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.
First time using a thermal pad like this? Check out our quick installation guide here
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.

Size Guide










Knocked an easy 5–8 degrees off my CPU temps after only one day burn in. Cinebench went from a before of 1928, to an after of 1970 to 2024 the next day.
Tip: Put in freezer for 15–20 minutes before using, cut to size, peel the stiffer side off, apply to CPU, take an ice cube in a plastic bag and put it on the top for 30–45 seconds. It will harden the PTM and make it easier to remove the plastic top protector. No bubbles, no tears in the PTM.
I have a minisforum BD790i and it was running at 93° playing arc raiders. I switched the thermal paste out for this stuff and my temps immediately went down to 75° playing that game.
I’m not saying everyone will see that much of an improvement but it certainly will improve your performance a bit
The temperature is really good now. The only issue was the phase change material changed phase during shipment and was thinned flat on the plastic cover
I bought the bug pads for my DL380 gen10 server, as several others mentioned the material would not come off the plastic sheet for anything, i peeled and scraped and eventually was able to cover the cpus with the thermal pad material.
It seems to work fine, but no better than the thermal paste I had on before, and not worth the hassle at all.
You know there was nothing to write home about but nothing to complain about and I’m all about that. I wasn’t expecting a crazy 2 day delivery but what I was expecting was ltt quality and I got that through no hiccups in ordering and good quality product. Good job
