Getting pretty bad coil whine after installing water block I was hoping somebody could help me figure out the best way to narrow down the issue and what steps I could take to get rid of it.

Possible useful information:

I have an evga xc3 ultra 3080 and I installed the ek vector waterblock for it. Before I converted to a watercooling setup there was no whine at all. The whine only occurs when I startup a game. Since this wasn't happening before I was hoping I could stick some electrical tape or silicone over the part that was causing issues.
