Custom liquid cooling systems have long been the preferred heat removal choice of gamers and enthusiasts, as they exhibit superb cooling characteristics and often require little maintenance after installation. Thermaltake's liquid cooling setups have been the perennial favorite of many hardcore PC users, and it's easy to understand why - Thermaltake-equipped systems can help enthusiasts reach higher overclocks and increased system stability because of the quality and craftsmanship that goes into every liquid cooling setup. Thermaltake's new ProWater 850i liquid cooling system promises better performance and decreased downtime due to maintenance, and that stems directly from the heart of the system - the P500 pump. This pump takes advantage of a 500 liter per hour flow rate and a hard-wearing ceramic bearing to send the cooling liquid coursing through the brazed copper waterblock and onto the automotive-style radiator. This unique radiator sports "Dimple Dimpled Technology" rather than traditional rounded-copper tubing, actually swirling the coolant through the radiator and increasing thermal transfer. The coolant is supplied by the easy-to-read transparent reservoir that also serves as a fill-port, and the liquid is carried by heavy-duty 3/8" clear tubing. The ProWater 850i is available now through most major retail and e-tail outlets.
