In the case of the lm3875, I use silicon paste but if you use thermal pads (to isolate the chip from the h/s) you don't really need any paste.
i'm using pads from old chips and sinks in the scrap bin.
if you're using a small sink or a really hot chip, perhaps paste is better? i know the overclocker crowd found pads weren't near as good as paste, but they're dealing with very high temperatures in cramped conditions. not quite the same thing.

I have used Silpads, which require no headsink compound, and also mica and aluminum oxide insulators, which require heatsink compound. I just picked up some silicon heatsink compound from digikey, and works great, but makes a mess if you apply too much. When I use it, it always ends up getting everywhere...

Re the heatsink paste: If you want the best, you should probably get Arctic Silver Ceramique. That is what I use in critical places. I am sure it is overprized etc. but hey if you don't need much - go for it!

i use some greasy silver stuff from a surplus store. works perfectly. It's called "Heatsinks Compunds". 😉
Without an 'o' so that's probably why it's in a surplus store. I think i bought it for one euro (not sure though).
Ha, just found the manufacturer. Titan. a small link to this stuff . It acually has silver in it !!
