Coolermaster's Nepton 140XL self contained liquid cooling system uses a 140mm wide heat exchanger designed for two 140mm PWM fans mounted in a push-pull configuration. The fans operate at 2000RPM-800RPM and generate a fair to minimal amount of noise, while moving between 122 - 54CFM of air. The waterblock is connected to the heat exchanger not by tiny little pipes, but via larger diameter, 15.5mm O.D. FEP tubing. Larger diameter tubing means more coolant can circulate through the waterblock compared to models like the Seidon 120V. The tubing is 35cm long to better suit large gaming chassis where the Nepton 140XL's radiator is most likely to be installed at the top of the case. Many early generation all-in-one's use 24cm or 30cm lengths of tubing that can make routing difficult in certain PC chassis.
