PTM7950 anyone tried it?

[Intox]

Anyone on here tried PTM7950 ?
It's a thermally conductive Phase Change Material for those who haven't heard of it.
Saw quite a few reports on reddit with people claiming it helps reduce the hotspot delta on their GPUs.

Planning to try it later today on my RX 6800 non XT , everyone says it's a giant pain in the ass to install, not exactly looking forward to that.
Will see if the stuff I got is legit, can always remove it and go back to paste if it's crap.

Currently I have Aeronaut on my GPU which I did about a month ago, so my current paste isn't that old.
Anyways will report back when it's done.

Where did you get it?

From Temu
Wasn't going to pay MODDIY prices, I know that MODDIY sells the legit Honeywell stuff but damn they are expensive, so I am rolling the dice on some from China instead.
If it's fake and crap I can always clean it off and apply some fresh Aeronaut.

Assuming it doesn't superglue your die to your coldplate, that is.

Well people seem to be getting mixed results from what Ive seen. It looks like the difficulty seems to not to be in simply applying it but rather in applying it properly. It looks really easy to trap air bubbles. Its a pad but its not porous.

Jup the pad is extremely thin and sandwiched between 2 plastic layers.
The easiest way seems to be, cool the pad first, remove first plastic layer then using included stickers to position on top of DIE then apply it.

Well going to do it now so let's see what happens

 

[Raatle]

@Intox Just try and place it on the die progressively like you putting a sticker on a car. A video I watched where he had bad results he simply placed it on the die and then pushed down it. Careful removing the second plastic layer. Seems very fragile..

Yeah, it can be quite difficult to get off when cold (assuming it's really Honeywell PTM7950, and not fake - the fake stuff is not that difficult to get off). I have used it before. I did not find it difficult to install, just treat it like a sticker.

 

[Intox]

Okay all done.

Thanks I did this and getting it on was pretty good , I left a bit extra on the sides when I did the cut to make sure there won't be any uncovered area at the edge of the DIE.

It was an absolute nightmare getting the top layer of plastic off without tearing the pad but I got it in the end.

Test Results

Before with aeronaut
GPU temp = 62c
Hotspot = 85c
Fan Speed = 2642 RPM
Power = 199W

After with PTM7950
GPU temp = 59c
Hotspot = 77c
Fan speed = 2045 RPM
Power = 199W

So whether this is fake stuff or not it definitely reduced my hotspot temps.
I am actually pretty impressed with the results.

EDIT : ill update with more results after 15 mins of burn in

Update after letting GPU run for 20mins
GPU Temp = 60c
Hotspot = 77c
Fan speed = 2108 RPM
Power = 199W

The temp and hotspot reading varies by about 1c up and down as the test runs

Very nice.. Thats a big reduction for the hot spot temperatures.. How much did this cost you? Turn the fan up to 2600 so we can compare apples to apples..

When I bought it was R89 for a 40x40mm pad
Now I see it's R99
EDIT : Remember you will have to pay customs and vat to Buffalo couriers before delivery happens, on my order it was just 15% vat I had to pay extra

With fan speed @ 2631 RPM
GPU Temp = 58c ( mostly at 58c sometimes bounces to 57c)
Hotspot = 75c (Bounces between 74c - 75c)

How long did derivery take?

I ordered on the 8th of Feb and it was delivered on 17th Feb
I did have to pay 15% vat to Buffalo Couriers for my order to clear customs.

Ordered mine now. I wanna try it out on a 4080 xD just to see... for science!

haha definitely curious to see how it works on that beast.

I've used it on a laptop before, my experience was that it was decent but not much of a difference. I think a desktop gpu isn't worth using over hydronaught.

Incidentally, on the laptop (3070ti and 12700h) using it on the gpu(gpu was regular paste and cpu was Alienware's element 31) resulted in higher cpu temps and reduced performance.
I think because the cooler is shared across gpu and cpu, and the gpu uses most of the power, and it can run hotter(was like 90c with regular paste) that the increased thermal transfer meant that the cooler couldn't cool the cpu as well as it used to. It was slight, but measurable.

Using it on the cpu was as good a using element 31(though or was a year old element 31), but not as good as conductonaught. But if course it lasts way longer.

In the end, if my laptop uses thermal paste on the cpu, I'd replace it with ptm7950. If the laptop gpu uses paste and gpu gets hot, I'd probably use ptm there as well.
But I wouldn't bother on desktop, hydronaught is still better.

BTW you can freeze it and it's easier to deal with, makes installation easier(though to be honest it wasn't too bad before)

I think I'm going to try this exactly because it's supposed to be long lasting, my laptop has needed re-pasting for a while now and stripping an Alienware is a #$@%&! mother of a job.

Speaking to Temu has anyone tried the thermal pads they sell? Thermal pads bought literally anywhere else are stupidly expensive.
