Thermal Grizzly PhaseSheet PTM Thermal Pad 50x40mm
The phase change material used in the PhaseSheet PTM is solid at room temperature. The material only starts to liquefy at temperatures above 45 degrees Celsius. For optimal distribution of the liquid PhaseSheet PTM and thus the thinnest possible layer, a high contact force of around 300-400N is required. PhaseSheet PTM has very low viscosity in its liquid state and contracts again when reverting to a solid, mitigating the pump-out effect.
The pump-out effect is especially noticeable when a copper cooler is paired with a graphics chip, as silicon and copper expand to different extents when heated. Under load, the heat spreader and base plate may deform (concave or convex) and return to their original shape when cooled. This causes thermal paste to be slowly squeezed out, for example between the heat spreader and the CPU cooler’s base plate.
PhaseSheet PTM is more durable than conventional thermal pastes, though not as long-lasting as, for example, KryoSheet, which is virtually maintenance-free. The maximum thermal conductivity of PhaseSheet PTM is achieved and stabilized after approximately ten thermal cycles at 60 degrees Celsius each.
