Pad thermique à changement de phase PTM7950

Works right away. Once it "cooks-in" and all air pockets have dispersed it should exchange heat even better.

The TLDR is that this works, but I wouldn't bother, just use paste.

For more detail: This is precisely what is promises: It is Honeywell PTM7950. It is nicely packaged and it ships fast. Absolutely no issues from a fulfillment point of view, and you can trust it is genuine unlike random sellers on eBay.

It also works fine, my CPU is running with it now and it keeps it under max temperatures, even under an unrealistically heavy load like Prime95. It has no issues cooling my hot and hungry 13900K.

So why the mediocre review? Because it is a pain, and doesn't seem to be any better than a good paste. Application is rather tricky, as many people noted. It's not as easy as Linus makes it look in the video particularly if you've never done it before. It is hard to get the pad to stay and not to have part peel off with the plastic, and hard to get the plastic to start peeling. Putting it in the fridge helps very little as it heats up the moment it touches the CPU die and your fingers (which it would, since it conducts heat well).

I find it much more fiddly than paste to apply. My first application went bad and I had to cut off a new piece and try again. I did get it applied though and then fired up my system. I did a few cycles of "run Prime95 for 10 minutes to heat things up, turn off the system to let it cool down" as recommended to it can undergo its phase changes and get in all the cracks.

...and in the end? Temperatures are basically the same as I had with Arctic Cooling MX-6. Both are fine, no thermal throttling in either case, but if there is any improvement, it is small enough I'm not noticing.

Thus given the fact that it is pretty expensive, and a pain to install, I'd give it a miss and get a good paste, or go liquid metal if you really need good cooling. It just isn't worth the money nor the hassle.

That said if you are determined to get it, I'd buy it here. LTT Store does a great job with fulfillment and this is probably the only merchant I'd trust to have genuine stuff given that too many shops let unregulated 3rd parties sell on them these days.

It's ptm7950, the real stuff, in a large quantity. Exactly want I wanted

To be honest, this is the most awful experience I have ever had when purchasing from a store outside of Colombia. While I just ordered a single product that is just around $20 CAD plus $13 CAD for shipping (thus, any custom fess should not apply since it's under the $200 USD cap), you guys and UPS didn't provide any clarification about why I was being charged with almost $28 CAD to claim my package. No one gave me a clear explanation if this was due to some sort of premium shipping rate, shipping taxes or whatever. UPS didn't provide the invoice related to the order, and when I asked you guys to help me with this, you basically wash your hands of this issue and didn't even try the attempt to ask UPS for the invoice (also UPS didn't help me out to get this invoice). Now the package has been returned to the sender, and my money is lost. At this point, I feel like I've been robbed. I would not EVER encourage anyone from my country or South America to purchase anything from this store. To be fair. I had better experience by purchasing items from random strangers located the US, Canada and Mexico through Ebay than from LTT Store, and I don't want to imagine how this issue would have been far worse if I decided to purchase more items.

Can't really comment, package is still customs hostage
