Nope, that's all screwy. First of all, you never want any bottom fans to be exhaust. All bottom fans should be intake because that's where the cool air is. Secondly, don't ever count the PSU or GPU exhaust fans, they have little to nothing to do with the air flow or transfer of heat from inside the case. If you can swap a 140mm fan from the side to exhaust in the back, depending on vent size and mounting holes, that would be an improvement. Your optimal case cooling would be improved using exhaust fans in the top of the case where your radiator is now sitting but since the radiator is there it kind of makes it difficult. Hopefully you don't have your front fans mounted inside the case on the HDD cage like the stock photos on the retail sites show. They should be mounted right up against the front of the case.
I'd consider moving the radiator to the front of the case, if possible, with your fans drawing intake there, and using the two top fan locations for exhaust.
