Need help choosing a GPU water block

[redmike12]

Hi!

Need some help choosing the right block. I have 2 ASUS Dual GeForce RTX 2080 in SLi. The top card is running 71C at idle with air. I think that my only option is water for both cards. I have an AiO for the CPU. However my MB is Asus ROG Maximus X Formula, so maybe I should consider including the MB in the loop. 

Any advice is appreciated.

71C at idle is pretty extreme, is there enough airflow? Before you drop a few hundred on a custom loop for your cards, experiment with some different airflow schemes. Even if you go water, you'll still need to blow cool air across the radiator.

They even make blocks for the dual?

 

got money for dual 2080’s, doing a full loop would be easy and the best option. 

Even lesser single card systems could use a full loop.

Running 3 120mm in the front for intake, 1 120 in the back for exhaust. and 3 120 for the AiO on top of the rad blowing in.

So you have 3 heat source all blowing in and around and 1 fan to blow out. There’s on issue. Did you happen to test temps the panel off and/or all case fans at max?
