Thermaltake today introduced the Pacific TF2 temperature and flow-indicator (model: CL-W275-CU00SW-A), a useful accessory for complex water-cooling setups. You simply fit it across a coolant channel, and plug it into a USB 2.0 header. Additional power is drawn via a SATA power connection. An LED segment display gives you a live readout of the coolant temperature and rate of flow. It includes an audible and visual alarm. You can set warning thresholds for both, so you can quickly figure out if your setup has coolant leaks or is overheating. That's not all, the device even interfaces with TT RGB Plus software over the USB connection, and relay its sensor data to software. The company didn't reveal pricing.
