aolsuxs, I have the washers installed on my AX-7 and while I run high CPU temps, currently 65C under full load, my system is stable and the washers have not melted one bit.
In my experience, having the fan "blow" works better than having the fan "suck."
As for the 3 prong clip install, follow blades instructions, you'll do just fine.
Don't forget, if at all possible, use AS3 and not any thermal pads as you will see better CPU temps, hope this helps
