Do you mean silicone pads ?

There's simply no purpose in using heatsink compound with them. In as
much as it adds something to the thermal path it must increase the
thermal resistance at least by a tiny bit.

Bring back mica and berlyium oxide.

I prefer live heatsinks myself. That helps keep the device die that much cooler.

BeO2 is potentially dangerous (carcinogenic).
