Best choice for PC case, CPU cooler, PSU and dropsy.
  
Best choice for PC case, CPU cooler, PSU and dropsy. The plain bearing is not very sensitive to high air temperature. Therefore, this fan will be simply indispensable at the back of the PC case for blowing hot air (well, hydrodynamic bearings dry out in hot air in half a year and begin to rumble, creak and growl ...).
+ Brand - Germany (meaning a sensible thing). Made - in China (means for an adequate price).
+ Material - matte plastic, hard, durable, does not crack when screws are screwed in, there is no smell.
+ There are no vibrations for two reasons: 1. The motor is attached to the frame on saber-shaped / curved plastic jumpers. They dampen vibrations like springs. 2. For high-speed (and here up to 2000 rpm) fans, only well-balanced impellers are selected in production.
+ Connection via 4 PIN connector in the motherboard, which allows you to configure the necessary graph in BIOS for the dependence of revolutions on the temperature of the processor. For example, if this fan will be used in a processor cooler, then it is better to use the entire speed range (500 - 2000). And for ventilation of the PC case, you can not overclock the fan to the maximum (800 - 1500).
+ Threaded sliding bearing. Quiet and durable for up to 80,000 hours of operation.
+ Air flow - cooler than others, really felt to the touch by hand.
+ Noise, with such a flow and speed - adequate. There is no noise up to 1300 rpm. More than 1300 - the air is noisy when passing through the grill of the PC case, but the unit itself does not make unpleasant sounds.
+ In the box - a fan and short screws. Screw it on, plug it into 4 pins and enjoy.
+ Old-timers say that this fan can be serviced. For maintenance and lubrication, there is a plug under the sticker. But with such a resource, things may not get to THAT.
- Sometimes you need long self-tapping screws and an extension cable / splitter. Wish it was included.
- Not bad to have rubber anti-vibration pads.
