Hey guys, I just finished building my loop and I was wondering how I should go about getting all of the air bubbles out of my loop?
Also my pump is quite loud is that normal?
 
I tend to leave the top of the res open (so air can escape), then lean the case this way and that to get the air bubbles out of the radiator, and blocks. When you've bled the system, the pump should quieten down a bit, as much of the noise you're hearing is the air in the pump.

I do this but leave the top on the reservoir in case any liquid is spilt whilst tilting the case.

Any air in the system will end up in the reservoir and you can just keep topping up as needed.
 
I leave the top on the res, remove any components that are not screwed down. Then with the pump on i rotate the case, chasing the air bubbles from component to component until they collect in the res. Smaller bubbles may remain in the tubing and the pump may be a bit gurgly every now and then but this usually settles in the following hour or so. If you have a variable speed pump run it as fast as it will go during this time to help push air out of the loop. After a few hours you should notice the water level in the res is lower as the remaining air collects in the res, simply top up and reseal the res :)

I lay the case on its side and tilt it a bit because my rad is at the top and res at the bottom, helps to have the radiator intake closest to the floor.

if I switch off my rig and the res still has some space in it for coolant will the loop fill up with the air in the res?

No the air just stays in the top of the reservoir, the only way it will get into your loop is if the air makes it into the pump by turning the reservoir upside down or something.
