Flow layout with submerged pump?

Ok, so I have all my systems parts on the way and I am wondering what order I should route my water through the system. I have a 500 GPH pump with res, a heatercore. and a Maze3. Now people have said that a submerged pump will heat the water (though I havent seen much proof of this). So my question is why dont I just run this flow layout:

pump -> rad -> WB -> pump

This way any heat from the pump will be dissapated by the rad then go to the waterblock, then hopefully a small amount of WB heat will dissapate in the res and then also the rad again. Is there any real problem with this setup? Anything I am overlooking? Thanks all.

That's how I'd run it. Looking good....make sure to post temps on that shiny new maze 3, I'm sure everyone's curious as I am.
I dont use a rad, but thats the way mine is setup. My theory is that cooler water will be sent to the cpu. I dont really know how much difference it would make, you would have to try it both ways in your own setup to find out.
