What Sets the H2O-320 Edge HD kit Apart
At first glance, with the box now open, the most obvious things are the inclusion of a second bottle of HydrX coolant and the Apogee HD block is moved up to the top to accommodate the MCR320 in this kit.
Digging a little deeper, along with the green twins, there is a radbox and its hardware included, and even though slightly out of focus, you can make out the word black on the Apogee HD box. There is of course an increase in the wiring adapters for the extra fan, and also more screws and optional hardware for the same reason.
Just a little side by side shot so you could more easily compare which of these to buy with your kit.
Just because the POM that the top is cut from is now black, that doesn't make it any lesser in the form of options as the white top has.
Even on the black version, the fittings still have the white painted logo on them. With the clear tubing, it would be cool to see them, but the clamps provided will soon cover these from view.
Set side by side, you can get a better feel for the size increase with the MCR320. Since you need to also add in the additional length of the reservoir ends and the pump at the other, it may restrict the use of the 320 in some cases that will allow just a triple radiator and not much more.
All three kits are now assembled and from here I need to fill and bleed the pair on the left. The older version on the right is running the older mix that was shipped with it, but the hose has long since been replaced and is now sporting some 3/8-inch ID Fesser tubing.
With both loops filled with the UV reactive green coolant, all that is left is to take these upstairs, bleed both loops, then get to the reason we are here, to see how they perform.
