## Overview

PhaseSheet PTM is a cutting-edge thermal pad featuring phase change material that liquefies at 45°C to maximize heat dissipation. It offers superior thermal conductivity, easy application, and long-term stability without electrical conductivity risks, making it ideal for CPUs, GPUs, and advanced electronic cooling systems.

## Description

Product Description High-End Phase Change 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. Optimal Adaptation 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. Consistent Performance Under Extreme Conditions 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: Simply put, it works and it's legit. - Works VERY well. I used this PTM on a Minisforum BD795i SE Motherboard so not a traditional CPU. It worked very well on direct CPU-die similar to how a GPU would work. I personally found it easy to apply but I can see people making mistakes if not careful when peeling. Temps are very good however it took around 3 days to finalise. At first then temps looked similar to before however they DID improve. I have tested genuine Honeywell PTM in the past and this performed identical. Great value and authentic.
Review: Highend thermal compound for CPU delid-relid job, without electric shortcut risk of liquid metals - I delidded my i7 7800X, and put this staff between the core and the lid, as the paste applied by Intel was really bad quality. Custom watercooling loop with 1080Ti GPU. The loop is fine, as the GPU max was 40C. Before the job, the CPU went on 60-70C in idle, and peaks were well over 90C. Now idle 35C, in load 60-66, and no peaks at all. Easy to cut and apply on, it's just as sticky, as it needs to be. End one sheet could be enough for a CPU core (under the lid), and for a GPU. It lasts longer than paste, and it's not electrical conductor, but brings the same effectivity as the liquid metals. Price... it's not worse then other highend compounds.

### ⭐⭐⭐⭐⭐ Great product, put in freezer to harden up before applying
*by C***S on 21 June 2026*

Works great in my processor, I changed the standard CPU bracket for my 12th gen to a contact frame for better contact with my all in one liquid cooler, and this phase sheet together has knocked about 15 degrees off my highs. It can be a bit of trouble putting it on if you do it with the phase sheet at room temperature, so put it in the freezer for 10 minutes to harden it up and make application easy. All in all, it’s great and one less thing to worry by having the thermal sheet cover all of the processor and not rely on a guess amount of thermal paste.
