Rx 580 Woes

[trisp]

So i had purchased a gpu from someone (used), when they have sent it to me i have given it the once over and proceeded to open it up and check it and see what needed replacing and so on.

On opening i found the thermal pads were not all in great shape but i had spares so an easy replacement, however i noticed a leaking resistor (i think it is a resistor my knowledge of surface mounted gpu components is nil haha) i did the stupid thing of wiping the leak but the resistor still looks the same, can anyone tell me if it looks like it is about to fail? or if the gpu will die in a firey ball?

It has survived hours of benchmarks since but i am abit cauitous about it tbh.

Spoiler: Damaged Part

Also i do not think his metal tim application was very good... (warning graphic content)

Spoiler: Tim Inside Socket

This is what i saw in the socket when the cooler was first removed it is not very pretty or clean and if i had turned it on it may have caused damage (tim is literally on multiple components bridging connections and there was no liquid tape or conformal coating i could see)

Clearly it was just flooed with metal tim on that side.

Ouch.

The TIM under that lot appears to be non-conductive variety (visually) as you have surmised, but luckily it looks like that is the majority of the gunk on the die itself spread all over. But there's one or two streaks of the Metal TIM that worries me. Not sure how you clean that Metal TIM in that situation (the parts that have streaked over the die on the side) without possibly damaging components. But other than those streaks, the rest should be an easy clearn and repaste job.

Not sure about the burnt/melted component you've shown though. Need someone else with more electronic know-how than I do for that.

How much did you pay it for?

If there's no major issues, I'd probably just refit the Heatsink and Fan setup after a repaste (of whats safely possible to clean and repaste) and just leave it be and just use it until it dies.

Yes cleaning the socket out of all that gunk and metal tim was fun haha

It's a capacitor rather than a resistor. There's nothing inside an SMD capacitor like that to leak out, so it looks more like it's had some extreme heat to deal with and burned/melted. Probably due to a problem caused by the careless idiot who applied that liquid metal. If the card's working fine and you didn't pay too much for it, it's up to you really. Generally caps like that aren't utterly essential to the operation of a card and are just there to provide some smoothing. You never know what effect it might have over time though. If you've got a steady hand and a soldering iron, you could potentially just whip it off and replace it easily enough.
