Scythe Gentle Typhoon High RPM series Review
Up Close: The Gentle Typhoon
In a world of coloured fans with bright coloured LEDs and fancy shaped cowlings, the Gentle typhoons do perhaps stand out simply because they are none of these things. The lower RPM series that you may be familiar with has a black cowling and grey fan blades, and to be honest has always looked to me as if it's been made from recycled wheelie bins. The high RPM series we're looking at today however is an all black affair, with the plastic looking a bit more glossy and refined than the lower RPM models. It is strongly recommended to connect the fans directly to the PSU supply by the 4 pin connection only. Each of the fans comes with a molex pass through as well as a tachometer connection for attachment to the Motherboard
Probably the most striking feature of the high RPM series is the circumferential stabilising ring. This ring is designed to aid the passage of air rearwards in a more narrow linear fashion. I can't help thinking that they also serve to add rigidity to the blades. If you've ever stood near to one of these when it's running you'll be as appreciative as I am of anything that adds strength to the blades. The picture below right also shows that the cowling is of the semi closed corner design, which may cause issues if you wish to mount these units on a CPU heat sink.
The sticker on the rear of the fan gives info with regards to operating voltages and currents as well as informing as giving the model number of the fan. For those not already "in the know", the AP 29 is the 3000rpm model (pictured below), the AP30 the 4250, and the AP31 the 5400rpm model.
