Here's a few things to check first.
Did you verify that the fan is wired and oriented correctly? Does it move enough air to cool the engine? With the cap off can you see coolant flowing through the cores?

Air could be trapped in the system. It will work out over time (and temps will come down), but there are two generally accepted ways to speed the process. The first one is to jack up the front of the car to raise the filler neck on the radiator higher up in the system. This will accelerate the movement of air pockets through the system, but it may still take a few days to get all of the air out. The second is to fill the coolng system and run the car with the cap off to prevent pressure from building up. Let it run until it reaches operating temperature. As air in the system is released the coolant level will go down. Keep adding coolant until the level remains constant or bubbles stop coming out of the system. Once this is done you should be ok.

Oh, and hook up that PCV valve to manifold vaccum or into the bottom of the air cleaner if it has that provision. It has nothing to do with cooling, but it should be hooked up to prevent pressure build up in the crankcase. It's not really doing anything the way it is. If you're against hooking it up, run a second breather.
