 7 port 5V 36W total, 2.4A per port (wait, wait, I tried others, separated etc - I'm testing them with USB V/A/W tester - 5.2-5.3V / 0.260-0.350 A)
  • First install done, rebooted,   apt-get update && apt-get upgrade'd, rebooted, tested

 

The results are given below...

 

I switched (i.e. reformatted/reinstalled) the SD Card of OPiZ-3, no change...

I plugged OPiZ-3 alone, no change...

I used 3 other power sources, no change...

 

Is the new OPiZ-3 a faultly board? What else can I test/check?

 

Thanks...

How are we doing at this moment, referring to the newer OPi Zero LTS

It states " low running temperature and low power consumption. ", but ... ... ?

Anyway my goal is to run domoticz, which will be connected to my smart meter in the meter cupboard

So, I just got mine a few days ago. It's the OPi Zero LTS 512mb version. The board states it's v1.5.

 

I have it running Pi Hole with around 2 million blocked hosts and it's around 20C. Before installing anything (PiHole), even with passive heating it was well below 10C (Only had Armbian). I'd say it's pretty good. Max I have seen it hit under some load is 33C.

 

Edit 1: I just installed a heat sink and can already see the temperatures are lower than before.  With heatsinks I'm now at around 13C and don't go over 26C when it's under load. Pi Hole isn't super intensive on the CPU anyway but still. 

 

Edit 2: I think it's also worth mentioning I have mine in a case.

Edit 2: I am going to install PIVPN today and set up remote access to it via xrdp and will see how it goes with temperatures. Once I get home, I will post a temp log. 

 

Below 10C? Around 13C?  What's Ambient, 0C?  You keep this outdoors, in the Arctic? :huh:

Here you go. I also couldn't believe it. Maybe the sensor is faulty? I live in Russia and the temperature is 0C outside. Room temperature is around 26ish.  Also, I edited my post to make things more understandable. I was at around 10C when only Armbian was installed (no heatsink). Then once PiHole was up, I hit around 20C (still no heatsink installed). Then I installed the heatsink and went down to around 13C from 20C.  As I previously stated, mine is indoors.

I can confirm that new Orange Pi Zero LTS H2+ has SoC temperature reading faulty. I just swap OPi version 1.4 with LTS one and temperature "dropped" from 52 degrees to 10 and then slowly reached cca 18 degrees, which is really hard to believe. I'm suspicious that Xunlong simply adjusted firmware get better results...

that's what i'm saying - SoC temperature reading in new model is inaccurate.

 

Figured as much, looks like they are indeed messing with something to make it look like temperatures are less. Don't have an infrared thermometer to test temps at the moment though. I'll try and get one soon.
