The Raijintek Ereboss is a small cooler compared to the likes DeepCool Assassin
, Noctua NH-D14 and other similar coolers that use 140mm fans. Raijintek took the typical tower design and added large platform aluminum fins to increase the overall cooling performance. It is paired with a thin 140mm PWM fan which can spin as low as 650 RPM to keep things quiet. You might be wondering if a single fan is enough to equal a top performing cooler. We will find out shortly.
