In simple terms:

Lowers your Heat by ~5*C
Lowers need for fan (with my eeectrl profile, the fan is off most of the time)
Removes Keyboard flexing (and "more responsive")

... here is my "story" and some thoughts? ...

I used TO-3 silicon heatpads for same purpose in my 900.
Something like these: http://parts.digikey.fi/1/1/52772-heatp … 10-05.html
I did try alumium sheet, one I bought was too thick, and I did not want to play whit household foil.
First I tried to find sheet of that silicon material, any of the suppliers around here did not have that in stock. You may find that from your local shop, but is it really needed to cover from side to side? So then I boght six of those TO-3 ones and placed them randomly under my keyboard.
They are 0,24€ per piece in one of the local eletronics shop, so low cost.
Easy to install, just drop them in place, less than one minute.
It did help whit the keyboard flex, do not know about heat, at least my keyboard feels warmer.
I think that these silicon pads are even better solution than solid metal foil, they are flexible.

... logging out ...

you' could do with some thermal paste there to help 'make' the connection between the copper and the ally

Hey I had to try it

Cms, did you give any thought to taping the edges of your mod to make it spill resistant?

Now that you mention it

Its not my idea

The computer already has an aluminum shielding that is both to act as the cooling system and structure for the keyboard to rest on, though unfortunately (as you can see by the keyboard flexing when you press in the center), There is an extreamly small gap between the shielding and keyboard.

Aluminum is probably the 4th best heat conductor (I can think of: 1. Diamond 2.Silver 3.Copper 4. Aluminum)

With Copper, heat will better transfer from the motherboard to the top of the shielding, It will disperse amongst the entirety of the shielding rather than just one area.

Along with the dispersion, there will be more heat conductivity between the sheilding and the keyboard, The holes in the keyboard allow for fast passive cooling. The keyboard is metal too, thus, your not covering the holes, your providing more cooling surface area, thus, even more passive cooling

I can tell you that there is defiantly more heat coming from the keyboard now

My fan is off most of the time now. (I run 43-50*C now, Used to run 50-55*C) I am very pleased.


The Original Aluminum shielding prevents anything from touching the motherboard, there is no risk of the copper getting into anything


How hot does your netbook get, try using HWmonitor

more metal = more thermal conductivity

If you put thermal tape and sheeting, I would expect improved results

@Cms
Hmm, seems resonable enough .
How about cutting holes in aluminum shilelding where chipset and CPU are and sticky (with a  thermal tape of course) a bit of copper to the foli in those areas so that it will touch the chipset and CPU after covering the aluminum for even better result.
It would then work exacly as radiator with thermal paste (those pieces could also be covered with this).

I'm also concerned about battery cable. Why some1 just didn't connect it directly without such a long cable (why not to put right into the battery connector). It would also improve EeePC cooling.

IMHO this scale is to small for this rule to apply.
If we'd be talking about 20 cm of cable then I'd agree with You, but here's only about 5-6cm max.
Besides isn't it much easier to just adapt a proper battery instead of a wire? (wire costs while You still need to buy the battery)

Anyway if You'd open Your case someday for more mods and having a voltage measure tool under Your hand, would You please write down the voltage and post the result?

Hi,

I must admit, this mod seems **** at first, but the testimonials makes me want to try it.
I mean exclusively for the temperature benefit.

I don't find that my Eee pc keyboard is laggy anyhow.

Has someone tried it on 1000HE?

Cms, what is your Eee PC model?

In addition, I must precise that the air gap that we're looking to fill acts as a thermal insulator (not good here).
Styrofoam which is largely used for insulation is made of millions of tiny air gaps.

Thanks

Man, of course not!

I was talking in the idea of how the air gap is bad and why we're trying to eliminate it here.

Hey I just had an idea, some were saying that the foil was keeping the heat inside.
Well the Keyboard holes aren't there for nothing for sure.

With the foil we want to fill that gap in order to promote heat conductivity.

Well, who said we couldn't make holes in the foil so we'll have both max heat conductivity and max ventilation???

technicaly the air under the keyboard is supposed to be "moving" because of the fan, but from the temperature ratings, allocating more air flow through the motherboard while the keyboard uses conductive cooling is a more efficient design smile

Thoughts: Ok let's say that without the foil the keyboard is sitting on air flow. Heat conduction from a metal to an air flow is less than direct metal to metal conduction.

Thanks
