PTM7950 40x80x0.2mm Phase Change GPU Thermal Pad, YEZriler 8.5W/mK High Conductive CPU Silicone Grease Thermal Paste for Game Machine CPU GPU SSD Laptop

No creo que sea producto original honeywell, pero hasta ahora ayudó a mantener las temperaturas de mi 4080 por encima de los 90°c en el hotspot, recomiendo meterla al refrigerador 1hr antes de usarla o 20min en el congelador para que no se adhiera en tus dedos/herramienta durante la instalación

He usado honeywell de diferentes proveedores. Esta venía extremadamente pegada a las dos capas protectores. Casi imposible de remover. Ni usando el método de enfriarla en el refrigerador. Además de que sólo venía en una bolsa, por lo que venía medio maltratada.

I’ve used PTM7950 thermal pads on multiple devices, from gaming laptops to GPUs, and the results speak for themselves. This stuff is next-level compared to traditional thermal paste—it’s easier to work with, less messy, and delivers serious cooling improvements.Why It Works So WellThis isn’t your typical thermal pad—it’s a phase change material, meaning it stays solid at room temp but melts slightly at around 45°C, filling in microscopic gaps for superior heat transfer. The difference is noticeable! My GPU and CPU temps dropped by several degrees, and I’ve seen fan speeds decrease because the system doesn’t have to work as hard to stay cool.Pro Tips for Applying It✔️ Put it in the fridge or freezer for a bit before applying. This makes it easier to handle and prevents it from stretching or losing shape.✔️ Use a spudger or plastic tool to remove the protective film from both sides—it’s delicate, so take your time.✔️ Peel the bottom film first, place it on the CPU/GPU, then remove the top film before reassembling.Final ThoughtsIf you’re serious about keeping your components cool, PTM7950 is worth every penny. It lasts longer than paste, doesn’t dry out, and keeps performance consistent over time. Highly recommend for Steam Decks, gaming laptops, or high-performance GPUs!

Looks legit, packaging is good. Will definitely buy again. Only thing is if you can give extra wet alcohol wipes , would be perfect. One is not enough to get rid of old paste residue.

This thing in terms of appearance (the plastic protective sheets) and performance seems to be very similar to Gelid Heatphase (which for all that I know could just be rebranded Honeywell PTM7950). I tested on a 7900X w/ a Asus TUF X670e wifi ("multicore enhancement" disabled, so it draws ~130W package; room temp of 82-83F, there's a bit of a heatwave when I tested this on a test bench between different pastes) using an ID Cooling 280mm AIO. In Cinebench R23, all 3 performed similar (as expected) or ~72C average (this shouldn't be directly compared to other results outside of the 3 different thermal interface materials I've used), and this new paste was within margin of error of my Gelid Heatphase.For those of you who are wondering what this is for, it's a thermal paste replacement. It's not really a thermal pad, and should not be directly compared to something like Thermal Grizzly's Kryosheet, since unlike the Kryosheet, this does turn more "fluid" under higher temps. Phase change material (like the Honeywell PTM7950) addresses a major issues of thermal paste: dryout and pump out. A short version, dryout happens when the fluid part of thermal paste (usually silicon grease) over time, while pump out happens from the thermal expansion/contraction of the heatsink and CPU IHS causing the heatsink to warp and push paste out. Since phase change material only liquifies under higher temperatures, it performs better but lasts significantly longer than thermal paste (on paper it's not as performant as liquid metal, but it doesn't differ as much and liquid metal has other issues, such as aging and, well, conductivity). It makes more sense for a laptop (Lenovo has been using PTM7950 in their Legion laptops since 2022) or for a computer where you know the person using it won't be maintaining it a lot, but it can improve performance relative to paste. Why do I include this part? Because I also reviewed the Gelid Heatphase and some reviews really show people do not understand what this is for. In terms of how much you're getting for a 40*80mm, the cut in the sheet is slightly smaller than the non-outer-edge area of an AM5 CPU's IHS (it is enough for an AM5 CPU). You can in theory "reuse this" by scraping it off with a plastic spudger and evenly applying the bits over the new CPU/GPU, I have done this before several times with PTM7950 (because this stuff is expensive), it doesn't seem to affect performance.Included is a kit to help you apply this. You don't really need it. Unlike most of the packaging that I've seen PTM7950 come out of, the plastic sheet (just like the Heatphase) comes off very easily. The included sticker pack will help out if you have trouble removing it either with a thin spudger or your fingernails. If your room temperature is pretty hot, you can put this thing in the fridge some time before applying it, since it does harden a bit when it's cold.Overall, this thing seems to be legit, or at least, it performs like it's legit. At the time of this review it's $16 w/ a 20% discount coupon, so not bad, but heaps more expensive than paste. If you're someone new to PC building, I would suggest going with a thermal paste because it's just easier to apply and is more economical, but if you recently heard of the phase change material bandwagon, or alternatively is building a PC for someone who doesn't maintain it much, this does seem to offer legitimate performance.

If you want it to be a little easier to handle when applying, get it cold first, put it in the fridge/freezer and that makes it so much easier to deal with. Awesome stuff, it's usually either on par with good pastes or better but once you put this on you can forget about it, no squishing out over time or going bad and hardening up in a year or two, this stuff will outlast whatever you use it on.

I have an aorus 15 gaming laptop and the thermal paste that came on it was not cutting it. I switched it to liquid metal which is the coolest it's ever been but liquid metal seeps out and dries and I have to replace every 18 months or so which is a pain. This should provide really good cooling without having to worry about paste drying, especially in a laptop or the metal seeping out. Definitely glad I switched to this. I had plenty of material.The only downside is it's not super easy to peel the protective plastic off and I had to redo the application non the cpu.

Works perfectly well. Make sure to place it in the freezer for about 30 minutes to get some consistency before placing it on the motherboard. This will allow you to cut it perfectly and install it without issues. Otherwise it will likely smear all over the place and be a mess to work with.

I was using Honeywell's 107408 heat conductive compound on my CPU heatsink before installing this product. That is the stuff they have using for many decades in the insertion wells of temperature probes in building automation systems. With this PTM7950 Honeywell product I was not sure what additional benefits I might see. Running the Intel Diagnostic Tool stress tests on the I5-10400 processor, maxed out under 100% loading, I did not see much, if any, change in the reported temperatures of the various cores as compared to the 107408 compoud. It should be noted I am not runing any liquid cooling setup like gamers often employ on their machines; just a CPU fan and two chassis fans pushing/pulling air.But during 'normal load' operation I have seen an improvement of temps being about 6 to 8 degrees lower than before. So that is a welcome result. As with all things your mileage may vary. And definitely put the pad in the frig just prior to application for easier install and removal of the plastic sheeting.
