The GTX flows front to back instead of side to side like most other. There is a hot side and a cold side flow configuration at work, placing your fans becomes a bit more important. Some planning on your build is necessary here, depending on if you want the barb side to be the first or second pass. Using the right port as inlet and left outlet, the barb side is the first pass or hotside and the back is the second pass/cold side. Left outlet and right inlet makes the barb side the second pass cold side.
The above quote from skinnee must contain a mistake as he lists the Left as outlet being both coldd and hot.
I would like to know the correct fan orientation to use with these radiators to get the maximum performance out of them.
