Innovation in heat-sink design?

20 years ago, if you opened up a consumer-level desktop computer its heatsink would be a "metal grill" type device place on top of the CPU.

20 years later, if you open up a consumer-level desktop computer, its heatsink will most likely still be a "metal grill" (albeit smaller) type device on top of the CPU.

How come with millions being spent on microproecssor R+D, trying to reduce heat emissions, heatsink design seems not to have experienced any radical innovation. For a component which plays such a crucial role, I am surprised by this. Can anyone help explain it?
