Computer Base (German language, Google-translated link here) has rounded up five CPU water blocks to see which might offer the highest performance on their Intel Core i7 3960X-equipped testbed.

The tested water blocks include:
- Alphacool NexXxos XP3 Light V.2
- Phobya UC-2 LT
- Raijintek CWB-C1
- Heatkiller IV Pro Pure Copper
- XSPC Raystorm Pro
The review offers an thorough look at the design of each water block, as well as an interesting look at the effects of flow-rate on performance:
"The test has been shown that with increasing flow rate decreases the temperature difference of the water before and after heat sinks. However, the question arises whether a higher flow also has a positive effect on the cooling performance itself. A negative effect of increasing flow as well: Most pumps are unthrottled very loud to work, so that a reduced pump capacity is useful for a silent water cooling."
