Damaged GPU due to water exposure
Damaged GPU due to water exposure
The best method would have been to rinse in clear water before the card had time to dry up. But it's too late for that. The problem with calcium and other deposits is that they can be conductive. So, as soon as you plug the card and power up the computer, the card can experience a short circuit and die a horrible death. What to do now ? You can try removing the calcium build up as much as you can with a dry toothbrush. It won't be a perfect job, but it's still better than nothing (and easy to do). If you have access to an ultrasonic bath, you can disassemble the cooler and fans and dip the pcb into the bath to clean up all residues. You should also redo thermal paste and thermal pads while reassembling. And if you think the card is not worth the trouble, you can simply try powering it up. There is a chance it will work flawlessly, and a chance it will die. I rarely seen a card partly working, partly dying. Hope that helps
The calcium isn’t causing any problems; just take it apart to ensure the PCB and parts are free of debris, or wipe them down with alcohol and a gentle brush—avoid anything rough.
