## Overview

Thermal Grizzly PhaseSheet PTM is a cutting-edge thermal pad featuring phase change material that solidifies at room temperature and liquefies at 45°C for optimal heat transfer. Designed for CPUs, GPUs, and other electronics, it offers exceptional thermal conductivity, non-electrical conductivity for safety, and long-lasting stability after multiple thermal cycles. Ideal for professionals seeking reliable, high-performance cooling solutions that adapt perfectly to uneven surfaces and maintain peak system efficiency.

## 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: Great performance, but not for ametuers. - Used this to replace the paste on both CPU and GPU on my Alienware X15 R2. Took 3 hours to do, and I also cleans the fans whilst everything was apart. Glad I did it, as the Element31 on the CPU looked like it was leaking out of the CPU dam. the GPU Paste was rather dry and crumbly. After completing the service, the laptop is running lots cooler (mainly the fan cleaning) but the GPU is also running cooler, and the i9 cpu is able to run up to higher clock speeds. It's been on for several days, has been getting better each day. 4 days after install, my CPU is now running with an average core temp of under 84C, when had multiple cores bouncing at 100C. For application I put it in the fridge for a couple of days before opening the case, used a pair of scissors to cut the sheet to the correct size for each chip and and was able to peel off the plastic without ripping things, though you do have to be careful with it, as it's thin and delicate. I feel confident that my laptop has been given a new lease of life, and it's running as cool as when I first got it. Whilst this stuff isn't cheap, I think the performance and peace of mind that I'm not going to have a gallium leak makes it worth the cost. Time will tell how long it will last, that said if I get 5 years out of it, I'll be really happy, and everything I've seen so far leads me to think that it's going to do that and a whole lot more. I'm interested to see what the temps are like when it stops bedding in.

### ⭐⭐⭐⭐⭐ Highend thermal compound for CPU delid-relid job, without electric shortcut risk of liquid metals
*by A***J on 5 April 2026*

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.
