Dear  Chris C.
  There is no such compound, as per my knoledge, there are only two more
ways to increase heat transfer.(1) increase the radiation area by
extension in the sink (2) use fan to increase the air flow. there are no
of small fans avialable such as fans for cooling CPU of desk top
conputers and fans for power supply of computer.
