Question about ArcticSilver Thermal Adhesive

[magoo]

I have a couple of copper MosFet sinks I'd like to use.
Unfortunately the push pins are exactly opposite the mounting holes on the MB.

Could I mount the sinks to the MosFets using ArcticSilver thermal adhesive?

I realize it will be permanent, which is fine.

I'm concerned on fubar-ing the function of the MosFet.

Thanks in advance.

You can use thermal tape... But yes, if you want to permanently attach the sinks then go ahead and use the thermal epoxy.

What concerns me is this......if I spread a thin layer of the thermal epoxy over the bottom of the heatsink, when it (the glue) contacts the MosFets, will there be any electrical conductivity?

I have used thermal adhesive on ram before, no problem.....but never on a string of little bitty ICs like MosFets......I'm afraid I might fubar the whole thing.

yes the arctic silver adhesive is conductive

The ICs don't have a metal top, right? I haven't seen those sorts on motherboards to my memory...

If you are concerned, I believe they have Arctic Alumina Adhesive as well. I remember an old trick was actually to only use the epoxy on the corners, that way it was still removable and a better material can be used in the center.

For the record, Arctic silver , either epoxy or paste, is not conductive under normal circumstances. It does have some capacitance though which has the potential to cause issues if it gets on certain sensitive signal traces. On mosfets it shouldn't be a problem at all. If you're really worried about it just use Arctic Alumina thermal adhesive instead.
