Alphacool today introduced the Eisfluegel Aurora RGB, a handy flow-indicator for DIY liquid cooling setups. Built in a clear acrylic housing with addressable RGB LED illumination, this indicator provides visual indication of coolant flow using its impeller, as well as precise flow-rate between 70 to 300 L/h, which it can communicate to software via a 3-pin fan-header on your motherboard (as RPM). The unit measures 45 mm x 45 mm x 39.4 mm (WxHxD), and features standard G 1/4" threads. The flow-rate sensor plugs into your motherboard using a 3-pin fan connection, while the ARGB lighting takes a standard 3-pin connection. Available now, the Eisfluegel Aurora RGB flow indicator is priced at 29.99€ excluding VAT.
