berobispo Posted July 12, 2020 Share Posted July 12, 2020 Armbianmonitor: http://ix.io/2rsT Hi! my nextcloud instance on an odroid hc2 running armbian has been running stable and smoothly for several months now. Thanks Igor and the whole armbian team! I have one question though: Task: I convert videos with ffmpeg to reduce file size and optimize them for streaming observed behaviour: the CPU is getting very hot! In the evening up to 100 °C (see below), but at noon I have seen temperatures of up to 115 °C! I read somewhere that 110 °C is the critical temperature for the board and the stock hardkernel image has an emergency shutdown implemented. But my board running armbian seems to be negligent of this. On a side note, the CPU frequency reported in armbianmonitor -m is 1800/1300, in htop all 8 cores show 1300 ( .LITTLE)? expected behaviour: shouldn't the CPU be throttled automatically? excerpts from armbianmonitor -m: Stop monitoring using [ctrl]-[c] Time big.LITTLE load %cpu %sys %usr %nice %io %irq CPU C.St. 17:56:51: 1800/1300MHz 2.20 2% 0% 0% 1% 0% 0% 84.0°C 2/13 17:56:57: 1800/1300MHz 2.99 93% 0% 17% 75% 0% 0% 87.0°C 2/13 17:57:02: 1800/1300MHz 3.79 93% 0% 18% 74% 0% 0% 89.0°C 2/13 17:57:07: 1800/1300MHz 3.89 82% 0% 13% 68% 0% 0% 84.0°C 2/13 17:57:12: 1800/1300MHz 3.74 80% 0% 18% 60% 0% 0% 85.0°C 2/13 ... 17:59:19: 1800/1300MHz 9.83 90% 0% 16% 73% 0% 0% 98.0°C 2/13 17:59:25: 1800/1300MHz 10.38 95% 0% 15% 79% 0% 0% 99.0°C 2/13 Time big.LITTLE load %cpu %sys %usr %nice %io %irq CPU C.St. 17:59:30: 1800/1300MHz 10.27 94% 1% 22% 70% 0% 0% 100.0°C 2/13 17:59:36: 1800/1300MHz 9.85 90% 0% 16% 72% 0% 0% 99.0°C 2/13 17:59:42: 1800/1300MHz 10.10 95% 0% 17% 77% 0% 0% 100.0°C 2/13 17:59:48: 1800/1300MHz 10.33 98% 0% 18% 79% 0% 0% 102.0°C 2/13 17:59:54: 1800/1300MHz 10.38 95% 0% 22% 71% 0% 0% 101.0°C 2/13 18:00:00: 1800/1300MHz 10.79 97% 1% 20% 75% 0% 0% 100.0°C 2/13 0 Quote Link to comment Share on other sites More sharing options...
jshc1 Posted August 28, 2020 Share Posted August 28, 2020 My HC1, after exceeding 110, just went out. I'd rather avoid going over 100. With a well-matched kernel has 1500 and 2000 on the BIG. When all the cores are working intensively, samsung heats up very quickly and is just reaching those 90-100C. Much depends on the ambient temperature and HDD / SSD. This passive cpu cooling is very inefficient. If you often have a large load, think about a fan. Also make sure you have scaling_governor on demand. Mine in the area over 60 starts to go down to 1400/1900 - 1300/1800 and so on ... You can also check if the cpu touches the surface well, or replace the thermo pad. 0 Quote Link to comment Share on other sites More sharing options...
