Applying the ARCTIC MX-5 is the same as any other thermal paste. Simply unscrew the cap at one end of the syringe and apply pressure to the plunger to get the content out of the barrel. The MX-5 paste itself is blue in color. I am not sure if this was intentional or not, but it is an appropriate color for the brand. The paste is carbon microparticle-based with no electrically conductive nor capacitive properties.
