Alphacool NexXxoS Cool Answer 240 D5/UT Set CPU Water Cooler Review (Page 8)

Test System Setup

I would first like to thank ASUS, InWin, Corsair, and Fractal Design for supplying products for me to test with.

To see our testing methodology and to find out what goes into making our charts, please refer to our CPU Cooler Testing and Methodology article for that information.

Thermal Results

While not quite a chart topper at the stock settings, we are within a degree of the Nepton 280L. We had the pump at 4800 RPM for all testing as slowing it offered no thermal benefits. Something else to consider is that we have 1200 RPM fans voltage limited to 7.5V here as well. Considering what is cooling the radiator, we find this to be a great result.

Again, we did not quite make it to the top with the overclock applied to the system. However, these results are fan limited. Considering what you are about to see in the audio charts, to get into the top four spots with two fans pushing little static pressure and about 80-90 CFM between the two of them, this 68.66 degree result is impressive.

Noise Level Results

At 7.5V, the NB-eLoop fans were spinning near 850 RPM, drastically reducing what little CFM and pressure these fans are capable of. Even so, the system is barely audible, and at this point, we could hear the hum of the VPP655 over the 26 dB reading we got from the back or outgoing side of the radiator.

What is truly a blessing is that while it competes with the large assembled coolers, it is six slots down to the Larkooler, which is much louder than the Alphacool was, and it's eleven slots to the first AIO, and it isn't one in the same level as this is. Silence is golden with thermal results this NexXoS set offers.
