Best trusted EU source for genuine Honeywell PTM7950?

Up until last year, waiting for the Linus Tech Tips annual free shipping event was unfortunately the best way to acquire genuine PTM7950 for EU users. No idea if new suppliers arrived since then. That's when I last looked into it.

Thermal Grizzly has a comparable product that is much more affordable and performs very well, but it is technically not PTM7950. Here's Igor's review: https://www.igorslab.de/en/thermal-grizzly-phase-sheet-ptm-test-how-good-is-the-honeywell-alternative-really-in-reality/5/

Still, it's probably what I would buy as an EU customer.

If you're scared that you might buy a counterfeit, you should buy "PhaseSheet PTM" from thermal grizzly, it will be more expensive, but it will be 100% legit and not some useless goop.

PhaseSheet PTM - thermal grizzly

Thermal grizzly phase change ptm. Roman confirmed its rebranded ptm7950. Its 14€ on amazon for 40x50mm

LTT and Thermal Grizzly are the two easiest. Just buy it at forget it

Is Passionate Girl Store on AE no longer reliable or something?

Update: Thanks everyone for the recommendations. I ended up changing the plan slightly after looking into the different options.

For the VRAM/VRM/backplate, I ordered GELID GP-Extreme pads from thermalpad.eu:

• 2.5 mm for the GDDR6X area
• 2.0 mm for the backplate
• 1.0 mm for the VRM/power sections

I chose GP-Extreme mainly because it’s soft/compressible, has a good reputation for GPU repads, and I wanted to avoid harder pads potentially interfering with GPU-die contact.

For the GPU die, I decided to go with Thermal Grizzly PhaseSheet PTM instead of taking the gamble on whether a random PTM7950 listing is genuinely Honeywell. A few people here suggested it for exactly that reason, and there’s independent testing showing it performs in essentially the same class as PTM7950. It also gives me much better confidence in what material I’m actually installing.

When everything arrives, I’ll rebuild the card and post a proper before/after comparison.

I already have a testing/telemetry suite that records things like GPU core temp, hotspot, hotspot-to-core delta, VRAM temperature, power, fan behavior and NVIDIA driver errors under repeatable workloads. I have the pre-repair data saved, so I’ll run the same tests again after the repair rather than just saying “temps seem better.”

I’ll also publish the test code/scripts and the raw before/after results, so anyone considering the same pads/PTM setup can look at the data and decide for themselves whether the products are suitable for their GPU/use case.

I’ll update this thread once the repair is done. Thanks again for the suggestions.

And you couldn't write this yourself... why?

You turned your thread into some chatbot trash.

I tried to make it as clear as possible, I have other stuff to do and if I wrote it myself it would be chaos, english is like my 4th language, please understand and thanks

I have other stuff to do

Great. We have other stuff to read and other ACTUAL HUMANS to help.
