can this small scratch be cause of death of my gpu?

[humblecu]

so i started watercooling my gpu (linustechtips. com/main/topic/905617-did-my-first-gpu-liquid-cooling-diy-style-now-questions/?tab=comments#comment-11137577) everything was fine until i started not being satisfied with my 65 degree temp so i decided to cut the zip ties holding the pump on the die, reapply the thermal paste and make the zip ties tighter so that pump sits tighter on the gpu die, i managed to put this scratch on the card and it stopped working after that, monitor doesn't display anything and backplate where die is doesn't get hot at all. mobo doesn't beep and basically nothing happens.

monitor and mobo are fine, i did try the card in another slot and still nothing. do you think it died that easily? 

[iamdarkyoshi]

I don't think a small scrach like that would stop even the voltage regulators from running...

Its hard to tell if the traces have been cut through though. Can you wipe the area with a tiny dab of WD-40? It might help clear up the area and show the traces better.

a closer image would help more , from a quick look , there seems to be traces there so yes that could(did) kill your gpu from the sounds

[r4tch3t]

Damn, yep. You killed it. If you know an electronics wizard you might be able to fix it. 

[Jurrunio]

increasing mounting pressure wont increase performance once it's sufficiently tight, mind you.

[TheRandomness]

Considering those are memory traces that you probably cut, yeah, it's most likely dead from that.

[humblecu]

i did cut through tracers, it's very clear under sun light. damn dude i loved this card. well it is what it is, thanks for the replies.

i know, the pump would easily slide, i was trying to make it sit a little bit more tight.

Scrape off the solder mask and solder the traces back together. Alternatively, draw a line with liquid metal thermal paste, the smallest amount you can.

Do not used liquid metal for this type of stuff.  Solder is easy to fix this with.

 

LM thermal paste creates an amalgam with most metals and will destroy solder if it comes in contact with it.

However, there's no solder anywhere near the scratch at the scale of this little issue. Soldering individual traces might be quite hard, and he shouldn't use a wire since the length of the trace needs to be preserved in order for the memory system to work properly.

And if it ends up under the GPU from getting knocked around during installation.  Wonder how that would end up.

 

Soldering small traces is very easy, it will bead itself onto the individual traces if you use flux.

He wouldn't have to use much liquid metal at all, and due to its cohesion it should stay in place even if he shakes it about. It forms a conductive oxide if left out long enough, which (if he uses a very small amount and then pulls away all of the liquid) should stay.

Of course soldering is going to be more reliable in the long run, but it's easier to apply and potentially cheaper since you'd need a small tip and soldering iron and solder. Though both require the solder mask to be scratched off.

You dont need a small tip.  You could do it with a huge wedge tip.

 

You just have to use a lot of flux.

A small tip would be more precise, though. And considering the traces are less than half a millimeter apart, I think it'd be a better idea to use a smaller tip.

Because you dont know how to solder.

 

The easiest method involves no tip at all.

Pretty easy fix considering the prices on GPUs now.

[This kid builds pc]

ahhhh you fucked up

[humblecu]

too late to try anything, i disassembled my PC a while ago and sold everything even my 1080ti so i don't have access to a PC right now, i'm going to be super busy finishing college then doing my mandatory army service after that, even if i wanted to do anything for this card that scratch is too tiny to solder for me, what are the chances of messing it up further?
