PTM 7950 mounted vertically

[cookie_machine]

With this being a phase-change material, are there any issues with using this thermal solution in a typical build where the cpu is a vertical position? I've never used liquid metal, so I just wanted to make sure that this stuff isn't going to ooze downward after multiple thermal cycles. I've seen plenty of posts about GPUs and laptops, but I'm still curious what other user's experiences have been using this in a standard tower. Thanks.

Rereading what I posted, I want to reassure you that I know this isn't liquid metal. I was more referring to the viscous nature of liquid metal, but anyway.

It definitely works when the CPU / Motherboard is mounted vertical

If it didn't it would be quite terrible as 99% of all motherboards are vertical mounted.

I got multiple machines, laptop and desktop with PTM7950. All of which is in that situation. Performance doesnt seem to degrade as much as thermal paste even when its applied on an IHS.

Where do you buy it?

I bought mine from the OG ebuy7 link they had in the video.

Please share. AFAIK, LTT's price is very competitive, but who knows?

PTM7950, and other Phase Change Materials, are perfectly fine in vertical position. What tends to heppen is that it melts under load (around 45 Celcius) and then flows out to the edges of the IHS where it solidifies. It'll stay there until you pull the cooler off again, although you shouldn't need to for a long time.

One thing I will mention is that it's good to do a burn-in to get a good melt after you apply it. It can melt down to 0.038mm or 0.0015" in thickness. This means that if yoiu fully covered an IHS then 80% will flow out. It actually works really well if you undercut it with a ~3mm border around all 4 sides so that it is smaller than the IHS itself. Then you just peel the first plastric off, lay down on IHA and rub your finger on the top plastic film to press it onto the IHA and make sure it will stick in place, then either use tape or tweezers to peel top film, and install cooler.

Places you can find PTM7950 include Moddiy, Aliexpress, Ebuy7, and Ebay

ModMyMod, too. Thanks!
