I like my water-cooling, and in recent years the CPU cooler market has lost it's attraction. However, I was intrigued by the design of the Arctic Square and was hopeful that it might prove to be interesting. Holding it in my hands for the first time I became more than a little concerned that it just wouldn't be able to perform all that well. It was mainly aluminium and quite light considering the size. Testing proved it to be quite the sleeper though, with load temperatures almost as low as the stock coolers idle temperatures.
