T7400 very high temperatures!!!

[Papis]

I have just bought a laptop with a t7400 and intel 945PM chipset.I downloaded intel's thermal analysis toolkit and when i pushed the cores at full load the core temperatures went as high as 93 Celcium!!!Is this normal?,i have read that the safe working temperature for this model is 100 C,but still 90 c is very high.I know that laptops don't have serious cooling systems but still i wonder whether the laptop i bought is problematic or not (should i return it??)


Any help/info would be greatly appreciated.
Thanks

Oh and the gpu is geforce 7950gtx

It's most likely F that's converted to about 34C, otherwise it's the temperature censer that's reading it wrong, if your laptop actually ran at 100C you would have melted parts. And it would me literally Untouchable from all the heat that would be seeping through.

Battery Life and Heat

The Core 2 Duo T7400 ran extremely hot in the Dell XPS M1710. While idling in Windows, the CPU had a temperature of 67C (152F) which is not normal. Oddly, the laptop didn't feel warm and I couldn't feel warm exhaust. Seeing how proper cooling is critical to the life of a laptop (or any computer for that matter) I wouldn't recommend putting a Core 2 Duo into a XPS M1710 just yet until we get some updates from Dell.

Last I heard, the CPU would shut off at around 80C.

So you people say its something wrong on the cencors reading the temperatures but when idle in windows (the intel thermal analysis tool) shows
CPUO (digital temp C)=31
CPU1 (digital temp C)=31
when i put on both cores the worklevel tou maximum here what is what it shows(after 1min or so):
CPUO (digital temp C)=98
CPU1 (digital temp C)=96
and then in drops at 60 or sth

I also have the ACPI thermal Zone temp sencor usually a liitle higher than the cpu temps and i don't know what that measures.

i am starting to worry...

that's a defective cooling system you got. Well, not defective, but perhaps it was not designed to handle that much heat. I would assume it can happen, when manufacturers hurry to release new laptop models.

Is the CPU throttling at that temperature? TAT will indicate if the processor is throttling.

Also, you have to consider that the 100% workload test in TAT generates power dissipation far hotter than even extremely well-optimized applications like Prime 95. And Prime 95 itself generates power dissipation much higher than nearly all real-world applications. The TAT workload basically is a power virus, designed only to maximize power usage and test cooling systems.

Yes the cpu is throttling when reaching very high temperatures..
Will this laptop cooling plates help?
Does anyone know the "normal" temperatures at full cpu usage?
To tell you the truth,i am a little bit dissapointed.I mean this processor sure is fast,but i can't use the cpu at full load when the temps reach such high values.(i am running CFD codes).Maybe I rushed bying a high end laptop.

HI again,I runned Intel TAT again and i disabled cpu throttling and started the 100% work load test,
CPUO(digital temp) =97c
CPU1(digital temp)= 87c
Acpi termal zone temp=90 C

the thing is that even though the temps are too high(i am running the test for a while now) the notebook works with no problems and i have no stability issues.Maybe i am doing the wrong test
i also run the hmonitor utility which shows
CPU0()=82c
CPU1()=71c
Oh and the intel thermal analysis tool identifies the processor as Pentium M(???)
does anyone know what's going on.I think that with acpi disabled i should have a crash if the cpu temp reached such high values.
Maybe the displayed values are Fahreneit,however the program tells clearly that it's celcium values.
I am tottaly confused
