ARCTICF9 - PC Fan, 92mm Fan, PC Case Fan, Quiet motor, Computer, Push- or Pull Configuration, Fan Speed: 1800 rpm - Black

Bought this fan to cool my zig controller when on electric hook up

Bought mine to put in a project (not a pc or printer power supply or anything like that) for general airflow and partial boundary cooling of the power supply, amplifiers and mixer module.They are pleasantly quiet at the rated 1800rpm. (At least when new as mine are)Moves a reasonable amount of air unrestricted, if restricted then I would recommend the 92mm pressure oriented version.I would recommend them to anybody.Voltage range is huge and will reliably start down to 2VDC.If your application goes above 12v then YMMV. Likely run at 14v for a couple years but don't push your luck.I scoped the tach signal with my DC coupled DSO and it varies between about 2-12 unloaded depending on speed and supply voltage.Fan behaved nicely when run on limited current or limited voltage.Will likely be fine in a two wire pwm situation if needs be.Square wave -- Two pulses per rotation.EG: 60hz/2=1800rpm. 30hz/=900rpm.And so on.Comes in a small box with 4x self tapping screws.Motor itself runs warmer than other fans I've had but it's perfectly reasonable.

Quiet motor easy to install pleased with the purchase.

Good fan. I used it replace a fan in a linear power supply and it has more than halved the noise at full speed.For the price it's great.

I have used a lot of Arctic fans of the years in various builds, they provide noise levels and static pressure on par with equavelnt sized Noctua fans for a fraction of the price. I have had to replace a fan in a home server though after a year of constant use as it developed a really noisy bearing whine when in use. This only happened on one out of four installed fans, but something to be aware of.

Good quality fan. Very silent. Easy to install. Working perfect. Thanks.

Excellent for the price
