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: Works amazing! - I bought this for the steam deck to see if I could drop the temperatures as I've heard good reviews on this phase changing thermal paste. All I can say is the photos literally show proof that this stuff works, I have added a before and after photo, game tested was Ragnarok. CPU temperature dropped about 7c Whilst the GPU drop a crazy 13c Literally looks for your self. I'm very happy with this purchase and will definitely be buying more for anymore future projects of mine :) Review: You can stop searching now, this is the best thermal paste for your PC - I was very skeptical at first of this new "PTM" stuff I kept hearing about, so I decided to pick this up to try it with my new PC that's having thermal issues (it's my first Mini ITX build). I removed all the paste from my CPU and placed the PTM on it, remembering to remove the film from both sides, and tightened the cooler down on it. I could tell the difference IMMEDIATELY. My computer booted and dropped me to my desktop without me even realizing it because the fans never kicked up like they nomrally do. I ran a CPU stress test on my Ryzen 9 7940HX and where I was normally bouncing off my processor's TjMax within 5 minutes, I was now about 10 degrees (centigrade) below it after 20 minutes! Amazed at the improvement, I removed my GPU and swapped the paste for the remainder of the PTM - Another brilliant decision, because now my GPU won't even cross the 70 degrees centigrade mark even under full load! In an ITX build! I'd give this 10 stars if I could. It doesn't make a mess, there's no need to spread it around, it performs on-par or better than liquid metal, and your thermals will actually IMPROVE over time. I see absolutely no reason this shouldn't be used in any device you can repaste. In fact, I actually bought more and now all of my computers run this. If you're struggling to decide what paste to get, you can stop now and purchase this knowing it's exactly what you're looking for. ## Features - PTM7950 is a highly thermally conductive Phase Change Material (PCM) that lasts longer and is more effective than tradiational thermal paste. - Size 31x50x0.25mm, Phase change at 45°C, Thermal Conductivity: 8.5 W/m.K, It is normal for it to melt at high temperatures.It achieves good heat dissipation performance through repeated melting and solidification. Note: it requires technical and operational skills, it is recommended to use under the guidance of professionals - 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 series desirable for high performance integrated circuit devices. - PTM7950, based on a novel polymer PCM system, exhibits excellent interface wetability during typical operating temperature ranges, resulting in extremely low surface contact resistance. - Package include: 1x PTM7950 Thermal Pad 31x50x0.25mm, 1x Screwdriver, 1x Cleaning Wipe, 1x Spatula, Finger gloves, 1x Cleaning Brush ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CQ7F829H | | Best Sellers Rank | 86,720 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 144 in Thermal Pads | | Brand | JOYJOM | | CPU Socket | Universal | | Cooler Heatsink Compatibility | Gaming Consoles, Laptops, Desktop Computers | | Cooler Heatsink Material | Aluminium | | Cooler heat sink material | Aluminium | | Cooler heatsink compatibility | Gaming Consoles, Laptops, Desktop Computers | | Customer Reviews | 4.6 out of 5 stars 204 Reviews | | Included Components | 1x PTM7950 Thermal Pad 31x50x0.25mm, and tools | | Item Dimensions L x W x H | 5L x 3.1W centimetres | | Item Weight | 0.05 Kilograms | | Item weight | 0.05 Kilograms | | Manufacturer | JOYJOM | | Manufacturer Part Number | 31x50x0.2mm | | Model Number | 31x50x0.2mm | | Mounting Type | Chassis Mount | | Mounting type | Chassis Mount | | Product dimensions | 5L x 3.1W centimetres | ## Product Details - **Brand:** JOYJOM - **Cooler heat sink material:** Aluminium - **Cooler heatsink compatibility:** Gaming Consoles, Laptops, Desktop Computers - **Item weight:** 0.05 Kilograms - **Product dimensions:** 5L x 3.1W centimetres ## Images ![PTM7950 31x50x0.25mm Phase Change Thermal Pad, JOYJOM High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck ROG Ally CPU GPU SSD M.2 Laptop - Image 1](https://m.media-amazon.com/images/I/516E+EmNHUL.jpg) ![PTM7950 31x50x0.25mm Phase Change Thermal Pad, JOYJOM High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck ROG Ally CPU GPU SSD M.2 Laptop - Image 2](https://m.media-amazon.com/images/I/61Xq0-9+tVL.jpg) ![PTM7950 31x50x0.25mm Phase Change Thermal Pad, JOYJOM High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck ROG Ally CPU GPU SSD M.2 Laptop - Image 3](https://m.media-amazon.com/images/I/61Xcyi5y8WL.jpg) ![PTM7950 31x50x0.25mm Phase Change Thermal Pad, JOYJOM High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck ROG Ally CPU GPU SSD M.2 Laptop - Image 4](https://m.media-amazon.com/images/I/51dvdMHenoL.jpg) ![PTM7950 31x50x0.25mm Phase Change Thermal Pad, JOYJOM High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck ROG Ally CPU GPU SSD M.2 Laptop - Image 5](https://m.media-amazon.com/images/I/51RJaoXY3nL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works amazing! *by S***. on 10 October 2024* I bought this for the steam deck to see if I could drop the temperatures as I've heard good reviews on this phase changing thermal paste.

PTM7950 after application was able to reduce 20°c from the hot spot of my AMD RX 7900 XTX. Also I have seen videos where the temp would go down on further usage. Be careful in applying it. It has potective film on either side, so keep in the freeze hox for a bit of hardening where the removal becomes easy. Use the removal stickers included in the package to peel off the protective film on either sides and best thing is to use a tweezer if you have delicate hands. ## Frequently Bought Together - PTM7950 31x50x0.25mm Phase Change Thermal Pad, JOYJOM High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck ROG Ally CPU GPU SSD M.2 Laptop - UPSIREN 12.8w/mk Thermal Putty for VGA GPU IC Processor Rapid Cooling Thermal Pad Replacement Heat Blocking Putty High Performance (10g) - ARCTIC MX-6 (4 g) - Ultimate Performance Thermal Paste for CPU, Consoles, Graphics Cards, laptops, Very high Thermal Conductivity, Long Durability, Non-Conductive --- ## 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.co/products/608348996-ptm7950-31x50x0-25mm-phase-change-thermal-pad-joyjom-high-conductive](https://www.desertcart.co/products/608348996-ptm7950-31x50x0-25mm-phase-change-thermal-pad-joyjom-high-conductive) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-05-27*
