Thermal Grizzly Presents PhaseSheet PTM Thermal Pad
With the PhaseSheet PTM, Thermal Grizzly Holding GmbH presents an electrically non-conductive thermal pad based on a phase change material (PCM). With PhaseSheet PTM, Thermal Grizzly closes the gap between traditional thermal paste and thermal pads based on graphene or carbon thermal pads. This means that the respective advantages in terms of application and thermal conductivity can be combined in one product.
PhaseSheet PTM is a thermal pad that has been optimized for applications where maintenance cycles are subject to long intervals. It is more durable than traditional thermal conductive pastes, but not as durable as KryoSheet, for example, which is virtually maintenance-free. The maximum thermal conductivity of PhaseSheet PTM develops and stabilizes after around ten thermal cycles above 60 degrees Celsius.
Compared to traditional thermal paste, PhaseSheet PTM retains a very low viscosity in its liquid state and contracts again when it changes to a solid, so that the so-called "pump-out" effect is only very slight. With the pump-out effect, the thermal paste is pressed out over time, for example between the heat spreader and the base plate of the CPU cooler.
Applications for the PhaseSheet PTM include replacing the thermal paste on older graphics cards or converting to water cooling. Notebooks also benefit greatly from PhaseSheet PTM due to their cooler design and the thermal pad can also be used between processors and CPU coolers.

Yes, on low loads it’s worse, but it’s normal, as per TPU test. Still, miles better than paste.
They write: "While there are some standardised methods for testing the thermal conductivity or thermal resistance of thermal compounds", and then put a comma, say one big BUT, and continue with some type of nonsense.

Plus the fact W/m.K can be measured in any situation and is very easy to manipulate as a stat.
"Hello John,
thank you for the message.
The thermal conductivity values, which are usually determined theoretically, vary greatly depending on the application, as important factors such as contact pressure, temperature or surface cannot be taken into account uniformly.
Since the 4th quarter of 2020, all our cooling products therefore no longer provide specific values for thermal conductivity.
We continue to rely on the test results of independent tests and reviews so that our customers can get a more realistic impression of the performance of our products in practice under comparable circumstances.
We wish you a pleasant start to the week."
W/m-K is a scientific formula and can be reliably repeated under test conditions, therefore I say they SHOULD show that rating on their product, regardless of the end users outcome.
Next Auto makers will remove their fuel consumption tests and rating on new cars using the same excuse, as the testing can be variable etc. :kookoo: :roll::roll::roll:
I don't suppose you take dBA and CFM numbers for fans at face value too?
didn’t do the chill or freeze method but just went ahead and tried the install. You only yolo once as kids would say.
effortless install. So if you suck like I do and want to ptm or close enough to it, this would be the one to get.
Fwiw the texture seemed less clay like than the supposed ptm7950 I had purchased from Amazon. That Amazon ptm was mx6 levels of good so we will see how this turns out.
