Depends on whether you're on AMD's virtual degC scale they use for their CPU
temps or it's real degC's.
Also, if we assume that the dbcool chip controls the CPU fan(s), it makes more
sense for it to measure the CPU temp than the VRM temp, right?
sysctl hw.dbcool0 gives
hw.dbcool0.l_temp.Tmin = 90
hw.dbcool0.l_temp.Ttherm = 100
hw.dbcool0.l_temp.Thyst = 4
hw.dbcool0.r1_temp.Tmin = 90
hw.dbcool0.r1_temp.Ttherm = 100
hw.dbcool0.r1_temp.Thyst = 4
hw.dbcool0.r2_temp.Tmin = 44
hw.dbcool0.r2_temp.Ttherm = 57
hw.dbcool0.r2_temp.Thyst = 2
hw.dbcool0.fan_ctl_0.behavior = manual
hw.dbcool0.fan_ctl_0.min_duty = 27
hw.dbcool0.fan_ctl_0.cur_duty = 100
hw.dbcool0.fan_ctl_1.behavior = manual
hw.dbcool0.fan_ctl_1.min_duty = 27
hw.dbcool0.fan_ctl_1.cur_duty = 100
hw.dbcool0.fan_ctl_2.behavior = manual
hw.dbcool0.fan_ctl_2.min_duty = 27
hw.dbcool0.fan_ctl_2.cur_duty = 100
but that's with BIOS CPU fan regulation disabled.
> Is there a dbcool1 r2_temp with a similar value and limits?
No dbcool1. But I only have one CPU installed on that board.

Yes, of course. I was wondering where that limit came from.

I'll have a look (I will need to physically go there or can I read this from some dmesg or sysctl?).
