Hi Friends,

I have bought new R51(1.7Mhz, ATI9000) and now have a question.
I have checked CPU temperature with Mobile Meter.

High Performance - CPU idle, 64C, no fan working.
High Performance - CPU 100%, 69-73C, fan start working at 70C.
High Performance - CPU go to idle, temp go down and at 40-45C fans stops. Temp go up to 64C.

Could you please decribe how you laptop work?

Thanks,
Vova

I will happy if you help me.

R51 with 1.7Mhz, 60Gb, ATI9000, AC adapter + Maximum performance

The behaviour of R51 is following:
1. Switch on power - fan start normal-max-turn off in POST moment
2. Windows starting - all okey. Fun does work.
3. 0% CPU load - temperature a rise to 70C.
4. At 70C starting of FAN (low) (0% of CPU load - 1.7Ghz)
5. Temperature go down to 50C. In 1 minute fan is off at all.
6. 0% CPU load - temperature a rise. Go to step 3.

Fan turn on periodically when CPU about 70C to climb down temp to 50C.

I give 100% CPU load
1. Temperature a rise fast to 74C. Fan starting at low-normal mode.
2. Temperature stable to 70-73C (I check 20 minutes).
3. Give 0% CPU load -> temperature go down to 50C and fan working a long (5-6 minutes) then off.
4. 0% CPU load - temperature a rise to 70C.

When I ran GTA3 fan start work faster(but not max). Regarding MobileMeter CPU temp about 67C.

What you can tell me about behaviour? Is it correct to periodically turn on FAN (every 1 minute) from AC?

Your idle temperature seem rather high. 70 C!!!!
do you have set it to adaptive mode?
even if it was in high performance more it seem to be pretty high.

YOur fan shold be working well before it reaches 60 C and anything above that it should work at full blast.

My T42 idles at 42 C and at full load it may go up to approx. 65 C but never remember go up to 70C.

No. On full performance. The temperature always go up. And at 70C fan turn on.
In idel mode of adaptie performance in case of fan off temp about 52C.

If Fun working constantly in slow mode temp in full performance go down to 48-50, at adaprive - 38C.

What is your laptop behaviour?

That seem to be normal. That is pretty much what I see in my notebook.

my R51 has the 1.5MHz and Radoen 9000,
with a Long M10 Fan fitted, and all power saving on (CPU adaptive).

just now, it did lots of 100% cpu work, 7-zipping, lots of hdd activity
and burning a dvd, whereby the temprature did not exceed 50°C,
according do MobileMeter. Ambient temp is 19°C. Even so it feels
already uncomfortably warm on the legs.
idle it has about 40°C.

Check if there are any background prozesses running, e.g. indexing service, and switch on all powersavings you can find.

Maybe let IBM Support know about these temperatures.

Besides:
70C seems too hot for me... a good heating brick for the arctic winter.
I mean we are discussing portable computers with Mobile CPUs, aren't we,
and not HiPerf Gaming machines.
At my work place I observe my colleagues using calcualtion
intensive programs (FEM, Autocad, numeric simulations) on other brand
of notebooks(various Toshibas and HP's). There are 2 or 3 calculations running on one machine for hours and on top of that normal office work is done (email, word). Really cruel stuff.
I've never heard one of them complaining that one notebook would overheat or even that it would get uncomfortably hot.

To lophiomys:

Can you try run in Calc "9999999999!"
and check temperature in MobileMeter.
And describe fan and temperature behaviour.

If possible send me ScreenShot.
I also do that.

Thanks

vovan,
hope I did comply correctly to your mesurement procedure.

anyway,
here's my R51's temperature log:

Lophiomy:

Today I make my temperature graph.
It is Full CPU Performance (1700Mhz) with 0% load.

I'm glad I found this webpage and this post. This is exactly what I was looking for.

I think I have the same model as vovan, 60Gb, R51 1.7Mhz and the same behavior.

Only problem is I can't hear the fan speeding up... its always on and quite but at

100% cpu usage, temperature rise up to 78 C !!!! (At this point I stopped the cpuburn program and started violently waving my hands around the ventilation window)

IDLE temperature in 1.7Mhz is 57 C

I've seen the same behaviour in Linux and was worried... Is this normal then???

are there anyother users.

And for those windows users... how do you set up your power performance (freq scaling)???

riczan · #11 Post by **riczan** » Tue Jun 14, 2005 8:31 pm

Further tests (running cpuburn) to make cpu 100% revealed that temperature rises and keeps rising and I never hear a change in speed of the fan. Maximum temperature I attempted was 82 C!!!!

How are you testing??? Maybe if you are using graphic related applications for your testing you are listening the graphics fan...

anyway... I'm using windows and everithing is supposed to work, right???

So far I have never seen the temperature drop because of a fan operating... Only if I stop the testing the temperature drops.

How do you make it work in adaptive mode??? do you set up that in the BIOS? maybe I need to try that too.

Riczan:
Mostly fan start work fast only when havy 3d application works.

I have made simple test by type in windows calculator 999999999!

and get provided graph.

Some time my CPU also has 82C but as for me it's not very critical. CPU has protection.

I have playing in GTA5 (SanAndreas) and very hot air blow out from vent. window but CPU temp still on 70C. I think GPU is a result of high temp and high speed fan.

thanks Vovan

In linux I like to use cpu freq 1200 MHz for heavy use, which gives me twice the speed for normal use and temperature only rises up to 58 deg... I read somewhere that ibm support said that processor shouldn't work at temperatures over 70 deg.

In windows...

Does anybody know how to have variable frequencies? e.g. Have it running at 600 MHz and only change to 1200 MHz when running demanding applications?

Rightnow, when idle, temperature is already 58 deg!!! that's because is running at 1700 MHz... I don't like that.

Yup, that is about right. My company has about 10 of them, and they all run hot - in the 50 - 70 C range. The IT department doesn't seem too worried about it, so I don't...

Wow...I've been reading about temperatures for the Pentium-M cpu's in this thread and other threads in the T-series forum and I'm shocked by some of the high temps - 88c, etc. Within thermal spec, but *[censored]* that is hot.

I'm researching a pentium-m for my uncle and he plans to use it a lot sitting in a recliner. I have no problems with my current thinkpad doing that (I've been using the machine an hour or so for normal tasks and my cpu is at 37c and been steady there for at least 15 minutes - not a Pentium-M).

Do you have problems using your thinkpads on your lap for extended periods at these temps (there was one reference to uncomfortable above but I'm curious for some more opinions). Thanks!

That's about right...
