The bloke on that 'tutorial' even said if the X method is used, (put an X of the stuff on and then spread it with a spatula) when the surfaces are put together, start at one side and roll it on so as to push out the air.
Well good luck with that one. With all the veins and gubbins, it's nearly impossible to have one side lower than t'other for a smooth rolling action.
much as we were saying:
The thermal paste itself is not as thermally conductive as metal, however, so it is important that not too much is used. If that happens, the thermal paste will behave more like an insulator than a means of improving thermal performance.
Gone to the trouble of making a Plexiglass surface to look through.
