It's better to have fins oriented towards the top of the card than towards the bracket inside Sentry because there's no fan in the GPU compartment that would help vent the card front to back. Some cards have most of the fins oriented to the side while the area near the bracket is oriented towards the bracket.
With that said, while it sounds like Inno3D card would be better here, it's not. From the photo you can easily see that it has extruded aluminium radiator which is cheaper way to implement it and it will limit the airflow because bottom of the radiator needs to connect somewhere and not like with a fin stack where air passes through completely. Apart from that, the extruded radiator will generally have less fins/more space between fins, so less heat dissipation area.
Apart from those issues, I wouldn't really take low end brands if you want to keep your system on the desk, unless there's a warranty that covers coil whine issues. Having a whining card next to you is not ideal.
