Barebones CPU temp display pets

[ozsouth]

Varying systems have different requirements, so maybe either of these CPU temperature displays could be helpful. Use at own risk.

You can make a desktop icon. For cpu0temp, when installed, in filemanager go to
/usr/share/applications/pssct0.desktop & drag it onto main desktop. (for cpu1temp, use pssct1.desktop).

Tried the cpu0temp one in BookwormPup64.

It works Ok.

But sure is a very barebones display.
Have to click on menu entry to run it.

Yes. You can make a desktop icon (see edited 1st post).

@ozsouth / @bigpup :-

You could of course set this to run from an icon in the notification area. I do this a LOT for various wee utilities.....like the spot-to-root permissions changer for moving stuff in and out of spot, or the Inxi 'portable' systems profiler I posted about the other day (to name but a few). Fred and musher0 figured it out for me a few years ago, and I've re-used it in modified format for no end of things.

===============================

One thing to note; my own Pentium "Gold" G5400 - an 8th/9th-gen Coffee Lake-architecture Intel chip - doesn't use either of the above functions. It uses

Code: Select all

thermal_zone0

....and

Code: Select all

thermal_zone1

Out of the two, I've always found "thermal_zone0" to give by far the most accurate reading. This quite possibly applies to the immediate predecessors/successors.....the Kaby Lake/Sky Lake, and Cannon Lake/Whiskey Lake architectures. Just thought it worth mentioning!

@mikewalsh - yes, that's why I said 'could be helpful'! I'd be interested to see what the output of the main script is on your pc. If you run (in terminal): /usr/local/Pup-SysInfo/func -sysinfo_sensors
then look at the contents of: /tmp/sysinfo-sensors
all will be revealed (hopefully!)

Hm. Interesting.....

I've been in my much-modified Slacko 560 the last few days. When I first tried these out, yesterday, I wasn't getting any readings at all. Further investigation revealed that the version of PupSysInfo that came with this, OOTB, was version 2.3; it appears that at this point in time, Roger's build didn't include some of the stuff in later versions. /usr/local/Pup-SysInfo/func -sysinfo_sensors didn't exist; hell, /usr/local/PupSysInfo wasn't even there!

So, I've installed a later build I've had kicking around for ages.....version 2.8. This includes the necessary extra stuff, and the readout from /tmp/sysinfo-sensors gives the following:-

Code: Select all

temp1 (nouveau) : +43.0 C (high = +95.0 C, crit = +105.0 C)
Phys 0 (coretemp) : +37.0 C (high = +78.0 C, crit = +100.0 C)
Core 0 (coretemp) : +36.0 C (high = +78.0 C, crit = +100.0 C)
Core 1 (coretemp) : +35.0 C (high = +78.0 C, crit = +100.0 C)

Now; both gKrellM AND micko's pcmcputemp agree on the same reading, using thermal_zone0. Curiously, this is around 5 degrees lower than the reading delivered by pssct0.....so I'm wondering just how "accurate" thermal_zone0 actually is!

(Ah. ATM, pssct0's readout is now within 1 degree of the thermal_zone0 readout, so.....I wouldn't like to say. My interpretation is that thermal_zone0 is using the 'onboard' sensor within the CPU cores, whereas thermal_zone1 typically reads several degrees cooler, so is I believe reading from the sensor in the socket itself.....)

With me so far? (Huh. pssct0 is now back to 5 degrees warmer. Not sure what's going on there. Any ideas?)

Admittedly, most PCs have several different sensors, both in and around the CPU socket/CPU itself. It IS a job to know which one is the most accurate OR which one to actually use.....and these things can only ever give an approximate reading, at best.

Strangely, pssct1 gives me the GPU readout! This is the first line of the sysinfo-sensors stuff in /tmp, so.....??

@mikewalsh - pssct0 's readout should be closest to the mark. pssct1 is really for when that doesn't work. The idea is to give a fair guide, i.e. if you think your cpu is running hot you can basically confirm it. I find my i5 can jump 15C with some webpages & drop back when loaded, using poorertcputemp1d display. With fans & passive cooling, temp can vary a lot. Even the gpu temp is a rough cpu figure (usually a bit higher).
