Hey,

I'm in the market for a new laptop, and one of my main requirements is
that the touchpad and keyboard remain cool to the touch.

I work on my laptop, and my current one just gets too hot during the
day.

Unfortunately searching for "Cool laptop" results in lots of trendy
gizmos and little discussion of which models are powerful enough for
work but also comfortable to work on 10-12 hours day.

I'd prefer to get a 17" widescreen with 2GB RAM. I imagine any of the
dual-core machines will be faster than my current Pentium M, but can any
machine that robust keep its temperature down?

Are there certain brands that pay greater attention to these issues than
others?

Thanks.

If the temperature is all that matters, you can find one with a via c7
or amd geode chip. The performance will suck, though.

There is also a correlation between lower clock speed and lower
temperature. But that is not always true.

You can look up the specs for various processors at:

Amd doesn't seem to have an eqivelent tool.

Temperature is a key factor, but not the only one. And mostly I'm
concerned about the heating up of the keyboard, touchpad and surrounding
areas where my hands might rest.

I think there's more to it than just processor temp: how well does the
case/cooling system (if any) insulate the user from hot palm?

Not real good data on that, but if you have physical access to one
while shopping, you can look for a model that has the CPU and cooler
on the underside of the laptop. (In such case it would be under a
panel, that you could spot). But the majority of laptops by far have
the cpu under the keyboard. and sometimes even use the metal under the
keyboard as a supplemental heat sink. (if not for the processor, then
sometimes for video chip)

You'll never find that kind of data.

Instead, look for laptops with very long battery life. A battery only
holds so much energy, so if it runs for a long time, it must not
maintain the laptop at a high temperature.

If you want to get fancy, take the ratio of battery life to battery
capacity.

A good bet is to get laptops that offer the option to be put into a docking
station - which allow to close the display when using an external display.
The thermal design of such laptops does not rely as much on cooling via the
palm/keyboard area. Typically you get those with the business series of the
main brands - Lenovo Thinkpads, HP nc/nx, Toshiba Tecra.
Apart from that I would avoid laptops with a dedicated gpu for 3D-graphics.
Also harddrives with 7200 rpm should be avoided.
The power consumption of most processors is listed on this website -
although with mobile processors it's alway a bit difficult to give one
value due to the power saving modes such as speedstep or Cool'n'quiet:

Talking about energy saving modes - it's best to avoid the cheapest
processor series such as AMD Sempron or Intel Celeron-M, as these models
lack this feature. Also maybe the fastest processor available is not
required for your work - and a slower model would be sufficient and a bit
cooler in average. Plus you save some bucks :-)

Ironically, you may find that a recent laptop is cooler than older ones.

I have an old Dell Inspiron 3800 with a Pentium 3-600 CPU. It has a
heat pipe that carries CPU heat to a heat sink and fan in the rear
corner of the case, but there's sufficiently little heat generated that
the fan never runs unless you're doing something very CPU-intensive for
a long time. There's no other case ventilation, and the fan only cools
the heatsink when it does run, so over a period of hours heat from the
motherboard, disk, and the CPU get the whole thing pretty warm.

I also have a year-old Gateway laptop with a dual-core Turion processor.
It has a (much larger) fan that draws air in several sets of slots in
the underside of the machine and dumps it out a vent in the side. It
seems to always run at low speed, switching to high speed when the CPU
is busy. This draws some air through the unit all the time, providing
some cooling for everything. And the keyboard/trackpad area stays
cooler.

If you want to maintain the coolness of the laptop (or desktop
replacement system )surface for several hours you should use a
cooling pad. It tends to blow away the accumulated heat......
Its difficult to find a 17 inch laptop that can remain cool for 10-12
hours of continuous use...Even with these core2 duo equipped units
the( surface near the keyboard ) still become warm after several hours
of use.

How come...?
The question is about huge powerful laptops that remains cool for
several hours of use( vicinity of 10 hours) ......
Is difficult to find one in the market even with the recent models
Lets get practical..in my experience ..huge laptops are somewhat
different animal if compared to the normal ones with regard to comfort
in use after a prolonged period of time daily....
I still have to find a 17 inch laptops with powerful processors, etc
to remain comfortable to use for that duration without a cooling pad
underneath..
BTW just a few weks ago a former coworker of mine who was
transferred to another branch of the company I am connected with
complained that his newly purchased core 2 duo equipped 17 inch
desktop replacement system is also hot and uncomfortable to use after
several hours.
I told him the same thing ....place a cooling pad underneath and
it .....after a few days he called me back and sure is..
It solved the problem......

If you don't have practical experience on using these
behemoths ...then just be quite...okay..?

Hey, I started the thread, and it seems on topic to me.

with my first laptop, a Vaio which got very hot on the underside, I did
use a cooling pad. Most of the pads I've seen are pretty crummy,
however: noisy and don't last very long.

I'm not against using a pad; I was just wondering if any brand of laptop
had a reputation for better heat management than the others.

Are Core Duo processors supposedly a bit cooler than P4s?

Crummy and Noisy cooling pads....? LOL mine runs silently and
efficiently and its already 3 years old.
I have seen desktop replacement systems (17 inch models) used by
friends, colleagues, and relatives but when I asked them the nature of
the heat management the units still get warm after several
hours....Even the Core 2 duo systems.
I have asked people who have used other larger notebooks to have a
feel of mine and they says that this big VAIO runs cooler than their
units....( even if the cooling pad is removed) .....
Core2 duo are claimed to have better heat management but for larger
units it seems to be the same with Pentium M equipped version...these
wereconfirmed by users I communicated with....
Inspite of that
