Repairing Broken PCIe PCB lanes with Solder

[gothen1234]

I recently delidded my CPU and stuck a kraken x61 onto it after finding this:

https://hardforum.com/threads/nzxt-kraken-x61-liquid-cooler-direct-die-mount-made-easy.1865797/

the cooler doesn't sit right and no matter how I mount it, CPU cores #0 and #3 have a good 10degree celcius temp difference.

Anyways, I tried remounting the CPU cooler and one of the thumb screws got stuck in the backplate so I had to resort to using a pair of pliers to get it unstuck from the board, this caused some damage and severed 2 of the copper lines that run through the motherboard to the first PCIe x16 slot.

It's an Asrock z97 extreme 6 btw

Now I have to put my main graphics card into the 2nd PCIe x16 slot which means I can't use an m2 ssd with the full bandwidth of PCIe x4 as it would disable the slot the main graphics card is in.

On top of the m2 ssd problem the southbridge also overheats as a result of having the main graphics card being installed in the 2nd slot....

...it's just not viable to have the top slot broken, and have to accept that it is.

So my Question:

Would I be able to solder the PCIe data lines back together without considerable damage to the PCB?

Can you use your cell phone and a desk lamp to get a good clean shot of the 2 damaged lanes? Now me personally I could probably repair it, but if you have never soldered before I would highly advise against it. You could try RMA the board just say the top slot never worked and you want a replacement or repair.

I just took a look at the lanes, it's clear that there is damage, the lanes are less than 0.3mm apart, I don't have the equipment or the expertise to do this.

I would highly advise against it if the solder where to connect it would cause devastating damage upon boot. Maybe if you are able to fit a thin piece of plastic or tin between it while someone (who had the equipment) soldered it would probably be the only way to attempt it.

For the time being, if you plan to continue using the motherboard go out to your local home depot http://www.homedepot.com/
And pick up some liquid electrical tape. Put a dab on the broken lines (DON"T if you plan to RMA the board) to prevent them from touching by electrical static discharge etc..
