Insane coil whine after putting 5080 water block

[vapealot]

Hi guys

I really hope you guys have a suggestion. I finished a brand new system last week, everything is performing great, temps are very low, even with fans at <600rpm under stress test. However, after putting the block on my 5080 I have insane, and I really mean INSANE coil whine from this when under load. It is so bad that I literally get a headache and ear pain when gaming.

I have tried to loosen the screws on the back plate slightly and I have tried to under-volt the card but don't really know what else to try. The internet is full of shady solutions, super glue on the and such, most seem shady or stupid, so hope you guys can help.

I am desperate for a solution. I will try and drain the loop, take out the card, disassemble, re-paste and check everything tomorrow, but I have low hopes for this. If the reassemble don't have a MASSIVE miracle improvement, I will have to revert to the stock air cooler (where I did not observe any coil whine) and before you state that the coil whine was likely there before and I just could not hear it because of the stock cooler fans, then no, this was clearly not there before, or at least it was 500% less)

Coil whine is a GPU issue, not a cooler issue. The only difference between a water cooler and an air cooler in this context is that water blocks usually don't have thermal pads on the coils.

Sometimes, adding pads afterwards can help, but it can also make things worse. In general, coils don't need cooling. However, if the soldering on the coils is poor, the pressure from thermal pads can help reduce vibration, which causes the noise.

Other than that, there's not much you can do except return the card and hope that the replacement is better. It's not a new problem, after all.

Definitely, electric discharge there. without full see of computer start. I can say possible causes. static discharge, (over the capacitors), metal or hair is touching PCB routes or connectors. GPU card as some clearence in the PCI slot connector, or hair in the PCI slot connector. But it seams some of the capacitors are working over is treshold (cause missing or disturbing power loss).

Happenned with me, got to investigate properly the my problem. Has weight in the PCI slot connector got some clearence in the PCI slot connector routes, got to carfuly adjust the GPU card position. And I also do some cleanup in the PCI slot connector and the GPU card.

Did the coil whine reduce after you re-assembled the system?
