I was hoping to get some advice on radiator placement for the radiators from my cpu and two gpus with hybrid kits. I started with the following set up but I was hitting temps of 65c-69c on the top card (rear radiator) and the radiator for the second card was below the pump which is not recommended and hitting temps around 62c.
I figured the high temps on the top card could be attributed to the warm air coming from my bottom card and from my cpu radiator exhausting through the radiator of the top card. After doing some research and thinking about it for a while, I decided to buy a new AIO cpu cooler that had longer tubes than my previous one and mount it at the very front. Leaving the middle mounting point for the two gpu radiators, one in the top spot and one in the bottom spot (top radiator covers the middle a little bit so I had to put the 2nd at the bottom rather than middle).
This setup still leaves the radiator of the bottom card slightly below the pump, which again is not recommended. Given my options, this is the best I could come up with. For reference, ambient temp was around 72f when the given temps were recorded. Also, I am trying to stay away from custom a loop given how much I've already spent on my current equipment. I've been at this for a few days so any advice would be greatly appreciated.
