It is recommended that the radiator be placed on the same level with the PC case. Not higher or lower.
I had to put pieces of foam plastic under the radiator to lift it up to the necessary level. But good for me, the Reserator 2 is a perfect match to the design style of the ASUS Ascot 6AR2-B system case.
After you’ve made up your mind as to the position of the radiator, you should measure and cut up the connecting pipes. Then, put the pipes through the included bracket for the back panel of your system case, get their ends on the fittings of the water-blocks and fasten them with braces. Then you insert the fittings you have taken from the pump-up pipe into the ends of the pipes you have put out of the system case for the radiator and close the system. The manufacturer recommends that the liquid from the output fitting (and the appropriate pipe) go to the CPU.
Assembled and filled up, the system looks quite aesthetically inside the system case, to my mind:
The system case seems uncommonly roomy after gigantic super-coolers. You’ve got free access to every component. Unfortunately, the manufacturer didn’t provide anything to cool the near-socket space on the mainboard, but in my system case that was performed successfully by a 120mm fan installed on the side panel opposite the CPU socket.
Next I started the system up. The Reserator woke up with a barely audible squeak. The water flow indicator on the front panel began to rotate, but somewhat languidly, to my mind. And really, when I saw how slowly the pipes and the CPU water-block were being filled up, I realized the pump was indeed too weak. Moreover, take a look at the CPU water-block:
It is empty by a third! If the pump were twice its actual capacity, this emptiness might be avoided. Fortunately, this problem is easily solved on the LGA775 platform by simply turning the water-block in such a way that the output pipe is higher than the input one:
But what about users of mainboards for K8 processors whose CPU mounting frame is in parallel to the back panel of the case, which is quite a common thing. Well, there is nothing you do about that. You have to put up with the emptiness and, consequently, loss of efficiency unless you replace the water-block.
This is the payment for silent operation which is emphasized by the developer as the main feature of the Reserator 2. Installing a more powerful pump would inevitably increase its noise. To be more exact, it would make the system audible. By the way, the user manual included with the Reserator points at the opportunity to install an external pump into the circuit.
As for noise, it is totally missing here. The coolant does not babble in the pipes and radiator while the pump is silent. Telling you the truth, you can hear it, but only if you comply with five requirements: 1. say your neighbors to be quiet, 2. shut up all the doors and windows in your room, 3. disable all the system fans and, desirably, the PSU fan, 4. disable HDDs, 5. lie down next to the radiator and put your ear to the bottom of the aluminum pole the pump resides in. It is only then that you will hear it! So, the term noise just cannot be seriously applied to this liquid cooling system from Zalman.
I’ll show you its specs now and test it then.
