  • 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 ?

thermal pad

At room temperature, thermal conductive phase change materials remain solid and cannot discharge air from the interface (Picture 1)

thermal pad

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)

thermal pad

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)

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

I don't know if its legit PTM7950 but it works great and brought my GPU temps in line after previous paste pump out.

It's not that hard to apply as long as you don't believe people about the mythical hidden layers. Either it has blue plastic on it, or it does not.Use a razer to lift the plastic from it, grab it (harder than it sounds, but not that hard). Then apply it to whatever and peel off the other piece. Then screw the heatsink back and it get snug. Don't look under it again unless you want to repeat the process. My X3D CPU is plugging along with no FPS drops. It may not be the exact same as on some websites but I think it is legit.I have no idea why it includes all these tool things. The screw driver is too short for CPU coolers or too small. The brush? huh? Use isopolypropylene alcohol if you need to clean your surface.Side benefit, you get enough to do more than one item.

This stuff is phenomenal! I used it to repaste a 7900XTX that was having hotspot issues. My hotspot was 100c with the fans running at 80% and the power limit set to -10% AND a healthy undervolt.The PTM7950 was easy to apply. I put it in the fridge for about 30 minutes before I applied it, measured the size of the GPU surface and cut it with a Fiskar's knife. pulled the bottom film off with tweezers and set the pad down, smoothed it over with a spatula, then pull the top film off with tweezers again. THAT took a few tries to get a good grab on the film but I got it!Now I can set the PL +10%, leave the fan curve stock and my hotspot never goes beyond 80c.

Dropped GPU temps on an aging RTX 3080 by 4-5 degrees, which is pretty significant for TIM. More notably it dropped the hotspot temp by 15 degrees. That being said, during the first day or two after application I was a little skeptical as the GPU temps increased a little even after going through a dozen or so heat cycles right after applying. After giving it a week or so to settle I am extremely impressed by the results overall and would consider using this for a CPU application. Installation isn't as bad as some make it seem. On the weirdly shaped heat spreaders for some newer Ryzen CPUs it might be awkward though.

The package could be in a bad condition, since it's shipped from Maharashtra. But I got it in a good condition. A little of PTM melted and flowed out too, but that's not too much of a deal. There's more than enough PTM for you do 2 repastes.

I found that the thermal material worked super well for both my GPU, which was suffering from really high hotspot temps, and for my laptop's CPU. It was pretty easy to apply, although the plastic covering it was a little finicky at times. I just cut it into the right size with a box cutter, and applied using the little adhesive tabs that came with the kit to lift off the plastic covering.My laptop CPU's performance increased by 20% compared to its old dried out paste, since it was no longer throttling. And, it applies cleaner than any traditional paste ever will. Definitely going to be using this stuff in the future for GPUs, and maybe even a desktop CPU when I upgrade.

Necesito documentar esto,porque no lo he visto mucho.tengo una RX 7600 no tiene mas que algunos meses y jugando GOW en graficos normales a 120 alcanzaba temperatura de entre 76 a 80 c normal pero el hot point llegaba a 100, y los ventiladores a tope.intente muchas configuracione sy undervolt pero no logre mejorar el hotspot para nada.despues recorde este producto y que muchas gpu tienen un problema con la pasta termica que le ponen, me arriesgue y se la puse y vaya sorpresa (la pasta de fabrica ya venia dura).las temperatura en juego las veo mas en los 65 a 75 a veces 80 pero es raro, y el hotspot llega a los 90 pero baja rapidamente, manteniendo una delta de 15 grados.se que mi garantia ya no existe pero por esas temperaturas, los ventiladores mas silenciosos y por no preocuparme por cambiarlo en toda la vida util de la gpu vale la pena

Habe mir dieses Thermopad gekauft da meine Red Devil RX 6800 XT immer eine 25-30° höhere Hotspot temperatur hatte als die normale Temperatur.Man muss sagen dass das Auftragen für jemanden der das zum ersten mal macht etwas fummelig ist - ich habe mir extra dafür eine kleine Pinzette zuvor gekauft und für mich war es das auf jeden Fall wert.Nun gut was sagen die Temperaturen nach den Wechsel auf die PTM7950?Cyberpunk 2077 1440P alles auf Max, kein Raytracing - GPU ist Übertakted und zieht ca. 330W.Voher: GPU Temp: 75° Hotspot: 97-105°Nacher:GPU Temp: 70° Hotspot: 85-89Ich bin wirklich überrascht wie gut Thermopads geworden sind, damals hieß es ja quasi immer nur das Thermopads soviel schlechter seien als Paste, aber diesen Unterschied hätte ich wirklich nicht erwartet.Achtung: Das Thermopad brauch einige Zeit(Bei mir waren es 2-3 Tage) mit Last bis man die wirklich richtigen Temperaturen sehen kann, es muss sich quasi etwas verflüssigen und sich besser auf den Chip verteilen was evtl. etwas dauern kann - allerdings hat man hier den Vorteil das sich die Temperatur nicht mehr verschlechtern wie bei Wärmeleitpaste nach einigen Monaten, für die Langlebigkeit auf jeden Fall top!

I am having a hard time accepting how good this actually is. I have a G513QU gaming laptop which, unfortunately, was one of the serial numbers with the faulty liquid metal solution and after a year or so it had pumped out enough that the clocks were not boosting to nearly the speeds that it was when it was new. I decided to crack it open and replace it myself instead of sending it back to Asus RMA as I know Asus has made it their life's mission to make the RMA process as horrible as possible.I opened the laptop up and took out the liquid metal and the faulty barriers. I prepped the SMDs around the dies for liquid metal and got to the point where I wasn't confident on making my own barrier so I just put paste on it to see how that went - it went poorly. My temperatures were high and clocks were low. I then found out about PTM7950 after doing some research and decided to give it a go.This stuff was pretty hard to work with before I figured it out so expect a trial run before you actually get it right. I bought a cutting mat, measuring tool, and a craft knife to get it done correctly. I measured the dies and then cut accordingly. Getting on was a bit tricky but once you learn to use tweezers to set it properly on the die and lift up from the corners to get the film off it actually is not hard to work with.Once it was on I put the laptop together and was shocked at how good my temperatures were. I added some spacers to increase the mounting pressure and with those plus the PTM7950 I am getting better temps than I did with the original liquid metal application. Now, obviously the increased mounting pressure is doing some work here but I had that going with the normal paste and my temperatures weren't even close to as good as with the PTM7950. Now, my clocks boost to max speed and even though the CPU is designed to boost to 95c and hold it actually only get to about 92c which is absolutely bonkers. The GPU is doing great as well and there is zero throttling on the laptop. I was able to pass a 20 minute time spy stress test which I was unable to do with the paste application. This stuff is absolutely amazing.One last thing to note. I did two applications where one had the PTM7950 completely covering each die and the next I uses a bit less because there was a lot of pump out meaning that there was too much used. Well, covering the full die was better as I guess the pumped out bit can catch heat coming off the sides and pipe that to the heatsink so I would definitely cover the entire surface area of the die if you're doing direct die cooling.One last thing, in the videos of people using the actual Honeywell PTM7950 the pads are a bit thicker (0.25 vs 0.2 mm) and the colour is blue versus the grey of this. I was skeptical that this isn't PTM7950 because of that and I don't know what it actually is but it cools significantly better than good thermal paste so I am guessing it is a knockoff but still the same formula.A bit expensive but totally worth it.

I applied some of the pads to a Lenovo ThinkPad X1 Yoga and my Ayaneo 2. While my ThinkPad temps didn't really improve all that much, under stress testing the overall performance increase on the Intel i7-1280P is up 400MHz but the cooling solution for it is at it's maximum potential against that CPU. Once the laptop and surface get heat soaked, it's just going to creep up, hit 85C, thermal throttle, rinse and repeat. I don't blame the PTM7950 on this, just the cooling solution not being able to keep up with worst case scenario. That being said though, it has rejuvenated my Ayaneo 2 handheld. When I applied it, put it all back together, and fired up Doom 2016 at 30W TDP, I noticed that the amount of heat being rejected was hotter while the fan speed was slower; telling me that the temp requirements were being met more efficiently. I'm probably going to do this to my RTX 3070 Ti to see if I get some more frequency improvements like my ThinkPad.

I was apprehensive about buying this unbranded PTM 7950, but LTT Store has been out of stock for some time now.. Weather or not this is the legit Honywell stuff, it seems to work very well! Right out of the box, it's working as well or better than my MX-6. My previous paste application was approaching two years old, but didn't seem to be showing worse temps. I found that the coverage of my last application was 100%, with very little excess, so best case scenario. After several hours of break in, temps have improved maybe another couple degrees C. Not going to wait five years to see if it lasts forever before reviewing, so I'm already satisfied with the results.I wish they gave you more material and less accessories. I didn't even open the other stuff they included. 40x80mm is exactly enough for two applications on a Ryzen 5000 series. Not sure if the newer ones are any bigger. A GPU maybe bigger too.

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.
