2X same Card, different PCBs

[Davidwr80]

Hi,

Not to long ago I made two Posts about my GPU temps and that one GPU is significantly hotter than the other one (in a custom loop).

Since then, I noticed that one of the water blocks does not sit as flush on the card as the other one. I removed both water blocks and took a close look at both cards. Then I noticed, that one row of power components on one card looks different than the other one (see pictures).

 

I measured their hight, one was 2mm (the square ones) high, the other one 3mm (the round ones). Then I measured the space on the EK block where these components go and saw that the standoffs from the block are only 2mm high. That explains why one of my blocks was slightly bent and did not have full contact to the card. I pretty much solved this Problem by removing the thermal pad on the card with the bigger power components and applying thermal paste instead.

But my question is: Why would Gigabyte/Aorus use different power componentry on the exact same model of card (Aorus 1080ti). Since one of my EK blocks fit perfectly and the other one did not, I assume that EK did not know about these differences, and I did not see any warnings about this on their site...

May be a different revision of the same card.

im going to presume it becuase they use different parts and its random on what you get, bit like phones having different memory manufacturs etc, afaik the aurous extreme has only visual compatibility

Yeah, I guess...I just did not think that they would use components with a different hight since that is a problem for full cover water blocks..

Means Same card,different revision.
