Water Blocks ( Liquid Heat Exchangers )
Water blocks are the most efficient method of heat removal. They are often 4-5 times more efficient compared to a standard heat sink and fan.
The principle is simple: you provide a source of cool liquid (typically water) to the inlet of the water block. The liquid travels back and forth through the various chambers of the water block thereby absorbing the heat. The warmer liquid then exits the water Block.
The source of the liquid can be;
- Building (tap) water - This water is usually cooler than the ambient air temperature. The warmer exiting water can be sent to a drain or re-used in a number of ways.
- Chiller Liquid - A pre-chilled Liquid (typically alcohol or water/glycol) from a recirculating chiller passes through the water block and then is returned to the chiller for re-cooling. This source typically is a closed loop sytem.
- Well water, lake, or stream water - This water usually requires pre-filtering but can be substantially colder than ambient air temperature, especially during winter months. Exiting water can either be returned to the source or re-used.
- Radiator closed loop - a liquid (water, propylene glycol, or a mix of both) enters the water block at approximately ambient air temperatures. The exiting liquid then goes to a fan cooled radiator of sufficient size to cool the liquid back down to ambient air temperature. The liquid is then sent back through the water block, This is a closed loop system.

How to get the most out of a water block
- Always use the largest tubing diameter possible. The goal is to maximize the liquid flow through the water block. Larger tube diameters allow a greater flow with reduced friction.
- If the water block has a small inlet such as 1/16" NPT, use a larger tubing diameter for the rest of the system and then step the diameter down just before the water block. Step the diameter back up after the water leaves the water block. This keeps the pressure and flow rate maximized.
- Keep tubing lengths as short as possible. Unecessary tubing slows the water down and creates more pressure loss.
- Increasing flow rate through the water block will remove heat faster, thus giving a lower thermal resistance.
- Increasing the pressure will increase the flow rate. For example, a small pump producing only 2 psi may have a flow rate through the water block of 0.5 gpm (gallons per minute). A pump generating 10 psi could increase that flow rate to 1.0 gpm, and building (tap) water at 50 psi could have a flow rate of 3-4 gpm.
- If you have a closed loop system, use distilled water and add about 5% propylene or ethylene glycol (antifreeze) to prevent corrosion. Adding antifreeze will also lower the freezing point if you are chilling the water down into that temperature range.
- Water has the best heat transfer ability of just about all liquids except for some very toxic and expensive heat transfer fluids. Only use the minimum amount of additives (glycols, corrosion inhibitors etc.) necessary.
- Bleed all air out of the water system. Trapped air bubbles restrict and slow the water path.
