That's not for the faint of heart

Just get some Keratherm sheets and be done.

I looked up the Kerafol. Mine looks very much like the grey Kerafol 86/600 Wärmeleitfoil 0.5mm 6 W/mK It says the layer has Glasfasergewebe, and mine also has the glas fiber inside.

Think I'll trust the foil then that was provided with my devices then.

Do I need extra paste? Such as Kerafol KERATHERM KP97 Koelpasta?
The devices are not super flat on the heatsink, an opening on some sides is easily 50 microns. That is, I can rock it a bit. But the "Kerafol" should damp that out.

Yes, in this respect it is much more forgiving against imperfections in both surfaces: the sink and the device.

The mechanical damping is certainly interesting. I wish someone would share sonic impressions of various sink interface materials.
