S9 capacitor issue with a screw hole

Just got my hands on a used S9 14T antminer and noticed that the backmost of the three 1000uF capacitors under the pci-e sockets is broken and has a screw hole in it. The hole seems to match up with a fan screw, so looks like someone put in a screw that was too long. I've ordered a replacement capacitor that matches the specs (Aluminum polymer 1000U 16V) and I'm gonna try swapping it out. I’ve seen some people talking about capacitor problems but still running their miners. Since this cap is close to the power inputs, I assume it helps smooth out the input voltage. What do you think? Is there a chance I could mess up the board if I try to run it like this? Should I test it with just the other two blades connected at first? Thanks!

If you see those caps are broken then you must replace it. I don't know what you mean exactly about the miner still running even if it has busted caps but I believe without those caps I'm sure it will kill other components so it's recommended to replace them.

You must remove the broken capacitor and replace it. And replace the fan screw with the appropriate length. Electrolytic capacitors need to be soldered with a soldering iron, and when soldering, pay attention to the correct installation of the positive and negative electrodes of the capacitor.

Soldering to the ground plane of a hashboard With a soldering iron is a difficult operation, you may just find your crown plane is dissipating more Watts than the soldering iron is supplying. This is going to lead to a pseudo-solder  or cold solder joint. Mitigate this issue by bringing your board up to solder melt temperature with hot air first.
