Description
At long last, the legendary Honeywell PTM7950 Phase Change Thermal Pads from this video are available on lttstore!
If you're looking for a thermal interface material that offers higher performance than standard paste, but you don't want to go through the trouble of something like liquid metal, this is a fantastic middle ground for any PC or DIY server installation. Many laptop manufacturers also go for a thermal pad rather than paste on CPU & GPU installs, so if your older laptop needs a refresh we've got you covered.
PTM7950 sources tend to be overpriced or unreliable in most cases, so we're super proud to offer an affordable, trusted source for this unique thermal material.

IMPORTANT NOTES:
Your thermal pad may undergo one or more phase changes during shipping, resulting in it arriving in a slightly deformed state. This is normal and will not result in performance issues of any kind after installation -- your heatsink will ensure even coverage.
In the event of any leakage from the product packaging, please contact customer support.
Unfortunately we cannot accept returns for thermal pads with open product packaging.

I've been a subscriber of LTT channels since he was reviewing motherboards on a park bench, never had a chance to contribute to him personally, I finally got a chance to purchase a few items from his store now, I ordered this thermal pad after seeing Linus's secret shopper video and knowing the package may come damaged or the product may be affected by the heat but none of that happened to me personally.
I applied the pad to 2 home servers that I use as an actual office server here and noticed a few degrees temp drops.
I still have enough to replace these or to add to other pcs I may have.
Watch his video to know what may happen and to know they are ready to replace the items if there is issue with it but for me this was a smooth transaction from other side of the world.
Great team, Great shop
Good luck to all of you
Applying the thing took several tries on my part and was a bit of hassle to get it right. I use this in a laptop so I needed actually a very small piece, however, I got the large pad. Looking at it, I think I've a lifetime supply for all the devices I'll ever need. Stress testing with Cinebench and Furmark at the same time shows a couple of degrees improvement over my previous paste (Gelid Extreme), so that's excellent results. I need to check again in a year to see if there is degradation as consistency and reliability is the reason why I am trying it rather than performance - normal paste degrades over time in my experience and I need to repaste every year or so. Hopefully this will not be necessary going forward.
Though a bit tricky to apply, even when stored in the fridge for a couple weeks waiting for my Ryzen 9 9950X, I cannot deny my AIOs performance with this thermal pad. The only issue I had was getting the plastic backing off the PTM7950 after applying it to the CPU. It was hard to get it to start to peel at first and then the PTM7950 wanted to separate. I consider these minor problems however and cannot in good conscience deduct any stars for this. Five stars it gets because my 9950X runs cool even at prolonged periods of 100% CPU usage with a 360mm AIO.
Works really better than any thermal paste i tried on my bent laptop motherboard/heat sink. Some hot spots still persist, but total temperature fell down up to 10-15 degrees.
Application is a nightmare, especially when trying to peal off the hard plastic cover (the base) - it just tears all the thermal compound all the time.
Arrived quickly and safely and worked much better giving me 3-5 degree cooler temps on 9800x3d out of the box.
