SilverStone Air Penetrator 180mm Fan Review

"The fan is not only well constructed and designed but you have the option of two speed settings. At low settings we were rewarded with low temperatures on the heatpipes during real world testing with the added benefit of virtually no noise at all. At high setting the noise became noticeable, but within a general enthusiast gaming chassis, 34dBa would be quieter than most CPU or chassis fans. This is a choice Silverstone have handed to the customer, and is something we like to see.

In the UK, the consumer cost is just under £15 inc vat which is clearly a very competitive price, especially for such a large fan with a radical new design implementation."
