NZXT has just released the Kraken X31, a smaller and more affordable Kraken liquid cooler. The Kraken X31 features a 120mm radiator, which is optimized to run on a single fan without losing static pressure, airflow, or performance. The Kraken X31 also has an integrated variable speed pump that keeps noise to a minimum, with a 120mm pressure-optimized PWM fan connected directly to the pump. Users can control the Kraken X31's fan speed and other settings with CAM, NZXT's new software suite for the Kraken. If you need some liquid cooling, you can have the Kraken X31 for US$79.99 at the NZXT Armory Store, though it's only expected to ship out in mid-July.
