Temperature check on TP 600E

Hello,

after upgrading the CPU, I want to check the temperature. I am running mobile meter. But I have no instruction. I see 4 temperatures, but which is which? I assume the top is CPU. But what are the other 3 temperatures?

Thanks!

MobileMeter is a system monitoring utility designed for laptop PCs running under the Windows environment. It can show the following information.

* CPU clock
* CPU temperature
* Battery charge/discharge rate
* HDD temperature

Desktop PCs are usually designed to allow the OS to directly read the sensor values, but this is not true in most laptop PCs. Mobilemeter may be able to read the temperature even in such laptop PCs.

I read the instruction, but there is no answer to my question. Mobilemeter shows me 4 ACPI thermal zones. I assume the top is CPU. But which are the other 3 temperatures? (e.g. chipset or graphic core).

I would recommed NHC. www.pbus-167.com

You're only going to be able to monitor the CPU temp/frequency and HD temp if your HD supports it. It's an old piece of equipment.

But strange: The second and third temperature are not constant. Stress test with windows calculator gives:
CPU temp: 81°C
Temp2: 39°C
Temp3: 34°C
Temp4: constant 27°C

CPU temp: 81°C

Thats quite high, isn't it? The hottest I've 'noticed' on any of my LT's is the low 60's.

Just a guess but maybe the 81 is an limit? A trigger for an alarm ? And one of the 30's is the actual temp reading..

The 81°C is the real CPU temperature. Normally it is ca. 40°C. But when I calculate n! then it rises up to 81°C. What can I do for better cooling?

Since you did a CPU mod take it back apart and put alittle Arctic Slver between the heat sink and CPU. That should help quite abit. If it's still running hot look into getting another heatsink/fan assem.

Seriously? Either you have a nice layer of arctic 5, or you don't push them to the limit! I had an R40 that would see 70-75C when streaming full screen video, a 600E that would hit mid 60's, a now the T20 hits upper 70's and t23 up to 70. They'll be taken apart soon for some thermal application.

I should have been clearer, by LT's I meant the 7 or so 600's I have lying around now...So I was mostly talking about my 600 series machines. I would expect R40's and T2x' to run hotter(but 81c is high for them too) then 600's.. And yes most of my 600's are rebuilt so I have added a layer of Arctic Silver to them..

81C seems high for a 600e, even an upgraded one..

Thank you for your advise! I looked for Artic Silver. There are different versions and it have two components. Can you give a short application instruction?

Take the heaksink off.. Use your finger and spread a VERY light coating of Arctic Silver in the top of the CPU. Put the sink back on and your good to go..

I think it depend's on each system. My systems (T20, 770X) sometimes go close to 90degs but so far working just fine.

The 81°C is the real CPU temperature. Normally it is ca. 40°C. But when I calculate n! then it rises up to 81°C. What can I do for better cooling?

While it is a good thing to try to cool further down the CPU, I personally think you don't have to worry too much about it since 1) the mobile pentium III are designed to survive up to 101deg of maximum juncition temperature, 2) the ACPI will slow down the CPU when the temperature reaches at 94deg and 3) at least my systems usually go beyond 80deg under heavy load but works just fine.

So what I want to say is, I also encourage you to cool down the CPU as much as you can, but do not worry so much even if you don't see much difference before and after your effort for cooling down.

2) the ACPI will slow down the CPU when the temperature reaches at 94deg

Is it possible to slow down the CPU manually? Is there a software which manage this? I ask, because it would be interesting to slow down the CPU to have more battery time.

My 600X with a 850 PIII is now at this moment at 58C browsing the internet and using microsoft outlook and is running at 850MHZ.

Yeah, the 2 600x's(650and 500mhz) I monitor seldom hit 60C and my T23 gets to about 62-65C,tops.. I'm sure any of these LT's can handle 80-90C, but [censored] sitting on your lap must feel, well HOT..

This works only on a speedstep machine. Or did this also work on a TP 600E? Can I slown down the CPU manually to have more battery time?

Hi Harald612,

As far as I have investigated, if the CPU is SpeedStep enabled, the clock frequency will be slowed down when the temperature goes above a certain threshold (in my system, PIII's clock changed 700MHz->300MHz at 94deg). If the CPU is not SS enabled, the system shuts down when the temp goes too high. The mobo's SS compatibility doesn't matter.

Can I slown down the CPU manually to have more battery time?

I don't know how to do this. I personally suspect there is no "official" way of doing this.
If someone out there knows how to change the frequency, I also want to hear about it.

I just finished upgrading my 600E from a PII 400mhz to a PIII 500mhz CPU. I am currently burning in the system to insure that everything is working properly. Under high loads the CPU temp ranges from 68C-77C.

I also noticed that the heatsink for the 600E uses a thermal pad. I thought about removing it and using some artic silver but, without the thermal pad there is a significant gap between the heatsink and the heat spreader on top of the CPU. It looks like the posts that are used to attach the heatsink to the heat spreader do not allow the heatsink to sit flush on top of the heat spreader.

From what I understand, you are not supposed to use a thermal compounds like artic silver in conjunction with a thermal pad.

Is this correct?
Is there a way to get the heatsink to sit flush with the heat spreader?
