    Very good paste keeps my cpu and gpu nice and crispy cool. Kind of annoying to apply due to its viscosity but the applicator makes it pretty easy to do.

    Was a little skeptical considering the cost of the thermal past but it worked well. Not as easy to manipulate as other pastes I have used but does come with some stencils to help not overdo it with the paste application.
