Where to find PTM7950 paste?

Kucing · 2025-03-16T11:10:39+0000

A lot of people saying that there are many fake PTM7950s. I am looking for the paste not the pads so it's even harder to find anything. I found this on ebay but no reviews of the item (just of seller) and come from china. So,anyone can suggest me a source to buy legit ptm7950 paste ?

According to Igor's Lab the pad is a lot better than the paste.

Engrish translation aside:
Basically, the paste version is not as good (likely from cold viscosity limiting bondline thinness)
and (being PTM) quasi-solidifies into something glue-like, regarding removal. [The thin sheet PTM seems to limit the mechanical bonding strength, better]

Personally, I'd imagine setting the (sealed) tube of PTM paste into some hot/near-boiling water, allowing it to 'heatsoak'
might make the application easier, and with a thinner bondline (improving performance).
I wouldn't consider doing this with 'traditional' pastes, as they're a suspension. PTM is a Phase Change Material, it *shouldn't* separate, short of active chemical attack.

Regardless, Igor mentioned it's easier to apply and more-useful for especially topographically-mismatched thermal bonds.

Wow, good to know. I thought that pads are always worse than paste. Is this just an exception?

I bought from there and did indeed get the genuine stuff. Shipping is a bit harsh to the USA, but YMMV. I just threw some other articles in there to make it "worthwhile."

Have you done many applications with it? How 'bad' is it to apply? Does warming it up help?

I'm (usually) too unsteady to apply cut PTM patches. A paste ver. of the stuff is very attractive.

I didn't buy the paste version. For the pad version though its the opposite, 15 mins in the freezer massively aids in making the application doable.

It is very sticky clingy and prone to breakage, unlike normal thermal pads. The freezer seems to lessen this enough to make it "average" difficulty. Without that trick I might even call the application "hard."

I've done three applications total (once on my cpu and 2x gpus, a 6900 XT and a 7900XTX).

I can relate as I'm fairly disabled in one arm (nerve issues from a bad bone break cause random spasms). But I manage it if I do the freezer trick so it must not be awful.

I've done this 'trick' the 3 or 4 times I've (attempted to) apply the stuff. It certainly 'helps' but if you're not quick and/or you have high ambients, the 'help' is EXTREMELY short-lived.

Unironically, encouraging.

Next time I try to use the sheet, I'll leave it in longer, and try to prop the sheet atop a cold pack (to give me a little working time to coordinate myself :laugh:

)

To be fair my freezer is known to be on the cold side. It seems to be well below what most normally operate at for some reason so maybe add some minutes yeah.

Also, TBF
That sub-mm sheet is purposefully thermally conductive and of near-zilch thermal mass :laugh:

Get it now! The PhaseSheet PTM is a thermal pad based on a phase change material (PCM). The pads, which are solid at room temperature, can be easily applied and liquefy during operation, allowing them to effectively dissipate heat like a thermal paste.

I can only advise here, if we talk CPU usage, to try going for Thermalright Heilos pads. Those are ones that I can vouch for and have good reviews (ie they perform on par with HW PTM) and the benefit there is that they come pre-cut in the correct size for either AMD or Intel, depending on the SKU.

If you're from the EU i recommend a Thermal Grizzly Kryoaheet, easy to get and cheaper than importing a TPM.

Using a Kryosheet on both my 4070 Ti and Intel NUC.

Just make sure you have some kapton tape as well to cover SMD's, i did that on my 4070 Ti.
