Dnes jsem se pustil do sapphire rx480, Všude jsem dal na paměti i VRM 1mm termo pad od articu. Je to úplně v poho i na VRM, ona je mekkčí než originál ty černy pady, takže nebyl problém dat všude 1mm. Provedl jsem i důkladnou očistu desky v isopraponolu, pořadně i vyčistil chladìč. Hned mám z ní dobrej pocit. Byla z bazaru za 1600,- tak člověk musel mít jistou a dopřát ji udržbu, aby měl člověk pěkné spaní. Muj 12 let starý i7 3770, je zas schopen střihat videa a být svižný jak za mlada :)

What thickness thermal pad is placed on VRAM processors and what conductivity W/mK ? I don't put thermal paste on the main GPU.

[@z.zabojnik]

It cannot be used on gpu. 6W/mK. See video description.

[@Bukovskyy]

@@z.zabojnik Ok. Razumem. A koja ne debljina termalne pad ? 0.5, 1... ?

[@z.zabojnik]

@@Bukovskyy VRAM 1mm 8:33, VRM 0,5mm 8:55

@@z.zabojnik Thank you (-:

[@Bukovskyy]

@@z.zabojnik Do you know if the thickness is the same for the Sapphire RX 480 Nitro + 8GB

Hey bro try to put hy510 thermal pastr on saphire rx470 gpu so its good or bad?

[@z.zabojnik]

Anything better than the old one. But HY510 has a low thermal conductivity of only 1.93 W/m-K...Just try if you don't have different options.

I use Cooler Master paste, the temperature drops to 65 and after playing two or three weeks it returns to 82, what is the reason please🥰

[@z.zabojnik]

This will probably be the problem that Phenos wrote about. Very liquid thermal paste (viscosity).

[@pcgames3179]

How is the solution please

[@z.zabojnik]

@@pcgames3179 Use Honeywell PTM7950

[@pcgames3179]

@@z.zabojnik Thank you, but Cooler Master paste, there is no way to benefit from it?

[@z.zabojnik]

@@pcgames3179 Sorry, I have no practical experience with this paste.

Nicely done, i watched the vid without translation subtitles so it was vision only. After repasting 100's of devices i recommend higher viscosity thermal paste with manual spread which might be a bit difficult if not used before because an high viscosity paste with the otherwise optimal X pattern might not fully cover a large chip area when placing the heatsink, dry corner. Low viscosity paste has a high risk of thermal pump-out effect on high temperature 80'C+ direct-die devices. (Thick paste is a good thing on hot GPU's/gaming consoles and that's why manufacturers use it for better long term stability (Shin-Etsu X23-7921-5 industrial paste, IC-Diamond (hard to find nowadays and might give little scratches on the surfaces), Thermalright TFX, Arctic Ceramique 2, the good old Arctic Silver 5, Prolimatech PK-3, lasts longer). And if you want a very long stable high temperature drop with minimal pump-out effect i recommend the Honeywell PTM7950 Phase change preformed thermal paste sheet, as a repair shop i switched to huge sheets of this material bought from ebuy7. google "PTM7950 legion 5 reddit". In the past i used MX-4/kryonaut and other easy to spread pastes on laptops and cards but on modern high base temperature direct-die devices (especially 80+'c), the temperature becomes higher after a couple of weeks and those pastes degrade quickly and sometimes fully pumps out to the edges with a puddle of separated silicones left on the chip, uniformity/flatness/contact pressure on the die and coldplate also plays a role for paste stability. On desktp CPU's those pastes are fine.

Thanks for the comment and advice. This is the first card I've ever pasted. I have an RX 470 as a backup gpu. My main gpu is on claim. I also wanted the best for the RX 470, which I know run in the rig (I bought it at an auction). I usually own the cards for 3 years and then change them, so I usually don't need to change the new thermal paste and pads because they are always fine after 3 years :-). Thanks again for the advice, they will certainly come in handy in the future (the biggest problem was finding a suitable thermal pad).
