Since liquid metal paste, as the name suggests, is relatively liquid, the Thermal Grizzly applicators are the ideal aid for spreading the paste. With this pack you get three black Thermal Grizzly applicators , which allow the application or even distribution of a liquid metal thermal paste. However, The liquid metal thermal paste must not be used with aluminum contact surfaces and never comes into contact with electrically conductive components.CPU coolers with aluminum coldplate can not be used, instead the materials copper, nickel or silver are recommended. Especially with Intel Haswell, Devil\'s Canyon and Broadwell processors care must be taken that the liquid metal paste does not come into contact with the numerous technical components under or next to the heat spreader.Also with Skylake and / or Kaby Lake CPUs there are some contact points, which should be covered with tape for security, if necessary, and even with AMD CPUs appropriate caution is advised.
