Thermal Grizzly he presented PhaseSheet PTMa new phase-change thermal pad that It changes from solid to liquid when it exceeds 45°C. The new pad has many advantages, including the price: the new pad is already available on the official site at the price of approximately 10 euro.
The pad has some advantages over the traditional one KryoSheet of Thermal Grizzly, first among all the non-electrical conductivity. The sheet, in fact, is completely safe for use both between IHS and heat sink of desktop systems and between the die and the heat spreader mobile solutions that do not have an integrated heat spreader. Furthermore, unlike KryoSheet pads, the new PhaseSheet PTM It can be reused without the risk of damaging it.
Another advantage is the drastic reduction of the “Pump-Out“, or that phenomenon which, due to the contraction or expansion of the metal of the IHS and the heatsink, slowly pushes the thermal paste out. This causes a reduction in cooling performance over time..
The pad requires a pressure between 300 and 400 Newton (35.5 kg and 45.7 kg) of pressure to obtain optimal positioning and the lowest possible layer thickness. Furthermore, it takes about ten cycles above 60 °C to stabilize itself by providing the largest possible transfer surface.
Of course, this is a very distant solution from the liquid metalbut undoubtedly safer and simpler to apply and with a significantly reduced risk rate, a great alternative to traditional thermal pastes.
