## Overview

Thermal Grizzly PhaseSheet PTM is a high-performance thermal pad featuring phase change material that liquefies above 45°C for optimal heat transfer. It offers excellent thermal conductivity, is non-electrically conductive for safe use on sensitive electronics, and maintains stable performance after multiple thermal cycles. Designed for CPUs, GPUs, and other electronics, it minimizes pump-out effects and ensures a thin, durable thermal interface.

## Description

The phase-change material on which the PhaseSheet PTM is based is solid at room temperature. The material only begins to liquefy at temperatures above 45 degrees Celsius. A high contact pressure of around 300-400N is required for optimum distribution of the liquid PhaseSheet PTM and thus the lowest possible layer thickness. PhaseSheet PTM has a very low viscosity in its liquid state and contracts again when it changes to a solid material, thus minimizing the pump-out effect. The pump-out effect is particularly pronounced when combining a copper cooler on a graphics chip because silicon and copper have different linear expansion when heated. The temperatures under load cause the heatspreader and the base plate to deform (concave or convex) and return to their original shape (straight) when they cool down. As a result, the thermal paste is slowly pressed out between the heatspreader and the base plate of the CPU cooler, for example. Outstanding thermal conductivity Consistently high performance Very long service life Versatile in application Not electrically conductive Easy to use PhaseSheet PTM is more durable than traditional thermal pastes, but not as durable as KryoSheet, for example, which is virtually maintenance-free. PhaseSheet PTM develops and stabilizes its maximum thermal conductivity after around ten thermal cycles above 60 degrees Celsius. Scope of Delivery 1x PhaseSheet PTM

Review: Application is too difficult - Incredibly difficult application, following all instructions including putting in freezer did not help, thermal pad was stuck to the plastic and was ruined by the time I got it out, stick with paste, this is not worth the hassle, I can get a regular paste application done in under a minute, but this took me an hour and still failed horribly.
Review: Great stuff, it works quite well. A little tough to peel off the protective sheets thou. The trick I found was to peel off the harder to remove side first mostly to loosen it. Then peel the other side a bit at the opposite corner to loosen it and then you should be able to apply it without issues. I tested it against Arctic Silver 3 which is ancient and it was a lot better.

Este pad térmico funciona de maravilla. Mi laptop con Ryzen 5 5600H y RTX 3050 llegaba a los 99° aún con poca carga. Después de aplicar el pad no rebasa los 91° con CPU y GPU al 100% y con muy poco thermal throttling.
