strange behaviour on newer kernel - tuxd3v - 10-05-2018 Hello, I noticed that after upgrade to: linux-image-4.4.154-1122-rockchip-ayufan-g7859b9b904a9 linux-headers-4.4.154-1122-rockchip-ayufan-g7859b9b904a9 linux-firmware-image-4.4.154-1122-rockchip-ayufan-g7859b9b904a9 My Fan stop and start, almost by itself.. Does anyone is experiencing the same? I am um the bionic image.. RE: strange behaviour on newer kernel - tuxd3v - 10-06-2018 (10-05-2018, 10:44 PM)tuxd3v Wrote: Hello, Something that occurs me.. It could be that this newer kernel, only activate Fan, when temps reach 57°C .. Because the hwmon facility, has 3 or 4 options.. which include Throtling, and Active Thermal And so maybe it is a feature..??

For example in fanctl I start it like: 130 200ms 190 1 second so that it can gain momentum, then I set the pwm to a value, imagine 40. The fan already started it can then be at 40.. I don't advise going lower than 30-35, it depends again.. because of it, I choose 40 as minimum.. |
