The conclusion can be quite simple. Of course HIS has another classic in their hands with this ICE4+ Turbo model. Though not perfect, we liked it very much. Next to all the customizations from the PCB to the cooling, it also has a little extra bite against the GeForce GTX 260 Core 216 cards as it was overclocked slightly.
What I'm not used to from HIS is a noisy product. To date, all of their products have been silent. And the IceQ4+ cooler therefore caught me off guard a little. Once that GPU gets hot, the RPM rises to ~2500, and exactly at that threshold it really starts to move around a lot of air, making it just as noisy as the reference cooler. The positive here however is that it cools better than the reference cooler. So that was the one thing that did strike me as odd, nothing major or extreme though.
