At CES 2008 we could see the complete range of current and forthcoming water-cooling products from CoolIT, including the prototype of a water-cooling solution for rack-mount servers. Check it out.
The simplest product from CoolIT is called Pure. This water cooler is sold pre-assembled, not requiring any kind of maintenance or assembly by the user, being targeted to users that want a quiet PC and even overclockers that don’t want to go through the hassle of building their own water-cooling systems and/or want a cheap water cooler. According to CoolIT this product has a MRSP of USD 125, but we could find it being sold around USD 105 on the internet, which is a very affordable price for a water-cooling system.
As you can see on Figures 1 through 3, this cooler comes with everything already assembled: radiator, 120 mm fan, pump with embedded water tank, CPU block, hoses and liquid coolant already installed. As you can see this system is connected to the power supply through a standard peripheral power connector. It fits both AMD and Intel CPUs.

[nextpage title=”Freezone Elite”]
If you want the convenience of a pre-assembled water-cooling system but the performance of a high-end water cooler, then Freezone Elite is the product you are looking for. It comes with CoolIT’s MTEC Control Center, allowing you to monitor and control the water cooler through Windows, using CoolIT’s software or NVIDIA’s, as this system is ESA-compatible (click here to learn more about ESA).
Freezone Elite features six thermoelectric coolers (TEC), also known as “Peltier,” on its radiator. If you pay close attention in Figure 5 you will see that this cooler has two water blocks fastened to the radiator (the blue parts), one on each side, and three TEC’s are available between each block and the radiator, providing extreme performance to this cooler. Keep in mind that these devices are the same one used by some drinking water and beer coolers, so they make the two water blocks to work like two small refrigerators.
This cooler is also compatible with both AMD and Intel CPUs and like Pure comes with an aluminum CPU block.
The only problem with this cooler is its price: according to CoolIT it is quoted around USD 450 – almost four times more expensive than Pure.

[nextpage title=”Reference Series”]
Reference Series is CoolIT water cooling solution for video cards, available for ATI Radeon HD 2900 and 3800 series (called AT version) and NVIDIA GeForce 8800 series (called NV version). Like the other CoolIT products this one comes pre-assembled, not requiring any kind of maintenance. Of course you will have to remove the original video card cooler and install the cold plates that come with the product by yourself. Both versions come with two cold plates to cool down two video cards in CrossFire or SLI modes. According to CoolIT this product will have a MRSP of USD 299.00.
The cooler itself is a box that uses two 5.25” bays from the computer case, with two hoses coming out of this box and being connected to the cold plates.

The cold plates for each series are completely different. On the AT version the plates are made of steel, while on the NV version the plates use a copper-made base and thermoelectric coolers (TEC, a.k.a. “Peltier”) between the water block and the copper base, making the water block to work as a refrigerator. If you look closely on the pictures below you will notice that the plates touch the memory chips, cooling them down.

[nextpage title=”Boreas Case”]Boreas is a custom-built < a href="https://www.silverstonetek.com/products/p_contents.php?pno=tj07" target="_blank">Silverstone TJ07 case containing CoolIT’s Boreas water cooler, one CPU block, two video card cold plates (identical to the ones used on Reference Series, see previous page) and a MTEC Control Center (see Figure 6). This is the most extreme cooling solution from CoolIT, providing the extra performance required by extreme overclockers.
This system also comes pre-assembled, requiring no assembly from the user besides the installation of the video cards cold plates.
In Figure 14, you can see the custom-made Silverstone TJ07.

In Figure 15, you can see the Boreas cooler installed inside the case and on Figures 16 and 17 how it looks like outside the case. This cooler has 12 thermoelectric coolers (TEC’s or “Peltier”), three under each water block. The two fans pull hot air from inside the radiator to the outside, so air flows from inside the cooler to the outside.

[nextpage title=”Rack-Mount Server Water Cooler Prototype”]As we mentioned before CoolIT presented the prototype of a water cooler system for rack-mount servers. Data centers use powerful air-conditioning systems to cool down the room temperature and thus indirectly control the temperature of the servers. The idea of using water cooling system is to cool down the server temperature to a level that the need or air-conditioning is drastically reduced, making data centers to save on the power bill. CoolIT estimates between 20% to 30% power reductions on data centers if water cooling solution is used.
In Figure 18, you can see the rack prototype closed. The system provides controlling and monitoring through a standard Ethernet port, so you can monitor and control the water-cooling system from anywhere inside your network (the laptop on the prototype is doing this).

With the rack opened (Figure 19) you can see that its door is in fact a huge radiator with two huge fans.

In Figure 21, you can see the rear side of the rack. The hoses and connectors used are industrial grade, used for years on standard hydraulic applications.
