Normal operating temperatures ? - ilovegentoo - 11-04-2018
Hi everybody,
I just tried my new rockpro64 4GB board and I installed the 30mm tall heatsink to see how it performs (no fan).
After about 5-10 minutes of stress test using sbc-bench.sh -T 80 I found it to reach 75 °C.
At idle it is sitting at about 43 °C (still passively cooling 15 minutes after the end of the stress test)
The heatsink was installed using some NOCTUA NH-H1 thermal compound I had laying around (I didn't use the thermal pad since I thought that heat transfer would be more effective using standard CPU thermal compound). A very thin layer of thermal paste was applied on all the middle ("raised") surface of the chip.
Do these temps look normal to you? I just did a basic Debian 0.7.9 SD card install.
Thanks

Any CPU when pushed by longer periods, will rise its temps..
In my opinion, that temps should not be good continuously,
Without a Fan, the thermal compound you used its ok.
RockChip says its rated to max 85, but it also says that at that temps CPU will do a emergency shutdown.
For reliability you shouldn't be using that temps, continuously..
The better option is a fan above it..
BUT if you put a Fan,
IMO should use the thermal PAD, because the thermal pad serves has a vibration absorver for the fan.

I guess it's highly reccomended to use a fan anyway ....
I'll install these Rockpro64 boards on a 19'' rack shelf with 120mm fans delivering high airflow
EDIT: Just wondering about another thing though ...
Do I also need to cool the 2 rectangular ICs near the CPU or it's not required? At the moment I have the CPU heatsink hanging about 1mm over them

Yup pretty much the same temps here. (Was also using sbc-bench - cpuminer is what runs with the -T option.)
