Possible high temperature - drenedo - 04-14-2021
Hi all,
today i tested the rockPro64. After some time, 30 minutes more or less, I checked the system status and saw the temperature was between 80º and 85º C whit htop command (armbian). The rockPro64 didn't be stressed and the use of cpu was very normal.
I read than 80ºC is a hight temperature for a rockPro64. Anyone have any experience like that? 80ºC is a normal temperature for the rockPro64? Is strongly recommended a fan or a healtsink? Is possible that htop is readding a wrong value? because this situation has no sense.

It does make sense, your CPU will be thermally throttling itself.
You absolutely should have a heatsink on an RK3399 for most use cases. Depending on your heatsink, enclosure and ambient temps a fan is not essential.

It is very strange indeed. I use a heatsink (no fan). Usually I reach this temperature under heavy stress test (CPU test or memtester, note that memtester does not use high CPU). Under normal use I am at 45-50C. Above 80ºC or 85ºC the CPU is throttling (reducing the frequency). I think that a heatsink is necessary for regular use to avoid overheat. It is not difficult to set, not very expensive and worth it. As to the fan, I use an external one only when I perform stress tests.
