CPU temperature monitoring trouble

[adelejjeh]

Hello All,

I'm new to freeNAS so please bare with me. I have an old desktop lying around, its a pentium 4, 3.6GHz, so I decided to try to make it a NAS using freeNAS. I wanted to monitor my cpu temp, so searching over the internet I found that the "sysctl -a" command should give me the cpu temperature. However, I tried it with "grep temp" and all the other formats that I found online but it seems as if the command isn't returning my cpu temperature. All I get when I enter "sysctl -a | grep temp" is some information related to ipv6 adresses. Is there any application that I can install or something? I would appreciate any help.

Regards
Adel

I don't have any idea what your problem is.. when I do sysctl a | grep temp I get:

Code:

I assume you don't get any temps if you do:

Code:

sysctl -a |egrep -E "cpu\.[0-9]+\.temp"

My first guess is your motherboard doesn't support reading core temps in FreeBSD.

My first guess is your motherboard doesn't support reading core temps in FreeBSD.

I only get the first five lines. And ya, when I use the second command I get nothing. What's the solution?

Try a different motherboard? Maybe update your BIOS? It should work. My guess is your hardware doesn't support reading the CPU temps from FreeBSD.

It'd be a lot simpler to diagnose if he'd just share which motherboard he has. I found out awhile back via google it didn't work for the E35M1-I motherboard I have. It was an "AMD thing" (yes, you can add that to your list :) ).

Motherboards with Pentium 4's on them tend to have unusual or none built-in temperature monitoring.
Is your machine hot? If not, just go on without monitoring the CPU temperature.

Hey guyz, sorry but I've been off the grid for a while. I've been having problems with my phone and I was busy solving them. Anyway, my motherboard is an intel D946GZIS desktop board. As I said, this is an old system lying around.

Actually, the reason I want to monitor the temperature is cause the bios hardware monitor gave me a temperature reaching more than 90 degrees. I bought a new fan and installed it, the temp now is reaching the high 80s. I don't know if it's normal to reach such temperatures in the BIOS that's why I wanted to monitor the system during FreeNAS operation.

 

[cyberjock]

Is this 90C or 90F? Anything above 80C is dangerous for the CPU. In the BIOS I'd expect temps in the 35-40C. If you are getting anything above 45C you have inadequate cooling for the CPU. May be improperly installed, the CPU heatsink compound may not be properly applied, etc.

Code:

[root@freenas ~]# uname -a
FreeBSD freenas.local 9.3-RELEASE-p28 FreeBSD 9.3-RELEASE-p28 #0 r288272+f229c79

Guys, how can I get CPU temp?
sysctl -a | grep temp returns nothing about CPU:

HW is GA-G31M, Intel E5400

 

[SweetAndLow]

Hardware might not be supported.

 

[mammuthus]

So what solution?

 

[Mirfster]

Let us know what hardware you have and maybe you can get a clearer answer?

HW is GA-G31M, Intel E5400

What additional info you need? MB is Gigabyte GA-G31M and CPU is E5400

 

[Mirfster]

Opps, didn't see you posted that earlier my bad. Quick attempt to lookup that board shows multiple revs and models. Any chance you know what model/rev your board is?

I know this is old but: It is not useful to say "It works on mine" "Why doesn't he ..........." He already said he is new.

So why the post?

For that board you may need to load a coretemp driver.
