Zalman included two of their best waterblocks with the Reserator 2; the ZM-WB4 Gold for the CPU and the ZM-GWB3 for the GPU. While not the highest performing waterblocks on the market, they are very good and should work well in a low-flow system like the Reserator 2. Both waterblocks come in retail packaging and include universal mounting hardware.
ZM-WB4 Gold CPU Waterblock
The WB4 Gold is Zalman’s newest CPU waterblock and incorporates a removable Lexan top (polycarbonate) and a pure copper base for optimum heat transfer. The WB4 uses a 12×12 array of square pins to increase the wetted surface area and the entire copper base is gold-plated to prevent corrosion. Water flows in thru the center fitting and exits thru the outer one.
The base of the ZM-WB4 Gold waterblock appears flat and exhibits a mirror finish.
The WB4 CPU waterblock is compatible with Intel P4 socket 478/LGA775 and AMD Sempron/Athlon 64/Opteron socket AM2/754/939/940.
ZM-GWB3 VGA Waterblock
The ZM-GWB3 VGA waterblock incorporates a light weight aluminum base that is anodized inside and out to help prevent corrosion. The new low profile design is now compatible with dual video card setups and features two barbed swivel fittings.
Zalman’s VGA waterblock is designed to work with the majority of video cards from both ATI and nVIDIA.
