Modding a laptop's heatsink for better performance - Hacking/DIY at its best

Because you're blocking airflow in an already confined space, thus helping kill the machine?

hmmm, people with an EEE PC 701 4G sometimes would add shims to the single massive aluminum heatsink under the keyboard, to help with heat and prevent (as you mention) flexing keyboards.
I'd be interested to see what you could do with copper mesh and copper sheet - that'd avoid the need for drilling. (I mean this politely, but your drilling was AWFUL!!)
I know the drilling was awful :-) - I used an 800 Watts power drill with 1.6mm drill bits (that thing fits 14mm bits!), didn't have anything else. In the end it works fine.
A sheet and a mesh is a good idea, but it would take too much work and the heat transfer would be impacted - I specifically drilled the holes so that the copper sheet is cooled by incoming air, therefore acting like an additional (large) fin for the heatsink.
