Like many other kits available, the innovaCOOL rev3.0 uses an in-line cube radiator. The in-line radiator consists of a looping copper coil with thin aluminum fins in aluminum housing. Unlike the multichannel radiators, the water in the in-line radiator have one path to follow, and thus this restrict the flow quite a bit. Generally speaking, of course.

The waterblock and its retention mechanism is, in my opinion, one of the very best available when it comes to user friendliness. The waterblock is a chunk of aluminum measuring 50x50x32mm with a copper core inside. This copper core seems to be a cylinder that has fins milled into it to increase surface area and thereby efficiency. The cylinder shaped core should also provide proper turbulence, which is an important factor for increasing efficiency. Quick-connect fittings are used to make for fast and secure connection of the hoses.

The retention mechanism can only be described as ingenious. The construction is so completely different from anything I have seen, simple yet solid. It uses all of the lugs on the CPU socket, and no matter how I tightened it using my fingers only, it would not break the socket lugs off.

The reservoir is also something entirely new. Usually, we see these grey electronic project boxes or some sort of custom made aluminum reservoirs, that are rather big, with the pump inside the reservoir. Innovatek has a different take on it – they made their reservoir out of a small piece of aluminum that you actually hook up on the intake of the pump. There are rubber seals around the intake and the yellow plastic cap on top of the reservoir to prevent any leaks.
