Default help on choosing insulator

Hi all.... I am in the process of finishing a Zen V4.

I got both channels running and have the sinks already, so now, I am trying to figure out the chasis lay out and the best way to mount the transistors, since the way they are now are running a little hot

I am trying to decide between Kapton, Delta Pads or Sil Pads

any coments.

Another question... I know that Kapton and Sil Pads are Greasless... how about Delta pads?

thanks.

Hi,

if you can believe the specs the kapton ones have only 0,07K/W wich makes them the best by far.
Ive used them for my Aleph5 and X without problems. The big advantage is that they already have some grease applied so no messing around with grease all over the place.

I found some specs on kapton and found the thermal resistance to be 0.4 .... Where did you get 0.07 from?
