Thermaltake ProWater 850i Liquid Cooler

Specifications, Availability and Pricing


Water cooling kits are made from several components. In most cases these components can be swapped with other components, and you can even add more water blocks to cool chipsets and graphics cards.



The ProWater 850i water block comes with mounting hardware to fit the above applications. The block is very diverse and works with both modern AMD and Intel systems.



The block uses 3/8 inch tubing and is made of copper. Some consider the waterblock to be the most important part of a water cooling system. The block has the responsibility of pulling the heat from the processor and distributing it to the water passing through.



For me and those that have been running water cooling for a long period of time, we realize that the radiator, in terms of the kits ability to cool your components, is the most important part of the entire kit. As water passes through the water block it picks up heat from the processor, but without a way to cool the water, the heat would build. It takes a little longer but the end result would be like running a traditional CPU cooler without a fan or any internal case air flow.



While the radiator makes heat available to the outside air, a fan still has to get the air out of the radiator. The design of the radiator directly relates to the type of fan used. If the cooling fins on the radiator are tight together, the fan has to be able to push past all of those restrictions. If the fins are farther apart, the fan can spin slower, push less air and the end result is making less noise.



Pumps for water cooling systems come in all shapes, sizes and intended applications. It has been debated repeatedly as to whether or not a pump that moves water faster is better for cooling PC components. This is one of the best points of buying an all-in-one kit system; the pump is made for that system and end users don't have to guess on the amount of flow needed.



The more water or coolant in a loop, the better! The component used to store idle coolant is the tank or reservoir. As coolant passes through the block, it picks up heat which raises the temperature of the coolant. Most of the heat is dispelled through the radiator, but a small amount of is retained in the coolant. The more coolant you have in the loop, the less the temperature changes as the overall volume is able to absorb the heat and disperse it over a larger area.



The tubing that Thermaltake uses for their ProWater 850i is a UV reactive type that is 3/8 inch in diameter. When used with a black light, the tube reacts and gives off a green glow.



The ProWater 850i includes a 500cc bottle of Propylene Glycol, an industrial coolant that is less toxic than standard antifreeze. It is important to remember to NEVER USE TAP WATER in your cooling system. Tap water contains many contaminates that will eat away at the copper in the base and aluminum radiator. Even with distilled water, the water will cause a chemical reaction with the copper and aluminum causing your system to become less efficient.


Thermaltake has products in every store that sells computer components, and is one of the largest manufacturers of computer accessories. The 850i is a new kit; currently the system is available from just a couple of e-tail locations, but the list is growing. The MSRP of the 850i is set at 149.99 US Dollars, but I was able to find the kit for as low as 119.00 here in the US.
