Yeah you'll want to read the coolant before it enters the engine. Because that is the coolant that has passed through the radiator. If its too hot to begin with, then you know its only going to get hotter... There is no need to read the temperature of coolant before it gets to the radiator (where you are reading it now).
Do whatever you can to help duct the air to the radiator and cooling panels like codyace has said.
