Good day, I'm still working on mounting my ZEROtherm NV120. I got stuck installing the heatsink because I needed a long phillips screw driver to turn the mounting screws into the back plate. I need to go buy a long shank screw driver. This delay gave me the opportunity to think about the installation a bit.... The question that jumped into my mind was this. To what torgue value do I tighten the screws? I don't want to crush the chip or stress the board any more than necessary but want to make sure I get a good contact betweent he sink and the chip. Anybody have a number? Thanks, Phil ps, the heatsink manual gives no indication of how tight.
