## Overview

Thermal Grizzly PhaseSheet PTM is a high-performance thermal pad featuring phase change material that liquefies above 45°C to create an ultra-thin, highly conductive layer. Its unique low-viscosity liquid state minimizes pumpout effects common in traditional pastes, ensuring stable and efficient cooling for CPUs, GPUs, and electronics. Non-conductive and durable, it sustains over 100% thermal conductivity through 10+ heat cycles, making it a reliable upgrade for professionals seeking long-lasting, maintenance-free thermal management.

## Description

PhaseSheet PTM basis phase change material is solid at room temperature. Material only starts to be liquefied at temperatures above 45 degrees Celsius. For optimal distribution of liquid PhaseSheet PTM and therefore to achieve the lowest possible layer thickness, a high contact pressure of approximately 300 to 400 N. PhaseSheet PTM is very low viscosity in liquid conditions and will shrink again when it changes to a solid material, minimizing the pumpout effect. Since silicone and copper are different in line expansion when heating, the pumpout effect is particularly noticeable when combining copper coolers with graphic chips. The temperature of the load causes the heat spreader and base plate to deform (concave or convex) and return to its original shape (straight line) when cooled. As a result, the thermal paste is slowly extruded between the heat spreader and the base plate of the CPU cooler. Excellent thermal conductivity Consistently high performance Extremely long service life Versatile for applications Not conductive Easy to use PhaseSheet PTM is more durable than traditional thermal paste but not as durable as KryoSheet. PhaseSheet PTM develops and stabilizes maximum thermal conductivity over 10 heat cycles over 60 degrees Celsius. Scope of Delivery Phase Sheet PTM 1 Piece

Review: 25年12月時点で、メーカー→代理店の正規ルートで入手できる唯一のPTMじゃないでしょうか？ 肝心のパフォーマンスについてですが、もう素晴らしいの一言です。 CPU：9800X3D、クーラー：360mm簡易水冷の環境で、グリスは某あるてぃめいとな美少女グリスを使用していましたが、このphase sheetに変えて見たところCinebench R23上で−5℃程度差が出ました。（グリスの方も塗布から半年も経ってなく粘性がしっかりと残っている状態だったのでコンディションは良好でした） 検証ガチ勢ではないので、室温などの影響も多少あるでしょうが、それでも冷却効率に差があることは確実かと。 1枚2400円と値段だけみれば高く感じますが、アリエクガチャの心配がない、グリスより冷える、定期メンテナンスから解放されることを思えば全然その価値はあると思います。というかグリスちまちま買い足す方がコスパ悪くね？と思います。 取り付け時のコツですが、冷蔵庫であらかじめ冷やしておくことです！ これによりフィルムを剥がす際に本体が破れてしまうリスクを減らせます。自分は10分弱冷やしましたが、特にトラブルなくスムーズに貼り付けできました。
