As you can see, performance of the Iceberg 240 is actually pretty decent considering it is a £60 liquid cooler. It doesn't quite challenge the Arctic Liquid Freezer 240, or even the Cryorig H7 Quad Lumi air cooler, but it is at the right end of the chart and can be considered a success in that regard.
Acoustics
Acoustically, the Iceberg is a mixed bag. Its fan are surprisingly quiet, even at their full speed of 1800 rpm, and that is certainly appreciated. However, as with many cheap AIOs, the downfall is the pump – it is just quite whiny and can be heard over the fans at all times.
Combining the alu rad. withe a copper block is not exactly smart.
There is something wrong with the numbers of the Arctic Liquid 240 (Asetek) and the other 360 and 240 water coolers. Asetek units have nothing different from the CoolIT ones and even DeepCool. And thickness is not better that surface area from what people say. The other aspect is that all these reviews never compare coolers in the same bracket. Where are the H100i and Cooler Master units? Given that Thermaltake and EVGA are also Asetek, there is not much too choose from, but I imagine Corsair and Cooler Master have NDAs forbidding comparing with same bracket coolers. DeepCool also have good 240 units.
