desertcart.com: 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 : Electronics

Review: Reduced my temps significantly at a great cost to performance ratio. - Great value thermal pad/paste. PTM is a phase change material that allows it to be applied as a thermal pad and with heat it will change into a paste. I have bought a few sets of these, and applied to 3 gpus, 2 laptops, a handheld, and my main computers CPU (did not delid, just used it in place of regular paste). I will mention, there is some talk on reddit about the JOYJOM PTM7950 not actually being true PTM7950. I am not that experienced that I would be able to tell the difference, but overall sentiment was that it still performs similarly enough that you will see good results. Adding that with the value of this brand being much cheaper than trying to go through other channels to get the guaranteed stuff, this is a no brainer for most. I noticed huge temperature drops in my Asrock RX 6900 XT and EVGA RTX 3080. I didn't use my i7 13700k without the JOYJOM PTM paste so I can't compare there, but I have not experienced any throttling and the temps are better than I expected with all the issues on the chip. My MSI GE66 Raider 11UE, my partners old Razer Blade 16, and my GPD Win 4 all also saw major temperature drops using these pads on their CPU and GPU's. This resulted in less noise as the fans didn't have to ramp up as high, and better performance. The kit these come with is also handy. I don't really use the finger gloves, but I could see them being nice if you have nice nails and don't want to get paste on them. The cleaning wipes and little brush are a nice touch as there is a good chance you will be cleaning off old paste with the install and these will help you clean up easily. I can safely recommend this to anyone looking to re-paste their computer/parts. I plan to continue buying this as needed myself as its performed well in my tests.
Review: 100% will buy again - This product works really well.On my gaming laptop with the original thermal paste that it came with from factory, I would see my CPU temperatures usually around 180F-200F. I did not like this at all and it’s very bad for your components. When I bought this product, I cut it up into two small squares and wiped off the old thermal paste and put each square on my GPU and CPU. I am really surprised the difference it made. Now when I use my laptop, the CPU temperatures are usually around 155-175F and my CPU doesn’t thermal throttle. I would 100% buy this product again in two or three years when it’s time to replace it.

## 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 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 40x80x0.25mm, 1x Phillips Screwdriver, 1x Cleaning Wipe, 1x Spatula, Finger gloves, 1x Cleaning Brush

## 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

### ⭐⭐⭐⭐⭐ Creating a Permanent Phase Change Thermal Bridge to Survive Extreme Desert Heat.
*by M***Z on February 15, 2026*

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.
