CPUfx Z4 Watercooling Kit review


Some of you might remember last year when we tested CPUFX's Z3 watercooling kit, the predecessor of what we have in our hands today, a much redesigned product comes in the form of CPUFX’s latest offering, their Z4 intercooler watercooler.

Among some of the most significant changes from the Z3 design we have an inline 12v pump, significantly redesigned copperblocks and new radiator fittings, guess those were all the parts in a watercooler ;-)



The Radiator

Pictured above is the radiator, it’s basically the same as before though the fittings are bent 90 degrees to allow it to be mounted in the top of your PC's case as shown below. Included is a quite loud 120mm Sunon fan glued right onto the radiator and designed to suck air through it. You have the option of buying the radiator with a quieter fan however it would have been better if the fan had been screwed on to make it easier to change if needed to.

Having the fan to suck air creates the most noise; if you want to mount it in the top of your case that is the only way, if you want it to move the air in “the right” direction, i.e. hot air goes up. However, you can also place the fan under the radiator, thus making it blow air through the radiator, this silences the setup quite a bit, but also much harder to install I might add.

During the tests, there was no difference in temperature either way the fan was mounted, so if you prefer a quieter setup you will want to consider placing the fan on the other side of the radiator.

The reason for it being so loud when mounted to suck air is because the fan blades will be just one or two millimetres away from the radiator fins, creating turbulence, this distance increases when you mount it as I explained above but you can further lower the noise by placing washers in-between the radiator and fan.


Without doubt, one of the most impressive features on the Z4 is the inline 12v pump, rated at an impressive 180 Gallons per Hour; this device gets the job done well. Compared to the previous pump in the Z3 watercooler, this pumps water about 25% faster than its predecessor, impressive number indeed.

Unfortunately though, this comes at a cost, and that is in both terms of heat and noise; compared to the Z3 110v pump this one is very noisy, and also needs cooling. I solved this by placing the pump right under the radiator, though this lowers the cooling potential of the rig, having hot air blowing through the radiator…
