Zalman ZM-WB5 Water Cooling CPU Block

- Replaces the Zalman ZM-WB4 PLUS Water Cooling CPU Block- Replaced by the Zalman ZM-WB5 Plus Water Cooling CPU Block

Zalman's ZM-WB5 offers improved cooling by 1-2°C over the ZM-WB4 GOLD and ZM-WB4 PLUS by its use of internal cylindrical fins to improve flow circulation. It is a beautiful-looking CPU water block and has a pure copper base which has been gold plated to prevent corrosion and further improve heat transfer. It has an aluminium cover for maximum safety. Compatible with Intel's LGA775 along with AMD's socket AM2, 754, 939 and 940, this cooler is an ideal block for any watercooled PC system.

Customer Reviews

Excellent no-nonsense water block


The WB5 is solidly built and comes with a wide range of connectors to fit to different hose sizes. It achieves excellent thermal connection between the water and the CPU, with the CPU literally only a degree or two warmer than the water supply. A noticeable improvement over the old WB3 and WB4 blocks from Zalman, and they were pretty good to start with. Also fits AM3

Super cool!


A very high quality product, easy to assemble and fit with an excellent kit providing everything you need including the LGA775 backplate and pre fitted barbs. The Low profile allows for smooth pipe routing minimising kinks and flow problems. My overclocked Celeron D 325 2.53/2.9Ghz temps dropped from 60 to 32°C at full load over the stock Intel copper slug cooler. I fully recommend this block. On the back of this one product I will be investing in more Zalman blocks for the north, south bridges and graphics card. Excellent service and speedy delivery thanks Quiet PC :)
