Tweaktown published a Thermaltake ProWater 850i Liquid Cooler Review.

Quote from the review: "Thermaltake played a large role in the evolution of the water-cooling phenomenon. With their manufacturing capability and R&D teams, the company has made improvements in the quality of components used and the level of skill needed to install a unit successfully. 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."
