Arctic Silver Adhesive used on PWM Mosfets Safe?

I have the Arctic Silver Adhesive located here http://www.arcticsilver.com/arctic_s...l_adhesive.htm

It seems this is the stuff to use but I need someone to agree before I do it. I am replacing the PWM on my IP35-E with some thermalright mosfet coolers.They dont clip on so I am sticking them forever.

Well, I will go out on a limb and tell you that you will be safe with that as long as its going to be forever. NOT REMOVABLE!
Just don't get any on the solder connections or adjoining "shiney things."

Just be clean and apply small amounts and you should be golden. Shouldn't take but just a 'lil here and there.

Arctic Silver adhesive is capacitive, and slight conductive. It will cause problems if you bridge contacts with it.

I would not recommend using it on fets unless you are extremely careful.

Personaly, I recommend saving the arctic silver adhesive for applications where shorting something is unlikly to be a problem. Get some Arctic Alumina Adhesive for the fets. It's not conductive or capacitive, and I've been very messy with it without issue.
personly i wouldnt suggest Adhesive on most boards. what happeneds when it dies and you cant rma it
I would also not use the silver based stuff. it does conduct and it gets everywhere.

Are there no holes around the area for fixing?
I emailed arctic silver and they said it is not ok to use this kind that I should use the alumina thermal adhesive since thsi stuff is slightly adhesive. i am doing this on an old IP35-E board that is not RMA'able so it dosent matter and It will have to drop temps by 20 degrees I bet as it runs hot.

So the official answer is no dont use the regular arctic silver adhesive on mosfets!! use the arctic sivler alumina adhesive instead! thanks everyone.
