Thermal Grizzly - PhaseSheet PTM (50x40mm)- High Performance Thermal pad with Phase Change Material | Durable, not electrically Conductive | for CPU, GPU & Electronics Cooling

Favorable temperatures relative to paste when applied to my 7950X (16C/32T) -- attached image is result following a 30 minute compile job. Cooling solution is ThermalRight Peerless Assassin (dual tower air cooler).Temps are a little better than paste and a little worse than liquid metal. No risk of destroying your equipment like with liquid metal. Reusable unlike paste. A little annoying to apply, but not as bad as liquid metal. Like liquid metal, performance does not degrade over time and requires little or zero maintenance.Ultimately, the cooling solution itself will be far more impactful than the choice of thermal interface material.It has a few quirks of it's own. The slab of material is probably a little too thick. Anyone who has worked with LM knows that less is more and too much worsens thermal performance. I suspect the same is true here as well, but because the material is solid at room temperature there isn't a good way to apply less. Checking to see that everything is good is kind of a pain, because the material needs to go through multiple heating/cooling cycles before temperatures become stable. When leaving idle, temperatures will ramp to around 55C almost instantly while the material is changing phase before coming back down. Obviously this isn't an issue in terms of hardware safety, but it cause some intermittent weirdness with acoustics where fans will aggressively ramp up and then instantly back off unless you tune your fan curve to account for this behavior.All up, I really like it. It manages to keep most of the advantages while eliminating most of the disadvantages of each. No maintenance and no risk of destroying components is great quality of life. No solution is perfect and every solution has tradeoffs.I'll probably use this TIM in most of my future builds.

This stuff works great, I bought this for my laptop because the Arctic MX-6 paste I have been using rapidly degrades in performance. The initial performance is amazing, but it takes only about a month for it to cool like some old dried out paste that was five years old or something. This product keeps my laptop almost as cool while gaming, but is expected to maintain that performance for a very long time. I had no issues at all installing it for the first time, I suggest reading and following the instructions that are provided for best results. The only thing I wish I had done differently was to have a micrometer to measure the CPU and GPU die size instead of just eyeballing it, and to have a sharper set of scissors to cut the pad down.

Is this stuff bleeding edge technology that will result in the lowest temperatures you could possibly get? Unlikely, but it does perform great, its longevity is unmatched, and by buying it you get to support people that actually care their customers and the industry as a whole.

Application was annoying, I put it in the fridge like all tips have said, it really doesn't want to be applied. The red plastic lip made it even harder to apply. PTM should really be used on direct die applications, I used it on my 3060.Temps were the same as the thermal paste when at stressing it on furmark. I did cycle it a few times. At idle the temps were cooler than before by 13 - 15c. It does work, I guess my cooler doesn't have headroom to take advantage of PTM.

This works better than paste and as well as kryosheet (graphene pad) but without electrical conductivity. NO kapton tape needed. All you need is this and a scissors. Put it in the fridge for 20 minutes or freezer for 10 minutes. It gains a rubber like consistency where u can cut it with a scissors to the sizes of the cpu and gpu die, peel off one side, place it on the cpu and gpu then peel off the other side and you're done.Tweezers wont work, you have to use a razor blade or something as thin and flexible to help peel off the plastic on both sides of the material. Place the cooler on, screw it down tight as it will allow. Put the system under full load, and i mean full. What happens is the heat transfer to the laptop's heat sink is increased greatly. The only thing hot to the touch in the laptop at full load is the heat sink, nothing else. As it should be.Max temps on an i7 8750h cpu + gtx 1080 mobile are 67-75 Celsius under load (different games from mmos to first person shooters) and 47-50 degrees idle (just normal web browsing or video watching).Its better than thermal paste, as good as kryosheet. It doesn't dry out like thermal paste because it turns back into a solid when cooled below 40 degrees so u get a good 10 years+ easy without needing to repaste. As it thermal cycles the thermal conductivity gets even better, what it plateaus to i dont know. So far ive cycled about 5 times as of this review and Im getting good temps, can only think it will stay the same or get even lower temps as time passes.Thermal paste is obsolete.EDITAlso applied this on my computer and some computers at work, temp drops are better, FAR better than stock paste or the best thermal paste you can get your hands on. Though it will take more thermal cycling for the results to show, ie 60 or more cycles between room temperature and anything above 60degrees Celsius.The hotter a cpu can get, the less cycles you need. Temperatures stabilized (reached a point where they dont get better or worse) on my home computer faster than it did on the computers at work which use 9th gen i5s compared to 7th gen r5 7600x3d which my desktop uses and is under way more load than the ones at work.Forget the bad reviews talkin about bad application and screw ups, those people have too much lead in their water supply. If you have sense, you KNOW this thing makes thermal paste obsolete or you will come to the realization after trying it yourself.

I have to give the product one star and I hate it, but what came was impossible to use. I don't know if it was heat exposed or some other condition, but could not pull adhesive protective strip without trashing the thermal pad.
