Measuring 80x80x0.25mm with an impressive 8.5W/mK thermal conductivity, it minimizes thermal resistance and maintains reliability through rigorous testing. Included is a full installation kit, making it a professional-grade solution for gamers and tech enthusiasts seeking to optimize device cooling. ## Description Product Description PTM7950, a high thermal conductive Phase Change Material (PCM) in pad format, was designed to minimize thermal resistance at interfaces and has the great excellent long term reliability. Based on a novel polymer PCM system, this material exhibits excellent wetting at interfaces during typical operating temperature range, resulting in very low surface contact resistance. A proprietary filler material provides high thermal conductivity 8.5W/m ·K and a low thermal impedance (<0.04˚C cm²/W), suitable for high performance IC devices. how the PTM7950 thermal pad works ? At room temperature, thermal conductive phase change materials remain solid and cannot discharge air from the interface (Picture 1) As the temperature increases, the phase change thermal conductive material becomes softer and the air at the interface begins to be discharged, and the temperature also begins to decrease (Picture 2) When the phase change thermal conductive material reaches the phase change temperature(45°C), it becomes liquid and can greatly wet the interface, discharge the air inside the interface, reduce the interface thermal resistance, and transfer heat as much as possible; When the device is in a non working state, the phase change thermal conductive material becomes solid again, but maintains 100% complete wetting of the interface (Picture 3) Easy to use, Noted: thermal pad is gray, the protective film may be clear or blue, so it is normal if looks gray or blue Widely Application 8.5W/mK high heat dissipation performance.Effectively improve the performance of notebook computers, cpu, ssd, gpu game consoles or other integrated circuit chips. FAQ Q: Why did I receive it in blue, picture is gray? A: the thermal pad is gray, but protective film is blue or clear, please remove the film before using Q: Can it be used together with silicone grease? A: No, it needs to be used separately to replace silicone grease Q: Can it be used in multiple layers? A: No, it can only be used in a single layer. The standard thickness for applying silicone grease is 0.25mm. If it is too thick, it will affect the heat dissipation effect Q: Why is the cooling effect not obvious when used on desktop computer at the beginning? A: it is phase change thermal pad, when the thermal pad becames liquid in high temperature, it will have good heat dissipation, you can use the computer in high termperature 2-3hours and repeat many times to discharge air, the effect will be better. Q: How durable is the 7950? A: On mobile core gaming laptops, durability is very outstanding, and there will be no significant attenuation after one year of high intensity use (except for dust blockage and defects in the computer's own heat sink) Q: How long can the 7950 be stored? A: Sealed , avoid light, 2 year Review: Total Rubbish - Does not make any difference - temp went up 5C Sent back - Suspect this is a FAKE product looking at the way its cut Waste of money Review: This makes a difference! - Dropped the temperature on my steam deck by 6-7 degrees, much better than i was expecting. ## Features - PTM7950 is a super highly thermally conductive Phase Change Material (PCM) in both pad and paste formats. - PTM7950 Thermal Pad Size 80x80x0.25mm, Phase change, Heatsink Thermal Conductivity: 8.5W/m.K - PTM7950 Thermal Pad is designed to minimize thermal resistance at interfaces, maintain excellent performance through reliability testing, and provide scalable application at a competitive cost. - PTM7950 is a proprietary material that provides superior reliability (pass 150˚C baking 1000 hours, T/C-B 1000 cycles) and maintains low thermal impedance (<0.04˚Ccm2/W @ no shim), making the PTM7950 for high performance integrated circuit devices like cpu gpu ssd etc - Package include: 1x PTM7950 Thermal Pad 80x80x0.25mm, 1x Screwdriver, 1x Cleaning Wipe, 1x Spatula, Finger gloves, 1x Cleaning Brush ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BX42N9SZ | | Best Sellers Rank | 9,773 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 14 in Thermal Pads | | Brand | JOYJOM | | CPU Socket | Universal | | Cooler Heatsink Compatibility | Universal | | Cooler Heatsink Material | Phase Change Material | | Cooler heat sink material | Phase Change Material | | Cooler heatsink compatibility | Universal | | Country Of Origin | China | | Customer Reviews | 4.5 out of 5 stars 209 Reviews | | Included Components | PTM7950 Thermal Pad and kits | | Item Dimensions L x W x H | 8L x 8W centimetres | | Item Weight | 0.02 Kilograms | | Item weight | 0.02 Kilograms | | Manufacturer | JOYJOM | | Manufacturer Part Number | 80*80mm | | Model Number | 80*80mm | | Mounting Type | Chassis Mount | | Mounting type | Chassis Mount | | Product dimensions | 8L x 8W centimetres | ## Product Details - **Brand:** JOYJOM - **Cooler heat sink material:** Phase Change Material - **Cooler heatsink compatibility:** Universal - **Item weight:** 0.02 Kilograms - **Product dimensions:** 8L x 8W centimetres ## Images ![PTM7950 Thermal Pad Phase Change Heatsink 80x80x0.25mm 8.5W/mK Conductive for Heatsink PS5 Steam Deck CPU GPU SSD Silicone Grease Thermal Pad - Image 1](https://m.media-amazon.com/images/I/41bdLhDFe4L.jpg) ![PTM7950 Thermal Pad Phase Change Heatsink 80x80x0.25mm 8.5W/mK Conductive for Heatsink PS5 Steam Deck CPU GPU SSD Silicone Grease Thermal Pad - Image 2](https://m.media-amazon.com/images/I/61Xq0-9+tVL.jpg) ![PTM7950 Thermal Pad Phase Change Heatsink 80x80x0.25mm 8.5W/mK Conductive for Heatsink PS5 Steam Deck CPU GPU SSD Silicone Grease Thermal Pad - Image 3](https://m.media-amazon.com/images/I/61PGvOO5k-L.jpg) ![PTM7950 Thermal Pad Phase Change Heatsink 80x80x0.25mm 8.5W/mK Conductive for Heatsink PS5 Steam Deck CPU GPU SSD Silicone Grease Thermal Pad - Image 4](https://m.media-amazon.com/images/I/61-2337zqcL.jpg) ![PTM7950 Thermal Pad Phase Change Heatsink 80x80x0.25mm 8.5W/mK Conductive for Heatsink PS5 Steam Deck CPU GPU SSD Silicone Grease Thermal Pad - Image 5](https://m.media-amazon.com/images/I/31VUpII9NSL.jpg) ## Customer Reviews ### ⭐ Total Rubbish *by P***L on 8 August 2024* Does not make any difference - temp went up 5C Sent back - Suspect this is a FAKE product looking at the way its cut Waste of money ### ⭐⭐⭐⭐⭐ This makes a difference! *by G***E on 31 July 2024* Dropped the temperature on my steam deck by 6-7 degrees, much better than i was expecting. ### ⭐ Item not as described *by A***R on 24 May 2025* Was not 80mm x 80mm piece.
