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: Re-paste my laptop Legion 5 Pro 2021 - Took a risk buying this, there were 3 issues: - Product listing has "Brand: JOYJOM" but the paste should have been made by Honeywell. - Cost (I paid £25.46) is far higher than any thermal paste I know of. - Posted from China or USA (I can't tell), not sure how I'd get a refund if it's not right. I used it to re-paste my laptop Legion 5 Pro 2021 16ACH6H because the processor reached 104°C using Arctic MX4. It worked as you can see in my screenshot attachments (they were running Cinebench r23) and reducing the temps in some of my games by up to 20°C. They provided provided tools but I think they were inappropriate, why do I need a screwdriver and a brush? They should have provided a tweezer instead to remove the plastic covering the pad. Review: Doesn't appear to be good quality - So I picked this up keeping my fingers crossed it's real PTM7950 (which is generally hard to come by) and unfortunately, looking at the temp results, it's not. I repasted my CPU and GPU with this stuff, expecting to see some substatial temp changes. It's reasonably well packaged and relatively easy to use (super thin layer, so it can be fiddly). Unfortunately, however, after repasting and running some benchmarking tests including Cinebench, AIDA64, and 3D Mark, I was disappointed to find the temps were worse than the stock thermal paste. I then repasted with Arctic MX-5 and saw a significant improvement. I'm running an i9 and an RTX 4090m (laptop). Results were (with no overclock): Stock idle: 55oc Stock Load: 90oc This stuff idle: 58oc This stuff load: 95oc Arctic idle: 47oc Arctic load: 84oc I don't know, maybe I got a bad batch here, but it really didn't perform as expected. I'd suggest looking for other sellers. ## Features - PTM7950 is a highly thermally conductive Phase Change Material (PCM) that lasts longer and is more effective than tradiational thermal paste. - Size 40x80x0.2mm, Phase change at 45°C, Thermal Conductivity: 8.5 W/m.K, - 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 Thermal Pad 40x80x0.2mm, 1x Phillips Screwdriver, 1x Cleaning Wipe, 1x Spatula, Finger gloves, 1x Cleaning Brush ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BRJB8JNX | | Are Batteries Included | No | | Best Sellers Rank | 117,720 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 184 in Thermal Pads | | Brand | JOYJOM | | Customer Reviews | 4.4 4.4 out of 5 stars (738) | | Date First Available | 11 Jan. 2023 | | Guaranteed software updates until | unknown | | Item Weight | 59 g | | Item model number | 01 | | Manufacturer | JOYJOM | | Package Dimensions | 15.29 x 10.21 x 2.69 cm; 59 g | ## Images ![JOYJOM PTM7950 40x80x0.2mm Phase Change GPU Thermal Pad, High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck CPU GPU SSD M.2 Laptop - Image 1](https://m.media-amazon.com/images/I/414343I7d2L.jpg) ![JOYJOM PTM7950 40x80x0.2mm Phase Change GPU Thermal Pad, High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck CPU GPU SSD M.2 Laptop - Image 2](https://m.media-amazon.com/images/I/61Xq0-9+tVL.jpg) ![JOYJOM PTM7950 40x80x0.2mm Phase Change GPU Thermal Pad, High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck CPU GPU SSD M.2 Laptop - Image 3](https://m.media-amazon.com/images/I/51gpYfiNz7L.jpg) ![JOYJOM PTM7950 40x80x0.2mm Phase Change GPU Thermal Pad, High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck CPU GPU SSD M.2 Laptop - Image 4](https://m.media-amazon.com/images/I/51-boJqGRvL.jpg) ![JOYJOM PTM7950 40x80x0.2mm Phase Change GPU Thermal Pad, High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck CPU GPU SSD M.2 Laptop - Image 5](https://m.media-amazon.com/images/I/61986oBc1sL.jpg) ## Questions & Answers **Q: Is PTM7950 good replacement for thermal paste for laptops?** A: Sure. you can use those pads as a replacement for regular thermal paste one your laptop or desktop computer. PTM 7950 is probably the best thermal paste you can buy for a laptop right now. I tested it on my Dell G15,it performs admirably and beat the OEM thermal paste used by Dell in my laptop I would highly recommend this PTM7950 thermal pad to anyone who has an overheating laptop **Q: how's the performance?** A: So far seems to be extremely good. Applied this on a Dell XPS15 9570 laptop, the temps have dropped by around 15 degrees. and this product seems to stay within good price! If you need moderate price thermal conductivity thermal pads, I would recommend this thermal pad! Worth a try **Q: Hey, how is this comparable to "Honeywell" 7950 phase change thermal pad. Is this the same thing?** A: I've installed it in a very hot trashcan Mac Pro in both GPUS and CPU and the temperatures have dropped by around 15 degrees. to the point that I can overclock the GPUs safely in windows. I'd say the performance is incredible but I can't say for certain if it's as good a one sold by the name brand Honeywell. but from reviews I've seen on YouTube and other commenters on other websites seems like these are also Honeywell, just sold in bulk to resellers. **Q: Just recently replaced my paste with these pads on my laptop.Should i be concern if i made a cutof the pads thats bigger than the cpu die?** A: No. It's not electricaly conductive. It's safe ## Customer Reviews ### ⭐⭐⭐⭐ Re-paste my laptop Legion 5 Pro 2021 *by T***M on 20 January 2024* Took a risk buying this, there were 3 issues: - Product listing has "Brand: JOYJOM" but the paste should have been made by Honeywell. - Cost (I paid £25.46) is far higher than any thermal paste I know of. - Posted from China or USA (I can't tell), not sure how I'd get a refund if it's not right.
