Cooling mod for a Dell X1

post #1 of 4
Thread Starter 
I figured if anybody knows, it's probably you guys.

So I have this fanless notebook, the Dell X1. And it overheats like a ***** due to the heatsink actually being a 0.6mm sheet of aluminium with a puny excuse for a heatpipe bodged onto it by the trained monkeys at Dell.





The stock heatsink has a dissipation surface of 50cm^3 or thereabouts, NOT taking into account the heatpipe.

There is enough room in there for a 100mm*70mm*2.5mm copper block, which would have a dissipation surface area of 175cm^3 or thereabouts, not to mention better conductivity.

Reckon I should give this a go? I'm thinking epoxy it to the CPU/GPU since obviously there won't be any way of securing it through screw holes.

The CPU is a Pentium M 733 ULV 1.1GHz which puts out 6W maximum, and the GPU is a lowly GMA 900.

Cheers

Epoxy won't work, it's an insulator.

Adding to the surface area of the heat pipe would be more efficient.
The heat sink just picks up the heat, the heat pipe does the dissipation.

I'm assuming he meant thermal adhesive, like ceramique.

^That I did.

The thing is, the heatpipe is pretty thick and is the reason why the rest of the "heatsink" is only 0.6mm thin. Surely if the entire thing was a big copper block of 4x the thicknessit would function better, especially given how small the heatpipe is?

Hell, it's only a 6W CPU and a ~3W GPU.
