Air flow/ fan set up help

[Bklynman671]

So I'm using a phanteks p350x case. Can only have a front mounted radiator so I'm using an aio and  I also want the rgb fans to be seen so I'm using it in a "push" config. The fans will push air through the rad out the front of the case( Fan...Rad...Case). My question is should the rear be an exhaust and the top 2 fans be intake? Or is there a better way ?

No, the top fans should be exhaust, and the rear fan should be exhaust as well. If the fans on your radiator are exhausting out of the front and they're between the case and the radiator, that's actually pull (the fans are puling air through the radiator into your case). If you are using a push orientation against the radiator be sure to pull the radiator out and clean it at least once every 3-6 months as dust will build up between the fans and the radiator. The front fans should be pulling fresh air into your case. You'll still see the RGB lights on the fans just fine with this configuration.

Well nothing is really stopping you from doing what you're thinking but you'll be fighting natural convection with top and rear as intake and front as exhaust. You also won't have any dust filtering on that rear fan. I understand the situation you're in as you don't want to be looking at the back of the fan when the rad is mounted in the front (wish they made reverse flow fans for this purpose).
