Are PCH temps around 70C to 78C normal on a Netgate 1541?
-
My CPU Core temps are all at 48c and my PCH temperature is around 70c to 78c. According to the thermal graph I'm in the critical zone (which the PCH Critical is set to 70). I cannot find operational temperature for this system; All I'm finding is the environmental temperature which is 10c to 35c. Is the PCH temperature being 70-78c running to hot? If someone has/knows the operating temperature for this unit can you please share?
Current threshold values:
Zone Warning: 60c
Zone Critical: 70c
Core Warning: 60c
Core Critical: 70c
PCH Warning: 60c
PCH Critical: 70cThese thresholds seem a little low, but I cannot find operation temperature to set them to the correct value.
Thank you!

Yes, the values reported by the PCH driver on the 1541 (and 1537) are high. That is normal on those platforms. I'm not sure it's valid.

Run "sysctl dev.pchtherm" command, that should give you more info.
.ctt is the critical shutdown temp
.t0temp is the upper limit of "normal" temp (my guess though)The PCH should should be able to handle 100°C easily.
In my system the PCH usually sits between 50°C and 54°C, so I have set PCH Warning to 70°C and PCH Critical to 90°C.

Here are the results from running the command
dev.pchtherm.0.ctt: 130.0C
dev.pchtherm.0.talv: -50.0C
dev.pchtherm.0.tahv: -50.0C
dev.pchtherm.0.temperature: 74.0C
dev.pchtherm.0.pch_hot_level: -50.0C
dev.pchtherm.0.t2temp: -50.0C
dev.pchtherm.0.t1temp: -50.0C
dev.pchtherm.0.t0temp: -50.0C
dev.pchtherm.0.pmtime: 1
dev.pchtherm.0.pmtemp: -50.0C
dev.pchtherm.0.%parent: pci1
dev.pchtherm.0.%pnpinfo: vendor=0x8086 device=0x8c24 subvendor=0x15d9 subdevice=0x086d class=0x118000
dev.pchtherm.0.%location: slot=31 function=6 dbsf=pci0:0:31:6 handle=_SB_.PCI0.TERM
dev.pchtherm.0.%driver: pchtherm
dev.pchtherm.0.%desc: Haswell Thermal Subsystem
dev.pchtherm.%parent:So 130°C is the critical shutdown temp and 50°C is the normal temp?
If that is the case then should change PCH Warning to 80°C and PCH Critical to 100°C or should change PCH Warning to 100°C and PCH Critical to 120°C?
Thank you!

I would say that the shutdown temp is 130°C
Those values that say -50°C are probably unsupported by that chipset.
T0-T2 are some kind of throttle states, if I understood the Intel datasheets correctly.Temperature Widget max threshold is 100°C, so you can't go over that without editing files (and those would reset on every upgrade)
If you have temperature history for PCH and in long term it stays on the 70-80°C range, I would probably set the warning at 80°C or 85°C and critical at 100°C -
Thank you, that makes sense. I didn't catch the - sign in front of 50.0C.
I don't have any historical data on the PCH temps, I'm going to have to set something up. Doing a quick search on it, looks like I'm going to need to use SNMP and something like Prometheus with some other tools to get this information. Unless you know of a better way to get this information?
Thank you again for all the information and help,

You should be able to get history data from pfSense's built-in monitoring.
Status -> Monitoring,
Click the wrench icon on top right here you can specify System/Thermal Sensors
If you click Show Advanced, you can create more view tabs for different graphs if you want. -
That does help a lot, unfortunately the System/Thermal Sensors doesn't report PCH temps on the graph, just has the CPUs. I will look into this further to see if I'm missing something.
Thank you!

You'd have to reset the thermal sensors RRD data to start logging that if you just upgraded and are now seeing the PCH device.

That did the trick.
