Tower design CPU Coolers may have been around for roughly a decade now but it wasn't until a few years ago that several manufacturers thought about combining two heatsinks to make the main body of the cooler instead of one thus increasing its cooling potential. Dual tower solutions were later on called sandwich type ones since in between the two heatsinks some manufacturers placed a fan to increase airflow between the fins thus improving the overall cooling efficiency of the cooler (some used that one fan only while others used two and even 3 in push and pull configuration). Today we finally see most CPU Cooler manufacturers walk down that same path and although for the majority of consumers even single tower CPU Coolers offer the best bang for their buck for overclockers, enthusiasts and even professionals in some cases dual tower models are well worth the extra cost. Be Quiet! has been in the business of manufacturing some of the best CPU Coolers around and today we will be checking out their latest Dark Rock Pro 3 CPU Cooler.
