Swiftech Apex Watercooling Kit Review

Filling the system was a breeze. I poured the bottle of HydrX into a cleaned out 1 liter soda bottle, topping it off with distilled water. Next I filled the system through the reservoir as the instructions show. Adding a little water, then tipping the case back, I got a good amount of water in the tubing. After powering on the system some more fluid was immediately required as the pump should never be allowed to run dry. After tipping the case and adding more fluid a few times, the fluid level was just below the inside edge of the fill-hole. I then let the system run for a while allowing all of the bubbles to work their way out of the system, which also gave me time to sit and check for any leaks or seeps at the connections.
