Cryorig R1 Universal CR-R1B Dual Tower CPU Heatsink with XF140 and Xt140 Fans DirectCompress Soldering for 10% more contact surface compared to traditional soldering, and the more contact surface the faster the heat conduction. Heatpipe Displacement Optimization allows for better and more evenly spread heat conduction on the fins compared to traditional linear alignment. Jet Fin Acceleration System squeezes airflow and increases exhaust air speed. The increase of airflow speed in our Jet Fin Acceleration System allows heated air to leave the tower faster. Support Processors INTEL LGA2066/1151/1150/1155/1156 AMD FM1/FM2/AM4/3/2 Includes one XF140 and one XT140 high precision low noise 140mm PWM fans.
