VRM heatsink for 1070Ti

[hermesa]

I am willing to buy used GTX 1070Ti Gaming 8gb MSI brand ,and I have like 5-6 offers , 2 of them are the regular ones with black VRM heatsink pad and the other 3 are with yellow-ish or gold-like heatsink on this exact part ,I will provide picture...


1st picutre i show the part i am interested in ...
2st and 3rd picture are the yellow based heatsinks or i dunno
and the 4th picture is the black one type which I see on ''unboxing'' videos and everywhere on the internet

My question is , is there are any differences between both types ,and what does it matter , and mostly I need to know If this is a sign (for example the yellow one) for bad quality GPU or manufactoring or bad parts .. Ive heard once that the gold(yellow) parts in PC configurations are the best because they are something like gold and dissolve the heat more effectively.. I dont know if this is the right place to ask but .. just help because tommorow i need to order some gpu ASAP and I don't know which is reliable because all of them are 2nd hand Don't ask me why I am buying this gpu in 2024

I doubt it would make any difference.

I doubt it would make any difference.

I am not interested at all in heat dissipation(+5 or -5 degrees its whatever to me), I am more interested in realiability and quality of manufacture...The yellow one type's offer is not ''opened'' (for changing thermal paste etc. which probablbly means the gpu may have bigger potential for lifespan) and its never touched ,but the black one design seems very trusting manufacturin which is my second offer and is opened one gpu and you can never trust anyone who once touched a gpu and opened it especially here in my country.So I hope someone help by explaining me more detailed what this colours means in manufacturing in gpu's. Searched all the internet for something , but I've found nothing about this ...All of the review's and unboxing videos in internet(pictures,videos) are showing the ''black design'' gpu and I am not sure if its safe to buy this one with the gold plate ...Didn't found even 1 gpu looking like that with the yellow plate on the internet
