Hi all,
As promised here is a pic of the thermal imager - as you can see the vim under load gets to around 62-63 degrees.
This leaves me buffeld, if heat is not the issue then what is the cause of the freezes and why do they stop once the fan is on 
I guess ill have to wait the month untill i get the ttl to usb adaper - not happy.
Thanks again everyone!
It’s really strange, can you confirm again with this? It should be a problem if the temp is 62 degree under load.
And did you try with a new DC adapter?
Hi Gouwa,
Yes, the cpu temp gets to 62 degrees, you say this is too high under load?
And yes i tried several power adapters see pic:
Top to bottom:
There was no difference between them regarding the heat (under the htc the vim was a bit strange but maybe it was too weak).
I think you definitely have a hardware issue, you received a defective board, fan will lower the temperature, the only solution is to contact the seller.
You tried 5 adapters, and Vim didn’t work properly on neither of them, i don’t see any other solution.
Based on my experiences, I’m agree with Tommy… As you confirm, the CPU temp isn’t issues, but there is as well DDR memory. It’s unfortunately native that memory chip are faulty from manufacturing (since ~15years experiences, I can tell you a lot of stories), and are sensitive on temp too. And bad for us, it’s difficult to test in ARM platform.
I’m just tried connect Linux RX/TX console and I’m see there isn’t way to access uboot.
For example, in company what I’m working for, we have kind of memtest included in uboot. Looks like that version of uboot cannot be controlled, or?
If you interest about console, you can use windows like me, the good one console program is putty.exe, speed is working under 115200bps. Power +3.3V isn’t required. But most likely you will get crash dump from kernel and you figure out, that something is wrong, what you already well know.
Oh well 
I guess I have no other option but to contact the seller – I hope they will not give me any problems replacing it.
I hate this sort of things, it is such a hassle.
I just hope the next one won’t have any issues…
If you got any problem, let us know.
And kindly take a Sticker on the VIM device, so when we got the device, we can locate & analyse the real issue and post the result here.
Thanks!
anche a me arrivava a 80c poi ho cencato di capire dove fosse il problema e o scperto che
temp cpu libreelec 52c
temp cpu andoid kodi CPU 82c
temp cpu android spmc 64c
tutti provati con stesso file video e per medesimo tempo
temp linux ful load 68c
Hi qaz22,
I’m not sure how accurate these reading are – that is why I used the thermal camera.
When checking android or kodi I saw temperatures of 85 degrees and on the thermal camera it was 62 degrees.
I wish there was a reliable on-board sensor, it would have made everything easier (not everyone has a thermal camera lying around…)
Touching the box between android and libreelec codes and linux the difference is felt with linux and libreelec the box and practically tepid
With android codes the box is really hot, however you can do the same test.
I asked my friend for the thermal camera again, i will do another test with libreelec over the weekend and update with the results.
I was also interested in why and with android that temperatures rise with Asphalt 8 same code temperatures. I come from the use of a p30 raspberry that warms a lot and the temperatures are the first thing I control and I set up by mounting a really big heat sink , quet
These types of products all suffer from the same problem
I tried this app (CPU Thermometer), but all I get is… “Important Message: We are sorry, but CPU temperature sensor isn’t detected on your device”. Before I upgraded to V171028 from V170930 the sensor worked fine with the CPU-Z app. Any explanations? Any advice? Also, for the first few boots after upgrading, my boot screen, the Khadas screen, not the Android boot screen, was green, not black as before. Now it is black again. I want my Temperature reading to work again so I can hook up the blower fan to the fan header instead of the 40-pin header.
Device: VIM2 Max with S912, 3Gb RAM, 64Gb eMMC
OS: Android 7.0.1 Nougat_V171028
Hello, My VIM2(same config as yours) is running the same firmware. I am using this temperature app. I like it because it has an optional floating widget to overlay temp readings.
This app is displaying temperature as expected. Based on when the fan turns on, displayed temps mirror my fan settings.
CPU-Z also displaying temps.
I don’t have either of my fans connected to the fan header, so my fan would be on permanently. What would have stopped my temperature output? Before I upgraded I had pressed all the buttons to reset the chip. I have the log from the upgrade. I erased the whole device I think before the upgrade, unintentionally, but all seems well except for the temp reading. Would it have anything to do with the Uboot I keep reading about? Or is that Linux. I’m stumped. All I can think is I need to reinstall or flash the whole device. But I want it to work so I have to do something
Hi, Rocket99:
How you erased your VIM2 device?
When I went to USB install the upgrade there was an option to check boxes in the configuration of USB Burning Tool,. and I was instructed by the OP of the pp0 only, to Erase flash, and, Erase bootloader, which were already checked by default. The Reset after success, and Overwrite key boxes were not checked and I left them that way. Been wondering, is the latest upgrade just a dirty flash update, or, is it a complete ROM?
I flashed the latest update to a VIM2 that had Ubuntu installed prior. Not sure I follow the term “dirty flash update”, but seemed a complete ROM to me. Flashing the image will erase user data, apps, and app data. I assume this is a “clean flash”. 
The following image shows the configuration I use to flash, some choose to go with the defaults. I make a single change. I have used both successfully, but I flash all of my AML devices with this config…
Does anyone know what to do with the blue square you get in my heatsink pack brand new and we all have learn
