Scythe announces the expansion of the popular and award-winning Slip Stream fan series. These new models combine the proven design of the Slip Stream series with the advantages of PWM control. Slip Stream 120 PWM (SY1225SL12LM-P) is controlled automatically by the mainboard PWM function in a range from 0 (+200) to 1,300 rpm (±10%) generating an airflow of up to 74.25 CFM. Operating the fan at such a wide fan speed range allows flexible control to provide low noise level and performance when it is required. Already known from Scythe Yaysa CPU Cooler, Slip Stream 120 PWM Adjustable (SY1225SL12HPVC) is now sold separately. The fan speed of this model can be adjusted between 470 (±30%) to 1,340 rpm (±10%) and 740 (±25%) to 1,900 (±10%) rpm. The PWM controller then works in the specified range only. Manual adjustments are applied by using the controller knob which can be accessed via a PCI slot bracket on the back side of PC. Slip Stream 120 PWM & V.R. (SY1225SL12HPVS) is the third new model. This version can operate as normal PWM fan with an automatically controlled speed range of 500 (±30%) to 1,500 (±10%) rpm. Alternatively, users can disable the PWM function and control the fan via VR knob manually. The control elements are placed in a PCI slot bracket as in the PWM Slip Stream Adjustable. Scythe Slip Stream 120 PWM (SY1225SL12LM-P) is listed with a MSRP of 7.25 EUR (excluding VAT) or US$ 9.80 (excluding tax). Slip Stream 120 PWM Adjustable (SY1225SL12HPVC) and Slip Stream 120 PWM & V.R. (SY1225SL12HPVS) are available for 8.25 EUR (excl. VAT) or US$ 13.80 (excl. TAX).
