The aquastream ULTIMATE has been specifically designed for PC water cooling systems. Design goals such as high performance electronics, integrated fan controller, temperature sensor, OLED display and comprehensive control options were all met during development. And there is one other feature that should be mentioned here - the extremely low noise level of the pump. This pump features Intelligent pump controller for reduced vibrations and operating noise, High resolution OLED display and built-in buttons for direct operation without a PC, Integrated water temperature sensor, Steplessly adjustable 12 W fan output for analog 3-pin fans or 4-pin PWM fans, Automatic control of fan output and pump speed with individually adjustable behavior, aquasuite software for a comfortable setup, evaluation and visualization of all sensor data, aquabus interface for communication with Aqua Computer devices. (When connected to an aquaero, the fan output of the pump can be controlled from the aquaero), Connector for external temperature sensor, Connector for external flow sensor, Alarm output to protect the PC in case of a failure, Integrated buzzer for acoustic alarm, USB 2.0 interface, Firmware update via USB, 12 V power supply via SATA power connector.
