DeepCool Killer Whale Premium Heatsink Review
 

The large top-down DeepCool Killer Whale Premium heatsink has a jaw dropping weight of 1,225grams, or 1.225kg. Connecting the hefty copper heatspreader on the Killer Whale Premium with the big array of copper cooling fins are six 6mm diameter heatpipes that are soldered to the former and press-fit over the latter. A large and moderately audible 48mm thick 120mm PWM fan hangs over the copper fins, spinning at 1000-1800RPM. The fan moves approximately 78CFM, while generating at most 52.6 dBA and at least 36 dBA noise.
