Rexflo 80, 92, 120mm PWM Fans
Rexus, ever hear of them? Neither had we until an ambitious representative had contacted us and sent out three of their Rexflo fans. Rexus does sell a number of different fans manufactured by Panaflo, Delta, Sunon, Evercool, and Nidec, but they also maintain the Rexflo series for fans that run very quiet and use PWM (Pulse Width Modulation) for reducing noise and managing the fan speed. The fans at hand today are the Rexflo 80mm, 92mm, and 120mm models.
The Rexflo DF128025BH-PWMG, DF129225BH-PWMG, and DF1212025BH-PWMG fans are compatible with three and four pin fan connectors, but only using the fourth pin will you be able to benefit from Pulse Width Modulation support. PWM can dynamically adjust the fan speed and thereby reducing the noise level. All three of the Rexflo fans we are looking at use dual ball bearings and have a life expectancy of 50,000 hours. The Rexflo 120mm fan can push up to 96 CFM of air while the 80mm and 92mm models can push up to 34.40 CFM and 55.39 CFM, respectively. With the other major area for concern, the Rexflow DF128025BH-PWMG, DF129225BH-PWMG, and DF1212025BH-PWMG fans have a maximum noise level of 29.50 dBA, 35.38 dBA, and 42.60 dBA respectively. The Rexflo products are all backed by a five-year warranty.
