how to set up airflow in 650D with 3 rads

post #1 of 3
Thread Starter 
Hi folks!

Im planning to watercool my 650D.

Originally i planned to use one dual 120 in the top and one single 120 at the back.

But now im thinking of adding an 140mm or possibly 200mm rad in front as well..

How is the best setup for airflow ? both the single 120 in the back and the dual 120 at the top on exhaust and the 200mm in the front on intake ?
Or is there another way to get better temperatures ? ..

any thoughts on this ?


thanks guys smile.gif

Because hot air always goes up I think you config you have listed will work best

Well, not exactly. It depends what you're cooling actually. When I had 2 580's and my 2600K I would get not bad temps (200mm pulling, 120.1 rear exhaust and 140.2 top exhaust).

As soo as I added the third card and started to fold, things didn't look so great. What I did was get everything to pull in the case (all rads get ambient air) and made a custom side panel with 4 exhaust fans. I now have no more problems, and themps inside the case while folding are at about 34C with 22C ambients.

So again, depends on what you're cooling...
