Arctic MX-4 is non-conductive. It's the metal filled thermal pastes that are risky to use. IIRC MX-4 is ceramic based. On Thursday, May 3, 2018, 3:17:05 PM CDT, JJ <jajustin@...> wrote:
I read that silicone is somewhat conductive so you need to be careful with
the transistor. I use arctic silver 5 (which is not silicone based) but you
should be able to use any silicone based compound that is formulated for
heat sinking such as Dow Corning 340 or the equivalent.

? ? I am still working on my 453. The HV transformer is mounted with some
sort of clear grease. I think this is heat sink compound but may just be
silicone insulating grease. What is recommended here?? I am also replacing
Q-930 and wonder what compound is recommended for it.
? ? I have clear silicone grease intended as a HV insulator by GC
chemicals, is it OK for the transformer. I can get regular heat sink
compound locally if necessary.
