( I do see the rads are bolted to rad mount tho) Just an FYI
What DaaQ said.
You have enough room in the top and bottom for fans on both sides of each of the radiators.
See my build log (in signature), which is also STH10 and all full AQ build.
This picture has 2xTriple Fan AQ copper radiator. Each of the radiators is sandwiched with fans. So in total there are 12 fans there .
If your Inlet port (the one shown in red circle in picture), is on the top, the air needs to flow as shown with red arrow. If the inlet port is on the bottom then the air flow is other way.
However maximum you can go in STH10 is 3 radiators in top and bottom, because you need room for PSU.
