RESERATOR1 V2 Fanless Water Cooling System (w/WB5+)
(1 customer rating / 1 review)

Zalman RESERATOR1 V2 Fanless Water Cooling System (w/WB5+)

- Replaces the Zalman RESERATOR1-PLUS Fanless Water Cooling System

Behold the Reserator1 V2!

The RESERATOR1 V2 is designed for optimal heat dissipation using Zalman's HCET (Heat Capacity Extrusion Technique) technology. As a result, this cooler achieves excellent cooling performance using natural convection, making the RESERATOR1 V2 a very efficient fanless (therefore silent) water cooling system! Unlike any aircooled system, the RESERATOR1 V2 has the ability to keep a processor at just a few degrees above room temperature regardless of CPU speed. This gives tremendous potential for reliability and overclocking.

The name RESERATOR is a compound word derived from 'Reservoir' and 'Radiator' - the impressive cylindrical tower acts as a reservoir whilst simultaneously radiating heat!

  1. 100% fanless watercooling unit
  2. Supplied with CPU water block (ZM-WB5 PLUS)
  3. Supplied with VGA water block (ZM-GWB3)
  4. Supplied with anti-corrosion coolant (ZM-G200)
  5. Supplied with quick release couplings and clear tubing
  6. Northbridge waterblock available separately (ZM-NWB1)

The RESERATOR1 V2 supersedes the (black) RESERATOR1-PLUS, which in turn superseded the original (blue) RESERATOR1. The most obvious difference is the change of colour to a very cool-looking gloss graphite silver, but there are several other improvements too.

RESERATOR1 V2 Kit Contents


The most striking aspect about the RESERATOR1 V2 is the tall cylindrical reservoir where all the water is held. It stands nearly 600mm high and weights 6.5Kg. The graphite silver gloss finish looks even better than the RESERATOR1-PLUS's gloss black finish.

CPU Water Block, ZM-WB5 Plus

The ZM-WB5 Plus is Zalman's latest and best-yet CPU water block. It incorporates a pure copper base for excellent heat transfer, and the cover has been anodised to prevent corrosion. The ZM-WB5 Plus supports Intel Socket 1155/6 and 775 and AMD Socket 754/939/940/AM2/AM2+/AM3 CPUs, and is designed to be lightweight and easy to install.

LGA2011 Compatibility - Zalman have release the ZM-OC2011 that makes it possible to install the ZM-WB5 onto LGA2011 motherboards.

VGA Water Block, ZM-GWB3

Zalman's new VGA water block is light weight due to being manufactured from pure aluminium. This high performance VGA cooler is anodised and coated to prevent corrosion. The VGA water block is compatible with certain graphics cards that have push-pin holes around the GPUs.

Anti-Corrosion Coolant

The Anti-Corrosion Coolant supplied with the RESERATOR1 V2 has been designed to prevent corrosion, not only to the RESERATOR but also other materials it comes into contact with including copper, aluminium and plastic. This provides peace of mind for long term operation. It is to be used in conjunction with distilled water only!

Quick Release Couplings

Another great feature is the Quick Release Couplings. The fittings incorporate valves that prevent leaks when disconnecting the tubing. This provides a quick release mechanism allowing the user to move the PC and RESERATOR1 V2 more easily.

New PCI Bracket

Other features/items that require a mention include the new PCI bracket that is supplied with the RESERATOR1 V2. Instead of the bolts used on the older RESERATOR1, the new version allows you to pass the pipes through the specially designed PCI bracket and then into the RESERATOR using the Quick Release feature. This makes moving and replacing the liquid much easier.

Flow Indicator

The Flow Indicator is exactly the same as the one that was previously supplied with the RESERATOR1. The Flow Indicator shows movement of the water offering peace of mind that the water pump is switched on and fully operational.

Customer Reviews

Excellent product


I have a Rampage Extreme mobo with an Intel Core2 Quad Q9650 which is not overclocked. I have only cooled the processor and have noticed that the core temperatures which were running at 60C under full load have now reduced to about 48C. When I installed it I connected all of the piping to the CPU, then through the holes in the case to the Reserator and ran the device for about an hour to check for leaks. As there were none I then connected the CPU heat sink to the mobo which required very little pressure.

As the pressure I needed to use to get the tubing on to the heat sink was considerable I am glad that I did it in this order to avoid the possibility of damaging the mobo. It has been running for several days now and as I have been able to reduce the speed of several of my case fans, there is very little noise so I have to use my eyes to see if the computer is running, instead of my ears.
