While even I have not read the entire thread, some of these questions are going in waves. Curse of a long popular thread
... not a bad problem to have, huh Swiftech reps? However for your reading pleasure, here are the tips I have read so far:
While filling the res must be before and higher than the pump so that the pump never runs dry. Once the loop is full, it does not matter. You could move the res lower than the pump once full. So since the H220 has a rad with a built in res, you would have to have that hole assembly higher until the loop is full. And since it comes pre-filled this is only an issue if you are draining, expanding, and refilling the kit. Once the loop is full, you can place that res/rad combo in any position. You can also top it off from any position as the res will bleed off air at the top of the res no matter where it is in the loop. That is the primary purpose of a res. I don't know exactly how it does this, must be a pressure thing. At least that is what I have observed and read.
The next thing to remember is to connect the parts in the loop in the most direct way possible as there is very little temp difference between the hottest part to the coldest part in a waterloop. So where you place the rads in a loop hardly matters as far as order of components go.
And lastly, the rule of thumb is to have 120mm of rad area to each waterblock plus one more for 120mm of rad area for overhead. Then pile on some more rads for silent running if you like. That way you could increase your performance and keep those fans spinning low.
