Ridiculously hot Core Duo?

[AmberClad]

Do I have a mislabeled Pentium 4 M on my hands here ? I'm using a Dell laptop with a Core Duo T2600. The thing idles around 53C according to CoreTemp. I'd have a hard time getting the load temps of a C2D up that high, even if I tried. When I compile code or run Orthos on this particular laptop, the temps can approach 70C. No stability issues (yet).

Is it just me, or does this seem a bit abnormal? Possibly a faulty temperature sensor?

The laptop really doesn't feel all that hot, maybe somewhat warm. Certainly doesn't feel nearly as scalding hot as my old P4 Inspiron.

probably a crappy cooling solution from dell

Definitely a possibility. The fan (if there is one in there) is inaudible to me, which is a little worrisome.

Does CPU-Z offer any insight into this? VIA Spec wise.

Funny you should mention that. I actually did have CPU-Z open recently while I was trying two different power bricks with the laptop. The first brick was a 65W one...not sure which laptop it originally came from, but it may not have been this one. The second power brick was a higher wattage one that did come with the laptop.

It seemed like that lower wattage brick caused an underclock (the Speedstep/multiplier seemed to be stuck at lower than normal). But not really a noticeably lower temp than usual.

So I guess it really could just be an abysmal cooling setup design .

Perfectly normal temperatures for a laptop.

My 2 GHz Sempron idles at ~50C (Vista HP - was a bit cooler running XP).

Laptop CPU's have the idle and maximum temperatures much higher than desktop CPU's.

Just make sure that you are using a laptop cooler to keep it well ventilated.

Do those laptop cooling pads actually work? You wouldn't think that the plastic case on a typical laptop works too well for transferring heat.

*wonders why laptops aren't made out of anodized aluminum*

Works for me - I use it all the time. This way I can place it on the couch, or... the bed sheets without worrying about blocking the vents.

Aluminum would just get too hot - it really transfers heat well. Too well for a little box filled with hot components and 60C CPU's.

And I guess it's worth a try for 10 bucks AR.

Thermal specification for mobile CPU's is about 20c higher accross the board than their desktop line.

Your particular CPU, all four steppings of it has a thermal specification of 100c at Tjunction. All mobile CPUs when intel refers to thermal specification is Tjunction. Desktop CPU are taken from Tcase.

Anyway, your laptop is perfectly and is designed to take a thermal beating.

Companies run them on the edge to make quieter, smaller laptops. It's also cheaper.

Thanks for the info. That does set my mind at ease a bit. I know I'd be near panic if I saw those types of temps on my desktop C2D, so good to hear that it's not an issue for the mobile Core chips.
