Hello,
I have 2x CRS317 switches, and they (arguably) run fairly hot.
First one (running 6.47.2)

Currently Zabbix is giving some “overheat” alarms from them when they reaches 50 degrees, yet the fans are not spinning. The fans spin fine and move air when the devices boot, and the fault led is not active, as I have understood the fan-bug I’ve read about would have caused?
As these are rack mounted in server room where noise is not much of an issue, I would really prefer the fans to run all the time, by example i have couple CCR1016’s where the fans run all the time..

I have tried fiddling with the /system health use-fan=on, and attempting to modify the various threshold, as well as upgrading routerboard firmware and RouterOS, and have also tried running “detect fans”.. and while the fans spin just fine during boot, as soon as the devices have finished booting, they stop. Some searching on this forum seems to indicate there is no way to change or modify these settings on a routerboard device?
Are my fans bugged out or is simply the thermal threshold really set so high on these devices?
