推荐型号：DARK ROCK 4、SHADOW ROCK 2、PURE ROCK
 
Bequiet！ Biku is a well-known PC accessories manufacturer in Europe, founded in 2006, and its power supply products have been the top seller in the German market for many years. Biku started producing CPU coolers in 2008 and is currently named the best air-cooled CPU cooler brand by techspot. Biku has not been in the Chinese market for a long time, its market share is not high, and its e-commerce flagship store is also in its infancy.
 
Biku's air-cooled radiators are divided into three series, and the target group is very clear. DARK ROCK IS AIMED AT SILENT AUDIOPHILES AND IS THE FLAGSHIP PRODUCT LINE; SHADOW ROCK IS AIMED AT DIY PLAYERS WHO PREFER LOW NOISE AND HIGH EFFICIENCY, AND THE PRICE IS SLIGHTLY LOWER THAN THE FORMER; PURE ROCK IS THE FIRST CHOICE FOR THOSE LOOKING FOR A BUDGET.
 
Its predecessor, the Dark Rock Pro 3, was critically acclaimed, winning not only the Red Dot Design Award, but also the Best CPU Cooler of the Year 2015-2016 by the European Hardware Association. The current Dark Rock Pro 4 is a cut above the former. The Dark Rock Pro 4 is 24.3dBA lower than its predecessor at top revs, and it can compete with the Owl Cooler. The appearance of Pro 4 inherits the design of the previous generation, the aluminum fins are anodized, and the surface of the fan and accessories is all painted black, and the overall sense is very strong, and the price is 699 yuan.
 
COMPARED TO THE FLAGSHIP SERIES, THE MID-RANGE SHADOW ROCK SERIES IS QUITE INFERIOR. SHADOW ROCK 2 IS THE TOP OF THE SERIES, WITH A 4-PIPE DESIGN AND A METAL SURFACE THAT IS NOT AS RECOGNIZABLE AS THE FORMER. The 120mm PWM fan provides a maximum heat dissipation capacity of 180W, and although the cooling tower is a single tower design, the heat dissipation area is comparable to that of other brands of twin tower designs, and fans can be installed on all sides. The fan noise control is good, and it is controlled below 26dBA when fully loaded, which is comparable to the Dark Rock Pro 3, and the price is 399 yuan.
 
If you're short on budget, opt for the more affordable PURE ROCK series, which doesn't compromise on performance. All air-cooled products with TF or LP are push-down cooling, and use the same fan as the same series of radiators, so consumers only need to choose according to the size of the case and personal preferences.
 
Overall, Biku products inherit the hardcore style of the German system, which is simple and practical, and the price is acceptable. Consumers should be aware that all Biku products will be marked with German quality on the billboard, but in fact they are OEM produced in Chinese factories. The merchant offers a three-year warranty, and you can warrant it at any time if you have any problems.
