RX Vega64 Thermal Pads

[mare92]

Does anyone know thickness of thermal pads used for Vega 64 Sapphire Limited Edition? From what I saw it varies a lot, but nothing found on this specific GPU.

Since thermal pads are like foam and are very flexible and malleable the thickness doesn't really matter. From what I have see it looks like if you get something like this (https://www.amazon.com/ARCTIC-Compound-Efficient-Conductivity-Handling/dp/B00UYTT3I2) with a 0.5mm thickness it should work just fine.

The blower or the nitro+? Special edition or not doesnt matter, what matters is the cooler.

that's just like saying thermal paste application doesn't matter because paste is supposed to fill up all gaps, no. Graphics cards typically use 1mm ot 2mm thick pads and thinner pads leads to low mounting pressure or even lack of contact.

Maybe the best solution is just to take it apart and try to figure it out (which doubt i can see the thickness from that). Or buy 1 - 1.25 - 1.5 and play with it which I'm not to comfortable with, especially if i mess something up in these hard times finding new gpu...

 

I saw reassembling same card but LC, it was very detailed, it used from 0.5 to 1.5mm pads but I don't know how different is LC and my Air one.

Was hoping and still hope that someone did it here on the exact card and could post his/hers experience.

Just saw question sorry about that. It's blower.

 

And from my previous post, seems that "detailed post" i've saw means nothing right?

If it's the reference blower card, the brand doesn't matter since it will be the same.

Thanks for update!

So long story short i'll just go by this guide and post results.

 

Current problem: 

- GPU temp: 84c

- Mem temp: 92c (prolly would go higher if i let it longer on stress test 1-2c+)

 

One more question though: VDDC VR and MVDD VR are around 58c. Maybe stupid question, are they cooled with pads? If so there is no need to take apart the 2nd layer for pads, just replace paste?

They are either covered by pads or putty (dough like substance). Not sure what you mean by 2nd layer since it:s not recommended to stack pads but you dont have to replace it for the two power rails at this temperature. It is possible to tear thermal pads accidentally when disassembling the card, so this mihht be out of your control.

Oh, by the 2nd layer I meant the additional plate that i need to unscrew in order to reach place where pads are. To be more precise i took screenshot from what I think my card will actually look like when I take it apart. Maybe i'm wrong but i don't need to unscrew everything, if this would be my case (it's the same card and design just different color). You can see from screenshot that pads are actually bellow from what is shown on the picture.

Right then you dont need to unscrew the additional plate nor replace pads underneath.

do not know the thickness. the pads do not have to be the same size but they have to be near the smae size. 0.25mm thicker or lighter.

 

most common thermal pads are either 1mm or 0.5mm so going for 075mm is a safe bet.

 

the blowercooling is likely the problem not the thermalpads.

try replacing the blower with something like arctic accelero xtreme.

After re-pasting and replacing half the pads on mine, I saw no temp difference on the Core and Hotspot temps, but my HBM dropped from 95°c to 85°c.

 

If you get an aftermarket cooler, make sure it cools the VRMs and chokes.

 

For me, personally, I'd rather get a water cooler, but this card was intended to be temporary for me. Though, if it takes 6 months for the 6800XT to become available, I might not have a choice but to go watercooling on mine. =\ My card already drops from 1580 down to 1500ish just to control thermals, and that was during winter time.

So, i've changed paste only without pads. Turns out that design inside is simillar/same to Gigabyte's one - so i didnt needed to remove everything which was good cause didnt needed to change pads.

 

I've used Artcic MX-4 thermal paste.

GPU temps dropped from 82 to 77.

And Memory dropped insanly from 95 to 79 max.

 

It was disaster what paste looked inside. It was all solid, took me a while to clean everything, tbh i dunno how it worked till now.
