Zalman Reserator XT (Cont'd.)
Although fan speed can be adjusted manually, the default setting has the cooler running in Auto mode. This is also the mode the cooler automatically reverts to as soon as it is turned off - in other words, it is impossible to save a fan speed setting. Using a button, the backlighting of the display and the flow control on the cooler's faceplate can be turned off.

Zalman's cooler does not have any way of reporting the fan speed or the water flow rate to the motherboard for monitoring. Should the cooler fail for any reason, it will alarm the user to this fact by beeping. The PC, on the other hand, can only recognize the failure indirectly through rising CPU temperatures.
We tested cooling performance with the cooler set to its standard Auto mode as well as at its maximum fan speed, which we set manually. Despite its larger size, the Reserator XT can't quite measure up to the MSI/Hydrogen solution even at its highest fan setting. At 45 db(A), the noise level is also far too high for a water-cooling solution.

However, in Auto mode, the CPU temperature is only marginally higher, and the Reserator actually offers cooling performance similar to that of the MSI/Hydrogen bundle. As an added bonus, the noise level is not at all bothersome in this mode either. As with any other water cooling solution, you'll need to ensure that the chipset and the CPU's voltage regulation modules are sufficiently cooled in some manner, as there is obviously no airflow from the CPU cooler.
We don't recommend using the Reserator XT at the highest fan speed, since the noise level increases disproportionately to the amount of cooling improvement when compared to Auto mode.
At €350, the Reserator XT also costs much more than any of its predecessors. Considering its performance, the cooler is definitely too expensive, especially since Zalman didn't even think to include any kind of hardware monitoring functionality. The final score is based on the cooler's Auto mode.

Great article, but it mentions testing over 80 coolers - but I see only about 15 in the test charts. Where, for example, is the Tuniq Tower T120??Reply
