Add a Variable Speed, PWM-controlled Cooling Fan to your Computer CaseThe FAN12025PWM 120mm PWM Case Fan adds an efficient air cooling solution to computer cases or other enclosures to help ensure optimal performance from internal components. With Pulse Width Modulation (PWM) technology, the fan speed can be dynamically controlled by the motherboard, so the fan runs at a speed that suits the operating conditions - lowering power consumption and fan noise when the system is idle, and delivering maximum cooling under full load conditions. Backed by a StarTech.com 2-year warranty and free lifetime technical support.The StarTech.com Advantage- PWM control enables the fan to be controlled by the motherboard according to current system requirements, ensuring optimal system performance- Ever Lubricate bearing design increases reliability and lifespan over fans with a traditional sleeve bearing design- Backed by a StarTech.com 2-year warranty and free lifetime technical support

Add four RS-232, RS-422, or RS-485-capable DB9 Serial Ports to a desktop computer via PCIe x1 Expansion CardAdd serial communication support to a desktop computer or Small Form Factor (SFF) system, using this 4-Port Serial PCI Express Card. The four DB9 ports can be independently configured to support RS-232, RS-422, and 2/4-wire RS-485 standards, for communication with compliant serial peripheral devices.Per-Port Serial ConfigurationThis PCIe Serial Card is equipped with on-board DIP switches, enabling each DB9 serial port to operate in RS-232, RS-422, and/or RS-485 mode(s). The card features LED indicators per port, providing real-time monitoring of port activity.Configurable External SATA PowerThe PCI Express Serial Adapter Card features three power modes that are configurable via on-board jumpers, including 12V (1.5A per port), 5V (1.5A per port), or no power (RI), over pin 9.Legacy ConnectivityThis serial card enables the continued use of legacy serial devices, preventing down time and avoiding costly upgrades. The 4-Port PCIe Serial Card is an ideal system upgrade for a wide range of applications (e.g., point-of-sale terminals, PLCs, factory control and automation, scientific sensors, medical equipment, scanners, and oscilloscopes)The StarTech.com Advantage
