My understanding was that ptm 7950 practically speaking lasted for the life of the device but Honeywell only guaranteed the out of device shelf life at about a year, is it being exposed to air that degrades it or does it experience dry out on die like normal paste? Enjoying and appreciating the content!
This is an excellent question. I assume that there is some additive chemical keeping the PTM 'fresh' and possibly this is just Honeywell CYA because I haven't heard of or seen on discords or other channels where any of the PTMs wear out. I tend to agree that any of their PTM products will most likely last several years.
Yes, that is how I did it in the past. Use low speed or low heat, and pulse the heat, like 3 seconds on 1 second off. Be patient. Pre-heating the tube make sure to keep the cap off and keep the nozzle of the tube down towards the cpu/gpu die as it may just start flowing out. When it does get to 45c and turn into liquid put a pea size blob and then keep the heat on. You may need someone else to hold the blow drier at that point, but you want heat all the way until you clamp the heatsink down to the die.
@@ElectricLemur Yeah thats perfect and a good stack with CX-H1300 which I have like 3 tubs of. I have used CX-H1300 on many many cards, it works great. In syringe form it will be very difficult to get it to even push out without warming up the tube with a blow drier. Just reach out if you need any help.
I don't think it would be very easy to get out of the tube. It's possible but I felt like I would break the tube trying to get it out, then spreading it would be difficult. Its not bad stuff but honestly I would buy the sheet of 7950 over either paste 9/10 times. I think it's just that much easier to work with. You can look at Halnziye HY-P16 (which I have not uploaded that video yet, still working on it) which is also a paste based phase change but it acts much more like a typical paste at room temperature. I should have that video out shortly.
@@Vinprvx If you apply heat with a blow dryer you should definitely spread it out even if just a little bit. It does not have to be perfect and if its warm with heat it will spread easily. Even if you don't it just means you will need to run some hot/cold cycles (gaming) through the card and it will settle in.
I would go for Thermalright Helios V2 if you can get it in your country, in the USA we can get a sheet of Helios V2 on amazon for $10. It tests higher, after that I would definitely use the sheet of PTM 7950 and not the tubes, its much easier to install.
I think PCM-1 and the Thermal Grizzly phase change sheet will probably all work and perform around the same levels. But I have not tested these products yet. The benefit from the PTM/PCM etc... sheets is that when it melts it forms an extremely thin bond between the surfaces. This means very low thermal resistance and more heat gets into the cooler faster.
@@The_Thermal_Channel I just ordered the PCM1 and PMT from Alie, let's see how they fair. Not that I am a big tester, will just re-apply on two old builds. And only because I want to change the coolers on them.
@@DragonXDrei Easiest thing you can do, cut it to size, just a hair smaller than the die/IHS. slap your heatsink on there. Hit it with a blow drier, 5 seconds on, 2 seconds off for a good minute to heat up the cooler/cpu. Make sure the screws are snugged up again and you should be good to go with little to no break in period. Let me know how it works out no matter how you install it. I like to hear the peoples different experiences on these more exotic products.

Just got the paste from ebuy7 this morning but I don't have a hot air station, can i use a hair dryer?

@@The_Thermal_Channel mine came in a syringe w but will try. I'm want to repaste a mobile 2080 and plan to use CXH 1300 for the VRAM and VRMs

@@The_Thermal_Channel I have a baby milk warmer, can I put the syringe in that to warm it up?
What happens if i dont heat the ptm 7958 paste up?

@@The_Thermal_Channel Ah, thanks! Should I spread it myself or just apply a pea-sized amount or a bit larger and then finish it off?

So normal 7950 or 7950-sp or 7958-sp for laptop :3

@@The_Thermal_Channel nice one, thanks for the info. Will have to see which one arrives first:)
AI rulez!
It is definitely a passion of mine.
