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.

The packing was really well done, still phases changed a little on the edges but very useable for my laptop or even if I want to put it in in a PC. Thank you!
Easy install, no issues
Application is tricky but watch some videos. Putting it in the fridge is helpful.
Performancewise it's very good. Have achieved around a 5 degree celsius drop in Cinebench
10/10 not much else to say. Keeps a 14th gen intel processor under 65 degrees with a 240mm AIO under 100% load.
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
