This fixed my wife's laptop Dell XPS 15 9500 thermal throttling issue with a 10th gen intel cpu. I can turn intel turbo back on in the BIOS and runs it well below throttling/overheating limits. I was so impressed with the results, I applied it to my other 2 laptops Acer Swift 3 Ryzen 7 and Latitude 7480 also running with lower temps. I plan on applying this to my desktops in the future and hopefully replace paste altogether. Time will tell if it lasts a lot longer than paste. Tip on peeling off the film, stick in fridge for a little while to solidify (I did 5-10min) and use little pieces of scotch tape for pull tabs appy on each side of the cut piece making sure to apply the tape pull tabs to at least one corner on each side. Start on a corner picking/pulling the tape and peel off one side, apply to the die or cpu/gpu, flatten on chip, then repeat for the remaining film by picking/pulling on the tape. Will purchase again. Review: Creating a Permanent Phase Change Thermal Bridge to Survive Extreme Desert Heat. - I ordered this JOYJOM PTM7950 thermal pad for a friend's older ASUS laptop running an Intel Core i7 8750H processor. The computer was idling in the 70s and instantly slamming into its 88 degree thermal throttle limit the moment it was put under any real load. Traditional thermal paste is practically useless for these older gaming chassis out here in the brutal Indio summer heat. It just dries into chalk and pumps out over a few months of heavy thermal cycling. I was tired of applying standard grease just to have my friends asking me to redo their laptops every year and sounding like jet engines. The phase change material is totally different because it acts like a custom molded wax seal. It stays completely solid at room temperature which makes it incredibly easy to cut to size and peel the plastic film off with the included tweezers. The magic happens when the silicon hits 45 degrees Celsius. The pad actually melts into a highly conductive liquid that fills every microscopic scratch on the bare processor die. Once I applied over the direct die, the copper heatsink was perfectly seated against the chip before screwing it down with the provided screwdriver. You have to use a crisscross pattern to slowly squish the material down so you get maximum contact. To properly cure the material you have to run a heavy multi core benchmark for ten minutes to force the processor to maximum temperature. After three full cycles of heating the pad into a liquid and letting it cool completely off the laptop sat securely at 71 degrees under maximum load. That gave the processor a massive thermal buffer and stopped the fans from constantly screaming. It was so stable that I was able to leave the machine rendering and remote back into my home server to check on my own projects without worrying about the laptop overheating. The included cleaning wipes and brush made prepping the bare dies a breeze and the 40x80mm sheet gave me plenty of leftover material for future repairs. FYI, I used UPSIREN UTP-8 14.8w/mk Thermal Putty for the VRMs and VRAM chips, For the pictures, I show what it looked like after I took the heatsink off. There was way too much paste and putty everywhere. It even had thermal putty applied over two VRAM chip locations that weren't even installed (6GB instead of 8GB VRAM installed). I then show the PTM7950 and Upsiren thermal putty applied. Another shows Cinebench running and averaging only 71 degrees (HWiNFO64) Celsius when before the redo was idling in the 60s and 70s. I'll eventually redo my desktop with this. The last picture was Speccy showing the laptop only idling at 32 degrees after. This is night and day from what the laptop was doing before. PTM7950 is amazing and will outlast the silicon itself. ## Features - PTM7950 is a highly thermally conductive Phase Change Material (PCM) that lasts longer and is more effective than tradiational thermal paste. - Size 40x80x0.25mm, Phase change, Thermal Conductivity: 8W/m.K, - PTM7950 is a proprietary material that provides superior reliability and maintains low thermal impedance (<0.06K·cm²/W @ 30Psi), 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 40x80x0.25mm, 1x Phillips Screwdriver, 1x Cleaning Wipe, 1x Spatula, Finger gloves, 1x Cleaning Brush ## Technical Specifications | Specification | Value | |---------------|-------| | Best Sellers Rank | #13 in Silicon Grease | | Customer Reviews | 4.5 out of 5 stars 891 Reviews | ## Images ![PTM7950 40x80x0.25mm Phase Change GPU Thermal Pad - Image 1](https://m.media-amazon.com/images/I/414343I7d2L.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 ### ⭐⭐⭐⭐⭐ Cooling performance is great, highly recommended, especially for laptops *by J***Y on September 27, 2026* Regardless of the reddit reviews about this not being true PTM7950, it works great.

My Thinkpad P1 Gen 3 (infamous for overheating and thermal throttling) now is super cool, the thermal throttling is gone, even in games like cyberpunk 2077. The installation is quite tricky because the material is very soft, but the included sticker tabs are very handy. ## Frequently Bought Together - PTM7950 40x80x0.25mm Phase Change GPU Thermal Pad, JOYJOM High Conductive Silicone Grease 8.5W/mK CPU Thermal Paste for PS5 Steam Deck CPU GPU SSD M.2 Laptop - UPSIREN Ultra 16.8w/mk Thermal Putty for VGA GPU IC Processor Rapid Cooling Thermal Pad Replacement Heat Blocking Putty (20g) - 4 Pack 13W/m.K Thermal Pads, 100 x 100mm 0.5mm+1mm+1.5mm+2mm Silicone Cooling Pad Non Conductive Heat Resistance Extreme Odyssey Cover with Dual Self-Adhesive Films for PC Laptop PS4 --- ## 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.com.br/products/511232746-ptm7950-40x80x0-25mm-phase-change-gpu-thermal-pad](https://www.desertcart.com.br/products/511232746-ptm7950-40x80x0-25mm-phase-change-gpu-thermal-pad) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-10-02*
