I am looking to build a flight sim PC in the Corsair Crystal 680x, and I have chosen all of my water cooling components, all of which are nickel. But now, I need a nickel rad. I have searched for a couple of hours and will continue searching. I also need to know what config of multiple rads I should use for best cooling performance. I will be using a Threadripper 2990WX and an RTX 2080ti also watercooling an ASUS ROG Strix x399-E gaming motherboard's VRMs, also I will be using a water cooled PSU.(literally the only one on the market) If anyone has any suggestions, I'm all open for suggestions. Thanks in advance!
