Driverheaven (www.driverheaven.net) just posted another presentation, this time of the Arctic Cooling series 3 fans. Here is a review quote for you:

“Both fans are virtually identical, except for the size of course. But they are different to the "average" cooling fan you will have seen. First of all, the fans have no actual frame. The only part of the frame that exists is the front section, where the fan comes in contact with the mounting surface. The cables of the fans are entirely sleeved and the connectors are black. The fan motor is held in place by four plastic legs, which are reinforced by two plastic rings.”
