News Thermal Grizzly's new thermal pad has a phase-changing design — the pad changes from solid to liquid above 113ºF

[Admin]

Thermal Grizzly has introduced a new thermal pad that can change from a solid to a liquid above 113 degrees Fahrenheit (45 degrees Celsius) through a phase-changing material.

I wonder how they compare to the Honeywell PTM7950 Phase Change Thermal Pads which has a thermal conductivity of 8.5 W/m.K

(thermal grizzly doesnt seem to have the specs anywhere on their page)

Der 8auer is his YT channel name, one in German, one in English, he always does a product release video (I havent looked yet) and send it out to reviewers, so I would start there.

If there is no information on their web page, then perhaps someone jumped the gun and this hasn't been launched yet.!

I'd bet it's just PTM7950 cut down from the master sheets and packaged for individual applications.

The Phaseheet PTM requires 300 to 400 newtons (67 to 90 pounds) of pressure to be used optimally with the lowest possible layer thickness (i.e., best performance).

This must be per unit of area, but it doesn't say. Does that mean it's for the entire sheet? I checked the datasheet and it basically says the same thing.

Heh, the datasheet has some words in untranslated German. So, it's possible someone jumped the gun on publishing it. Check out the Downloads tab, here:

I think you’re right. They’re probably cutting PTM7950 into pieces that cost about $2 each and selling them for $11. Small third party companies in the PC niche have been doing so already but they’ve been even higher in price.

AFAIK, PTM7950 is not reusable, where as the phasesheet is.
I wonder if it's also easier to work with. PTM7950 is challenging and even if you are careful, it's easy to accidentally tear.

 

[IDisposable]

I think you mean that upon heating up it changes to a HIGH-viscosity liquid... otherwise it's just going to ooze out.

This is just another ptm7950 clone but with a significant price bump. Just buy a sheet of PCM1 from AliExpress for $8, it performed identically to my ptm7950. Also it doesn't matter if you tear this stuff. One it liquefies it will mesh back together.
