How hot is your your Pentium M ?

-=Graz=- · 03-20-2006, 03:32 AM

HI All,

Just wondering what temperature other users Pentium M processors run at? (shipped w Centrino)
Back when i used to play w.desktops a good temp was between 35-40 degrees celcius (In Australia)

This unit sits at around 50-55 Degrees..
The cpu fan works and regularly turns off or slows down.. just wondering about you guys?
It seems kinda hot to me... this is with no load on the system.. just browsing 1 x webpage etc..

Pentium M (Banias) @ 1.8Ghz

Hmmm.. i prob should have posted this in Hardware but the Slack forum seems like home now...

Code:

$ cat /proc/acpi/thermal_zone/THRM/temperature
temperature:             49 C

$ cat /proc/acpi/thermal_zone/THRM/trip_points
critical (S5):           105 C
passive:                 99 C: tc1=0 tc2=9 tsp=50 devices=0xc14d3ce0
active[0]:               45 C: devices=0xc14d3a60

$ cat /proc/cpuinfo
processor       : 0
vendor_id       : GenuineIntel
cpu family      : 6
model           : 13
model name      : Intel(R) Pentium(R) M processor 1.60GHz
stepping        : 6
cpu MHz         : 598.292
cache size      : 2048 KB

This is with not much to do for the cpu - so the frequency is down to minimum - but it never got hotter than just under 60 degree celsius

you guys are on fire! mine is at 30-35 idle and goes at 45-50 C on full load on a Pentium M 2 GHz

...not that I'm worried - it is a quite thin laptop (Samsung P35) and the environment is at about 21 degrees.
The fan runs at low speed almost all the time - see the trip points...the heat might get easier out of your machine - not much I can see to do about it to change that - or do you know...?

my M770 runs at 45C idle and up to 100C when compileing hard core. For somereason i think that its not really 100C but 100% the temp it can take.

Here's how I set mine: (Put in /etc/rc.d/rc.local )

Code:

# Set the trip point temperatures (in Celsius)
    echo -n "100:0:90:80:58" > /proc/acpi/thermal_zone/THRM/trip_points

    # Activate the temperature control system of the kernel
    echo -n "30" > /proc/acpi/thermal_zone/THRM/polling_frequency

    # Turn off the fan
    echo -n "3" > /proc/acpi/fan/FAN0/state

As you can see, my fan doesn't even turn on until 58C. I do mess with it every once inna while. I needed the above because otherwise my fan was on all the time. You can change the trip point to what you want, but make sure you keep all five.

Pentium M 725. 1.6 GHz. Toshiba Satellite A50.

-When the fan is not running, it's less than 55°C.
-When the fan starts running, it means it has reached 55°C and it's cooling down.

So far I haven't had any problems

well looks like Pentium M tends to work really freakin' hot!!

on my laptop (HP pavilion zv5200) I got an AMD AthlonXP 3000+ ~ 1.8 GHz and never gets hotter than 65 °C even when I'm playing (UnrealTournament, UT2004) for several hours, when idling it's only at 30 - 35 °C

on my desktop machine (built by myself

; has a lot of ventilation) I got an AMD Athlon64 3700+ ~ 2.2GHz and idle is at 25 - 30 °C and gaming (Doom3, Quake4) is at 55 - 60 °C

I just wanted to share my facts, not to start some kind of processors war

Peace

The tempurature is why my laptop is named 'toaster'...And since it's a laptop, you know what it's toasting......

I have an acer 3613 laptop with a Pentium M 1.5 ghz and it runs at around 48C up to 55C at it's hotest, even with processor throttling enabled. This has been my experience with all Pentium Ms (when in a laptop at least), and I think you'll find that they are desinged to handle temps in excess of the normals that we would see on a desktop.

what kernel is everyone on? I never really used 2.4 on this laptop. I installed slack then went straight to 2.6

slightcrazed · 03-20-2006, 03:02 PM

2.6.14.13

processor throttling enabled using 'conservative' mode most of the time.

cwwilson721 · 03-20-2006, 03:50 PM

Custom compiled 2.6.16

bird603568 · 03-20-2006, 04:01 PM

thats odd, i wounder why are getting different temps
