Thermalright Heilos Solid Thermal Interface Sheet, Solid Thermal Conductive Silicone Grease Sheet for CPU/GPU, Conductivity 8.5W/mk, Desktop/Laptops General Purpose,for Intel (30×40×0.2mm)

Performance -Using a 13900k @ 290w with a corsair H115i (280mm radiator) & a thermalright contact frame.Moving from stock corsair thermal paste to this pad decreased cinebench temps from ~93c to ~90c. For thermal paste, a 3c difference is pretty impressive. The 13900k will always run hot, but this pad gives you some extra breathing room.Installation -Not fun. Pad is thin, and strongly adheres to plastic. I froze the pad before installation (less chance of ripping) & used a hair dryer to melt the pad a bit after applying it (to remove second plastic piece). Expect this part to take some time and frustration.Notes -Based on packing materials that mention "phase change temp", I am assuming this is rebranded ptm 7950. Most other ptm 7950 listing cost more, and come with a degree of uncertain authenticity. As thermalright is a legitimate company, this seem to be the cheapest and most reliable way to acquire this type of thermal paste.As to its performance, ptm 7950 is still pretty new in the pc building space, but early adopters report that performance improves over time, with some listing reporting 1000 curing cycles to reach max thermal conductivity. I've only been using the pad for about 2 weeks, so I can't vouch for the long term performance yet.

I bought two of the Intel versions. I applied it to my 13900K, and an EVGA 3090. Both of them had issues with sticking to the plastic, but I just slowed down and remained patient. Even with small tears in the material, you have to remember that once it heats up it'll liquify and join together once again. Both my processor and GPU are covered for a while as this won't suffer pump out. The temps are good immediately after installing, but they will get better with time which is even better. Remember patience is key with this product. I bought two, and used two.

I recently decided to change around coolers on my two cpus and didn't want to worry about getting the exact right amount of thermal paste for each application, these solved that. I don't notice a significant difference in temps between these pads and high end thermal paste so in my opinion that is a win for these with temps being equal and install being much easier. They fit my am5 cpus perfectly and cost way less than some other options for what seems to be genuine ptm7950.

The protective that was supposed to peel off first for installation didn't, other side did instead. However the ambient temp is higher at the moment due to summer.Easy to tear, this was after sticking in the fridge to help prevent the phase change. Next time will put in the freezer.Make sure you have everything ready to go before applying.Overall though, fairly happy with the temps even though installation didn't go as planned. The hotspot on my 3060ti is about 10c-12c higher they the average. Down from about 20c higher.

Completely unusable product. I got two of these and neither one would peel off the clear sheet. It comes off the white sheet fine, but it tears or breaks when trying to get it off the clear sheet. Even if you can get it off, there will be thin spots and some spots where it's thicker because of the breaks and where it pulled. There's no way to get this to actually lay flat. Luckily it's cheap. I ended up throwing them both away after fighting with it for over half an hour.

Same specs as PTM7950. Throw the sheet in the fridge for about 5 minutes. Apply to the heat sink as advised in the instructions. The larger surface area makes the pad adhere easier. Slowly pull the plastic off the pad. Apply pressure after the pad is aligned on the heating. Let it sit for awhile like 10 to 15 minutes. It will make it easier to pull off the plastic without messing up the pad. When applied properly the pad works great. This stuff is way cheaper and just as good as PTM7950. I’ve applied this to a 5950X, 7900X3D, and a 3080TI. All have great temps. You just need to be careful and patient while applying. Again, follow the instructions, lol.

I read somewhere that Thermalright was basically selling PTM7950 at a lower price, and while this may be similar to PTM7950 it's not the same. I'm used to handling and installing PTM7950 but this material is way more brittle and more difficult to apply than what I have already. Took a chance on this for the price and am a bit disappointed that it's not easier to apply. It tears and just refuses to come off of the plastic sheet it is on.

Used it on my GPU die and motherboard chipset dies to bring down temps. GPU had a major difference as I think the thermal paste that came from the factory had started to give/pump out or something. Reduced my temps from very high hot spots on my 7900XTX to reasonable hot spots. Chipset die I'm not sure how much it did but I think the fan on the x570 chipset is a bit more calm now.I did have issues with getting it to stick and come off the plastic but even if it breaks as long as you get everything covered when it heats up it should liquefy and hopefully be ok as long as no air bubbles.
