What i did was to cut a piece of paper and trim it until it fit my cpu and gpu perfectly then i lined it up on my length of ptm 7950 and cut it exactly so no wastage.
@@SuspiciousKoala It's only a little better for the 5800x3d because the CPU uses an IHS. Best results are from direct-die contact. I use it because it better than Kryonaut regardless. I actually forgot to record the before and after temps. It still works better than any paste on a CPU, but even better on a GPU.
On hot laptops, this is as good as LM, or very close. And it gets BETTER overtime apparently, also needs no replacement every year or so, like Thermal Grizzly paste. I have gained permanent measurable turbo with Ryzen Controller + PTM on an Ideapad S145. Even though it's a 30w chip. Idle temps stayed the same at 46 celsius, but with the PTM (usually 30-40 minutes after turning it on), I can stress test on Prime95, which is the most insane test and it takes SO long for boost to lower. Next step is adding more material to the heatsinks, I will add some more small copper plates along the heatpipe (which is ridiculously small on this laptop). I think this will allow the device to turbo for even longer.
Do you have to keep the PTM7950 in the fridge before cutting and applying? Make sense to use some paper or something to create a template for the CPU that you can use. Worth using tape on the PTM in order to remove the protecting film easier and minimise tearing?
So paste above an IHS makes bugger all difference. Paste under an IHS makes a massive difference as you only have a small contact point and die lapping has even more benefit.
Good question, I don't know if I have the exact knowledge to answer this, but with my personal experience, it actually brought down my temperature from the mid/upper 40's to mid/lower 30's. Truthfully about performance at lower temps I have no idea, but just from the idea that, for me, it keeps it around the mid 30's range idle from the upper 40's seems to be working as it should and if anything performance seems close to the same, maybe slightly better due to that. Key factor for me is longevity and not having to replace it. That probably didn't answer anything and I'm sorry
@@harrisontheeditor Great answer thank you. I think I'll bite the bullet and get some for my iMac which I don't want to have to open up again for another 10 years.
@@edmundmorris3227I'm from Indonesia... I will try to use this PTM 7950 for my macbook pro 2012 md104 . And for the Infinix Note 8 cellphone if there are any advantages😂
I did, my 5600x with Arctic MX-6 hits 74c in cinebench. With PTM it hit 73.6c. As others have mentioned, PTM is best for direct die cooling like GPU or laptop CPU.
It last forever. I put it in an old laptop and after 4 years temps seem to be as good as day 1. Before that after 1 hour of office work fans were running always at full speed but since i put it in, it never goes full speed. You can check Linus review, it' seems it gets better with more use.
@@PtSp86 er no, ptm is actually great when its under high pressure and its not that expensive considering my kryonaut pumps out every 6 months or so.

Did the same
This is EXACTLY what I was looking for. Looking forward to my next CPU upgrade in my mini-ITX system!
Except all annoying bs complaining and crying like a lil girl
I put it on my RTX 4080 and my 5800x3d. Great results on both but the GPU more so because of direct-die cooling.
That's what I've heard as well for GPUs as well! Glad to see someone else is trying it out as well
Before and after temps? Also why is it the small channels are the best ones for cool solutions lol
Would you say the PTM would be better on that 5800X3d than Kryonaut?

what is exactly the temps before and after using the PTM7950 ?
I have PTM7950'ed my DeskMini X300 with a 5700G and i'm very happy with it.
Works very well on my 5900x oced to 4.2 - 4.4ghz at 1.15V+_ on an Assassin III and my RTX3080Ti Aorus Master
Hey, could you please tell how did the temperatures fare?
@@manoftherainshorts9075 68-72c under full load. Room AC Temp at 24c.
@@manoftherainshorts9075 With AC on its about low 60s without AC high 60s on all cores

Yes, its better keep in the fridge before applying, you can use some paper and its better using tape to remove the protecting film. lol
The thing is, I don't know what size I buy, what size is a CPU?
to where I live it, costs the equivalent of 5-8$ depending the the size
So paste above an IHS makes bugger all difference. Paste under an IHS makes a massive difference as you only have a small contact point and die lapping has even more benefit.
How well does this work at lower idle temps on a desktop cpu? Is it only effective above 45°? Or does it still perform well at 30° or so when idle?

I feel your pain with the D15
Really wish you did a temperature comparison running prime95 or cinebench or something

can i use that also for cpu?

Have anyone tried to put ptm7950 under ihs on a delided desktop cpu would it be better/less maintance than liquid metal ?
why is it 20+ min long?
What size did you buy?
I bought the 80mm by 80mm square, only for the reason if I screwed up I could try again.
Why the hell does this have so many dislikes? Wooow
Probably because you can't see anything! 😄
