It delivers a remarkable 58%+ sustained CPU power increase by minimizing thermal resistance with ultra-low viscosity in liquid state. Designed for long-lasting stability, it maintains peak thermal conductivity after multiple heat cycles, making it the top choice for silent, efficient cooling of CPUs, GPUs, and other electronics. ## 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. ## Features - PHASE-CHANGE THERMAL PAD FOR CPU AND GPU – PhaseSheet PTM is made as a clean alternative to classic thermal paste. - PTM MATERIAL FOR STRONG CONTACT UNDER HEAT – The interface adapts during operation and supports efficient heat transfer. - SUITABLE FOR CPU, GPU AND CONSOLE APPLICATIONS – Useful for repaste jobs, cooler swaps and maintenance on compatible contact surfaces. - PRACTICAL 50x40 mm FORMAT FOR FLEXIBLE USE – Can be cut to fit many applications and contact areas. - ELECTRICALLY NON-CONDUCTIVE FOR SAFER HANDLING – Designed for easy installation and stable thermal performance. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0DB84CQW6 | | Best Sellers Rank | #1 in Thermal Pads | | Brand Name | Thermal Grizzly | | Cooler Heatsink Compatibility | Broad range of coolers and heatsinks | | Customer Reviews | 4.5 4.5 out of 5 stars (1,748) 4.5 out of 5 stars | | Global Trade Identification Number | 04260711991059 | | Included Components | Thermal Pad | | Item Highlight | Phase-change thermal pad, PTM, CPU, GPU, consoles, strong contact, easy handling, non-conductive, paste alternative | | Item Weight | 20 g | | Manufacturer | Thermal Grizzly | | Model | TG-PS-50-40 | | Number Of Items | 1 | | Number Of Packs | 1 | | Part Number | TG-PS-50-40 | | Unit Count | 1 Count | ## Product Details - **Brand:** Thermal Grizzly - **Cooler Heatsink Compatibility:** Broad range of coolers and heatsinks - **Item Weight:** 20 g - **Manufacturer:** Thermal Grizzly - **Unit Count:** 1 Count ## Images ![Thermal Grizzly PhaseSheet PTM 50x40 mm Phase-Change Thermal Pad CPU GPU - Image 1](https://m.media-amazon.com/images/I/61Gc3girWqL.jpg) ![Thermal Grizzly PhaseSheet PTM 50x40 mm Phase-Change Thermal Pad CPU GPU - Image 2](https://m.media-amazon.com/images/I/81t3GiuJ66L.jpg) ![Thermal Grizzly PhaseSheet PTM 50x40 mm Phase-Change Thermal Pad CPU GPU - Image 3](https://m.media-amazon.com/images/I/91MiTCSdhdL.jpg) ![Thermal Grizzly PhaseSheet PTM 50x40 mm Phase-Change Thermal Pad CPU GPU - Image 4](https://m.media-amazon.com/images/I/917izFgiskL.jpg) ![Thermal Grizzly PhaseSheet PTM 50x40 mm Phase-Change Thermal Pad CPU GPU - Image 5](https://m.media-amazon.com/images/I/61j9OTf5nzL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great thermal pad *by on Reviewed in the United States September 1, 2026* I’ve been really impressed with this thermal pad. The 50×40 mm size is convenient to work with, and the material is easy to handle and position without making a mess. It adheres well once placed and provides excellent stability, so I didn’t have to worry about it shifting around.Most importantly, the temperature control has been excellent. It does a great job transferring heat and keeping temperatures under control, and it’s also completely silent since there’s no added noise. Overall, it’s very easy to use, stays in place well, and performs exactly as you’d want a high-quality thermal pad to perform. Definitely recommend it. ### ⭐⭐⭐⭐⭐ Reliable and Efficient Cooling *by on Reviewed in the United States June 4, 2025* If you're reading through reviews on this stuff, chances are you're looking to find out how it differs from standard thermal paste, and whether it's worth your time. Hopefully I can help you with that.Thermal Grizzly's Phase Change pads have many advantages over paste. Since I like to start reviews with the good, let's look at a few.Thermal paste dries out, and when it dries it loses its ability to conduct heat. It's a good practice to repaste every couple of years because of this. If you're the type of computer user who upgrades often, this probably won't apply to you since you're either getting rid of your old system before that paste dries, or you're constantly re-applying it anyway as you change cooling solutions or upgrade CPUs. On the other hand, if you like to run your systems as long as possible, these pads are for you--they DON'T dry out. Pretty nice stuff if you're going to be using them in a server or a system that won't see much in the way of regular maintenance.These pads also don't suffer from "pump out." Since your CPU and heat sink are usually made of different materials, they expand and contract at different rates. Over time, more and more paste gets pushed out until you've got areas with poor coverage. Phase change pads are solid at room temperature, and they turn into a sort of paste under high heat: your pads are expanding and contracting right along with your heatsink and CPU rather than being pushed out.I've repaired enough computers in my time to know that most of you don't apply thermal paste properly to begin with. Most folks fall into the "more is better" mindset and make a proper mess, like they're making a peanut butter sandwich. Others use far too little and have a lot of area uncovered. These pads take all the guesswork out of that by completely covering the die with a uniform layer.Also, if you're careful while removing your heat sink, you might be able to reuse the pad. It's solid at room temperature, remember, and it never dries out.If all that sounds good to you, here's how you use it.First, store the pad in the refrigerator until you're ready for it. It's solid enough at room temperature, but it'll rip less easily if it's cold. While the pad is chilling, remove your heatsink and clean off all that old paste. (Told you you use too much of it.) 99% rubbing alcohol works great for this. Take your pad out of the fridge, and line it up to your CPU surface. Use a Sharpie marker to mark off the length and width, then cut the pad to size.Now for the fun part: peel one side of plastic off the pad. Lay the exposed pad on your CPU, then press it down. Use your fingers to roll any air bubbles out of it. Then CAREFULLY... SLOWLY... peel the top plastic off. The pad is going to want to stick to the plastic more than it's going to want to stick to your CPU, so be patient with this. Once done, carefully install your heatsink (try not to slide it around, which might wrinkle the pad).Time to test temps, right? Well, no... not exactly. The pad needs a few hot/cold cycles in order to work its way into all the microscopic nooks and crannies. The general recommendation is to run a stress test for ten minutes, then power down the system to let things completely cool. Ten cycles like this is what most people recommend, but I've found four or five is enough. This is where Youtube reviewers tend to mess up, by the way: they'll slap on a pad, immediately run a stress test, then conclude the pads aren't as good as paste. Nothing could be further from the truth. Once cycled, you very likely will be getting lower temps than you would have gotten with tried-and-true paste.And you'll never have to apply it to that system again. That's my way of addressing the main disadvantage of the pads, which is that you could buy a tube of paste for what you're paying here. On the other hand, you're going to be applying that paste over and over again--and probably using too much of it anyway. (Don't worry, that's the last time I'll berate you for this.)The other downside is how meticulous you have to be about applying it. Just slow down and take your time. If the pad does rip, do your best to fix it and you should be fine.Highly recommended! ### ⭐⭐⭐⭐⭐ +58% sustained CPU power over paste on an Alienware X15 R2 — worth the fiddly install *by on Reviewed in the United States September 9, 2026* Repasted an Alienware X15 R2 (i9-12900H / RTX 3080 Ti) with this on both dies, replacing Arctic MX-5 that had gone in a few weeks earlier after removing Dell's factory liquid metal. VRAM/VRM got putty (Upsiren U6 Pro), fans were replaced at the same time. Linux box, so numbers are from turbostat and nvidia-smi.The metric that matters on this CPU isn't temperature — a 12900H pins at 100 °C on anything — it's how much power it sustains at 100 °C. Same 5-minute all-core stress test, same fan profile:MX-5: ~44 W at ~2560 MHzPhaseSheet, day 1: 65 W at ~3110 MHzPhaseSheet after ~10 heat cycles: 69.5 W at ~3150 MHz, in a warmer roomThat's +58% sustained package power from a TIM change. The CPU also drops from 100 °C to the mid-50s in about 25 seconds after load ends, which tells you the contact is good. GPU side held 87 °C max through a 20-minute FurMark + CPU soak at ~130 W with no throttling, though I changed graphics settings that same week so I won't quote a clean before/after for it.Install tips, because this is where people fail: put the sheet in the fridge 20 minutes first (not freezer). Cut it to size with both liners still on, slightly bigger than the die — overhang is harmless, it doesn't run. The second liner is the hard part; a tab of Kapton tape as a pull handle and a little warmth from a hairdryer so the film grabs the die makes it peel instead of tear. Don't spread it. And don't judge it on day one — mine gained 4 W between day 1 and day 2 as it settled.One 50×40 sheet covered both dies (roughly 24×15 and 31×22 mm cuts) with enough left for a retry. Bought this over generic PTM7950 because it's a branded product with real returns; there's a lot of fake 7950 out there and you can't tell from the packaging.Only downside is the film is fragile to handle. Once it's on, it's clearly the best non-liquid-metal option I've used in a laptop. ## Frequently Bought Together - Thermal Grizzly - PhaseSheet PTM (50x40mm)- High Performance Thermal pad with Phase Change Material | Durable, not electrically Conductive | for CPU, GPU & Electronics Cooling - Thermal Grizzly TG Putty Advance - 30 Gram - Electrically Non-Conductive Thermal Putty for GPU Modding and Thermal Pad Replacement - Thermal Grizzly Duronaut - 6 Gram - Enhanced Durability & High Performance Thermal Paste - for Maximum Thermal Conductivity While Overclocking CPU/GPU/PS4/PS5/Xbox --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/646450413-thermal-grizzly-phasesheet-ptm-50x40-mm-phase-change-thermal-pad](https://www.desertcart.hr/products/646450413-thermal-grizzly-phasesheet-ptm-50x40-mm-phase-change-thermal-pad) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-10-02*
