## Overview

Thermal Grizzly PhaseSheet PTM is a cutting-edge thermal pad featuring phase change material that liquefies at 45°C to maximize heat transfer. Designed for CPUs, GPUs, and electronics, it offers exceptional thermal conductivity, adapts to uneven surfaces, and remains stable after multiple thermal cycles. Non-electrically conductive and easy to apply, it delivers reliable, long-lasting cooling performance that keeps high-performance systems running cooler and quieter.

## Description

PhaseSheet PTM is a thermal pad based on a Phase Change Material. The solid pads at room temperature can be easily applied and liquefy during operation, effectively dissipating heat like thermal paste while maintaining optimal thermal conductivity.PhaseSheet PTM adapts perfectly to uneven surfaces, ensuring even heat distribution. In its liquid state, it has very low viscosity and retracts back to its solid form, mitigating the pump-out effect.Even under extreme thermal loads, PhaseSheet PTM remains stable and delivers consistent cooling performance. Designed for high-performance systems, it ensures optimal temperature regulation even during intensive use. Available size: 50x40mm.

Review: Excellent Result - I used it on my Asus M16 gaming laptop which had metal thermal paste and its fans kept speeding up and laptop heating up even on light work. After repasting with PTM sheet, found noticeable difference and during normal use fans hardly ran to high speed. Thermals were much better as well. Also, used it on my brother GPU and temps dropped by 15 degree C and GPU did not hit thermal limits anymore.
Review: Solid product - Perfect product. Legit. CPU temps are very good. Just follow instructions. Just chill in fridge, do not freeze.
