do you think this is possible?

I was thinking, for the purposes of improved cooling, do you think there is
any sort of shop that could take the plastic doors that cover the memory and
the hard drive on the bottom of my laptop and make exact duplicates out of
copper? Do you think it would cost a bundle to just have one of each made,
or would it be fairly affordable? Aluminum wouldn't be as good a material to
use, right?

The problem with that is I would lose my warranty. If I made copper covers,
if I needed any warranty work I could just slap back on the original covers.

OK, cruse eBay for a second cover...

Aluminium is probably fine, as long as you cover it with a plastic layer
to avoid shorting things.

Why do you want to cool the RAM?
If you put an aluminium or copper plate on it, and maybe a conformal pad
in between that and the RAM, you may lower your RAM chip temperature.
However, you probably will cause the RAM door to get a bit hotter.

get a copper sheet at a hardware store. it will cut with scissors.
use a small hammer and a block of wood or a stone to form it. use a
drill if you need holes in the copper.

search computer stores online for heat transfer materials. use heat
transfer adhesive to attach a pad or sheet of heat transfer material
to the copper.

copper will oxidize. use clear lacquer to seal it. this may obviate
the "conformal pad" because sufficient coats of lacquer will render
the copper non-conductive. seek a heat transfer type of lacquer.

voila.

The rest of the info (and this info) was very helpful. My only question now
is will it be easy enough to shape that I'll be able to shape the two little
tabe (like on the battery cover of a TV remote) that go into one end of the
notebook? Also, the current cover has aluminum (it's like 1 sheet of
aluminum that was cut so that it has many fins) around the outside edge.
What is this for and do I need to duplicate it?
Thanks,
Richard

I think I would waste less battery power on the fans if the ram were cooler.

I'm late to this thread, so maybe this has been suggested: have you
thought of drilling small holes in the existing cover, maybe a
half-centimeter apart in a grid pattern? That should aid cooling,
especially if your laptop has feet in the base to let air circulate.

But wouldn't copper provide even better cooling (or copper with holes in
it)?

Hm, sounds like a G4 titanium notebook!

really, the problem is that w/o solid contact between the source of heat
and the copper plates you'll replace the plastic parts with, you won't
get a very good conduction of heat. And, even if you've got a solid
copper unit, you still have to problem of dumping that heat into air.
If the surface is still the same as before, it won't dump that much
faster and you'll still have a toasty hot laptop (except coppery
colored) on your lap.

Think of it like putting a 100 watt light bulb inside a plastic pot vs.
a copper pot that's sitting on your lap. They'll both get hot and
they'll both not dump heat fast enough to matter.

You'll have to figure out a better way to ventillate the laptop to dump
heat any faster - more heatsink fins, more fans, water cooling (but
where to put the refrigerator/radiator part?), etc.

almost all notebooks today run in the 35-45 C range, so getting that
temp. down is going to be tough with just copper plates.
