Thermalright Ultra-120 eXtreme Rev.C, Cogage Arrow and Zalman CNPS10X Flex
 

As you probably know, tuning is the process of modifying a car to improve its characteristics or appearance. It allows to achieve a higher output power from the engine, make the aerodynamics of the car more efficient or just make the car look special and unique. What you probably don’t know, CPU coolers can be tuned as well. The only difference is that this kind of tuning is done by the manufacturer of the cooler rather than by a third party. The manufacturer adjusts its cooler design by introducing small changes in order to increase performance or reduce the manufacturing cost. Sometimes such changes are only limited to the product’s exterior design and do not affect its noise level or price.

This review is about three coolers that have undergone such modification and the effect it has had on them: Thermalright Ultra-120 eXtreme revision C, Cogage Arrow and Zalman CNPS10X Flex.
