The Thermaltake ProWater 850i is a step above the company's entry level water cooling kits and is a good choice for those looking for stable performance with a low acoustic footprint. The fan is able to crank up to very high speeds, giving overclockers who are less worried about noise and more focused on performance the opportunity to let their system run wild.
The construction of the components in the system are above average quality and everything fits together nicely. Thermaltake has loaded the PW 850i with enough UV reactive tubing to ensure a smooth build while dressing up the look of what would otherwise be just another kitted water cooling system.
Overall, the Thermaltake Pro Water 850i has everything a first time or above average computer user would want to find in a pre-built component kit. Enthusiasts looking to pull the most out of their system will opt for individual components to achieve the best possible performance of all their parts, but at a much larger, pro level price.
