Cooling pads or not?

[cluca_alex]

Can someone tell me if the pads on top of the heatsink of the T43 are for cooling or for isolation? I would like to know if they act as heat conductors from the heatsink to the keyboard metal, or not.

This is what I am refering to:

The grey pads...

Thank you!

Heat is designed to be blown out the side vents and not to be conducted into the keyboard. So my take is that they are for isolation purposes. If heat was conducted into the keyboard then you would get premature keyboard failure.

My guess is that it partially allows heat to transfer to the keyboard which is a win-win for both preventing the keyboard from failing and bringing down the temperature by just a bit. Also I forgot where but I remembered seeing a feature called keyboard cooling that brings more air flow when typing. So basically when you press down a key, the rubber cap sinks down and brings tiny, tiny airflow to the main chassis and if you type constantly enough (and at that T4x's keyboards are still pretty comfortable, especially compared to today's Dell, Lenovo, Asus and MacBook keyboards even though not the most comfortable like A3x and 600), there will be some airflow blowing onto the heatsink part including that nylon rubber like pad on the top of the heatsink.
