Review on ARCTIC P12 PWM PST - 120mm Computer Case Fan with Pressure-optimized Quiet Motor, White/Transparent, Fan Speed: 200-1800 RPM by Hayden Jay ᠌

You may use it as a cooler fan to cool the processor, and you can use it as a case for your computer. Very quiet, even at 1000 rpm. The sound is tolerable, however on my system, which features a large radiator and a processor with a low temperature of 47 degrees Celsius, this fan either does not turn on at all or only operates at moderate speeds. Under load, it may reach up to +/-1500 revolutions per minute, and the level of noise is respectable but bearable. At some speeds, such as 800 or 1100 revolutions per minute (rpm), it looks as though there is an unnecessary sound. It perfectly reflects the light and quite literally shines with the color that the case is illuminated with. I have it in white, but it does not have a backlight. However, the case does have a backlight. Extremely attractive:) The circulation of air is adequate. I would recommend spending your money on this.
