That depends upon your application. Between the controller's outside and
the base plate, I agree with you.
However, I'm using this between the MOSFETS and DIODES and the interior
heatsync, which also doubles as one of the power rails. The circuit is
designed such that the mosfets and diode cases must be electrically
connected to the heatsync. (The heatsync is electrically isolated from
the case by a SiPad.)
So I'm looking specifically for something that will conduct electricity
AND heat. (The MOSFET's and DIODES are connected via a screw, which will
conduct electricity, but I figure the lower the resistance the better.)
The carbon grease is electrically and thermally conductive, but it
appears to be designed for switch contacts more than simiconductor
heatsync applications, and is probably not as conductive as a silver
grease, so I'm still poking around looking at what my options are to
purchase.

Hi folks
Heat sink grease should be NON conductive electrically but thermally conductive
white grease. You can also use thermosil less thermally conductive but less
messy or Kapton.
