Thermal Grizzly PTM Question

[MacWhinny]

Hello, I needed to swap my heatsink that I had installed using Thermal Grizzly PTM and found this. It was flaky in parts and broke off into pieces in others. Is that normal? I thought these could be reused.

It can be reused as in just like standard thermal paste. I mean with standard paste you can scoop the thermal paste on the heatsink and sides and put it back on the IHS.

Whether or not doing so will mess with temp, idk.

Even Kryosheet can tear/break after use, of course PTM can as well.

 

The whole idea of using PTM is to prevent/reduce pump out effect which is... more likely to happen on direct die application.

not about it staying in original shape.

PTM is NOT reusable in the same way that something like kryosheet is. PTM is more like a standard thermal paste in a sheet. It is only in a sheet to make application easier.

You might be disappointed with the temperatures in Kyrosheet, as is has thickness of some 0,5mm. Which is quite a bit larger then 0,05~0,2mm of paste. & having less is better for heat transfer, as physics say.

 

But also, look at the multi-dimensional graph & low data for "extreme OC" for KryoSheet:
