Default SSE - Thermal paste for CCS to heat shield??

I'm putting together a SSE board and was looking at the heat sinks for the CCS. Are you guys using thermal paste or anything for these. There's nothing in the build directions stating anything on it.

Heat sinks should be used with a thermal interface, such as a thin layer of thermal paste
under the right compression force. Otherwise, the thermal resistance of the sink to device case
increases, causing the junction temperature of the device to increase.

+1 for the thermal goop. It actually makes a big difference. I use Wakefield 120 thermal grease. The "126" model would work as well. The difference is that the "126" is more tolerant to solvents used for PCB cleaning.

A less messy option is to use one of the silicone pads, such as Bergquist SilPad. They're pretty inexpensive and easy to work with.
