Pricing water cooling and can't find water block for GPU

Looking for a water cooling block that will fir the Gigabyte R9 390X. Searched Google and many websites have not been able to locate one. Maybe they aren't being made yet I don't know noob to water cooling. If you know of one could you please link it. Or would I have to use a universal one?

Not sure if universal ones would fit, at least not the swiftech ones I have. Bought a 390 nitro, once cpu block comes back I am going to take a closer look. Haven't heard if 290 blocks fit, been keeping an eye out for people watercooling these cards.

ek has a list of 290x blocks that are compatible with the 390x cards.. can't remember where to find it but it's out there.
Edit: nevermind Gigabyte isn't on the list but literally every other vendor is.

The only reason I was going to get gigabyte was because it's the only all black one but if I am going to void the warranty and water cool it I guess I could get a different one as color of the cover doesn't matter
