ZALMAN Reserator1 v2 Review


Welcome to an independent hands-on review of Zalman Reserator1 v2, top-notch PC water cooling system.

Like million times before, one of the fans on my machine went out of axis and started making non-stop annoying rattling noise. Since there were 3 fans in total there (CPU, VGA, PSU), I could not pinpoint exactly which one gone mad, so I decided to do a complete overhaul.

PC water cooling solutions are on the market for quite a few years now, so I reckoned that the technology is mature enough to give it a try. Since water cooling solutions that include one or more fans defy the purpose for me, I turned to ZALMAN's completely FANLESS water cooling solution named Reserator1 v2.
Search for Zalman's european distributor yielded Quiet PC, online hardware store specializing in PC cooling solutions. About a week later, the box arrived.


The box that came in, 770mm x 290mm x 420mmm weighting around 14kg

Label on the box

The CD is there for size comparison

My cat got really interested in all the nice pictures on the box :)

Top compartment: tubes, 4m in length, 8mm inside diameter with 2mm wall

Reservoir + Radiator = Reserator, the beast itself

This version shipped with a british power plug

Zalman's top-notch workmanship

Not a single sharp edge on the whole unit, completely safe to handle

The famous auto-lock, minimal spill, inlet and outlet Quick Release Couplings

Top cover is a screw-on job

Interesting radiator fins configuration

Additional box contents: CPU Water Block, VGA Water Block, 0.5 liters of coolant, a slot bracket and tube Quick Release Couplings

Zalman's CPU Water Block retention mechanism, on the backside of the MBD

CPU Water Block fits easily, a real joy to work with

The lucky receiver: ATI Radeon HD 6850, Barts (40nm), 775MHz, 127W TDP

VGA Water Block installed and ready to go


To complete the picture we added Zalman ZM600HP, 600W heat-pipe aided PSU

Heat-pipe radiators help keep top 120mm fan working at minimal possible speed

Modular cabling panel configuration

When plugging Quick Release Couplings, no liquid is spilled whatsoever

When unplugging Quick Release Couplings, usually two or three drops of liquid show up, but not more than that

The flow indicator should vibrate to indicate the coolant flow, but this one does not

We opted to use supplied PCI bracket even though the case has it's own pipe holes.












There is plenty of room for cables on the rear side of the case

Top to bottom: Zalman's inbuilt front panel, DVDRW and A-Data XPG 2.5" Dual SSD Bay

Tight fit, only few millimeters spare and my desk is exactly 710mm high


Tubing connected

...and lift-off! Machine up and running
