Would PTM7950 suitable for motherboard PCH?
Edit: Actually, I just remembered I've got CX H1300 if that's a better option
Update: Okay guys it seems like PTM7950 isn't suitable for that, thanks :)
Heya guys, I've got an MSI Z790 Tomahawk DDR5 that I'm giving to a friend, in the past, just for pure experimentation's sake (too much free time) and boredom I removed the PCH heatsink and replaced it with thermal paste - that was like 2 years ago, and haven't used motherboard much since then. I was wondering if PTM7950 would be a better (even if it's a marginal difference) option? I just want peace of mind for him before giving him the motherboard because I don't even remember which thermal paste was used. Don't get me wrong, obviously I have zero concerns handing it as it is, this is just the OCD hobbyist in me asking on this matter.
Added some pictures from when the PCH heatsink was originally removed and is shown is the original cooling material. Any idea which stuff is used at the factory? I remember it feels like very firm rubber, it wasn't easy to remove from what I recall.
Cheers.

Thanks bro xD I've got CX-H1300 which I never even tried, and I heard it's not easy to apply but I'll do my best.
Just wondering did it improve the the PCH tempe for you with putty? For me after I tried from the factory material to thermal paste it was pretty much the same temps if I recall correctly. The temps weren't even high at all for PCH I was simply bored and wanted to experiment lol. Fix it till it's broken as they say.

Using upsiren utp-8 on my x870e apex. Temps improved by 15c.
Stock thermal pad was like Plastic and had heat transfer like a walnut.

Wowzy that's a huge improvement. I lold at the walnut transfer. The stock material here also seemed like plastic lol. Just one last question since this gonna be my first application, did you make a ball shape over the PCH and then tighten the heatsink or try to spread it across the PCH. Thanks.

Ball shape and squeeze it with heatsink. Putty is really easy to use and forgiving. Spreads perfectly under pressure.

just use a thermal pad
phase changer could be very thin

Yeah, that's exactly why I wasn't sure about, I've got some Gelid Ultimate 0.5mm, nothing else tho.

No the chipset does not get sustainably hot enough to melt the pad
