Cyberpower Hyper Liquid 100 GTX 1080 Gaming PC Review

Acoustic, Power & Thermal Performance

Acoustic Performance

During idle usage scenarios, the Cyberpower Hyper Liquid 100 is relatively quiet and you should be able to accumulate to the noise levels really quickly. Of course, I wouldn’t classify it as silent and this probably stems from an audible noise emanating from the pump. Under load, the pump’s output doesn’t really change and the additional cooling relies on the fans running at higher RPM values. Rather strangely, the fans tend to behave in an erratic manner and employ an aggressive fan curve. This makes the changes in fan speeds much more noticeable and I can’t fathom why this is the case. It’s almost difficult to describe how suddenly the fan speeds change because it happens so often within a tiny time frame. Hopefully, this is down to a PWM issue in the BIOS and easily fixed.

Power Consumption

Modern PC components even at the higher-end tend to be extremely efficient and have a low power draw. As you can see, the total system power consumption barely passes 210-watts which is astonishing. To be honest, I expected the power consumption to be higher given the CPU overclock and GTX 1080. Oddly, a competing system sporting an i5 6600K uses more power. Why? I’m not entirely certain; it could be a result of the overclock’s modest voltage or simply variation within the AIDA64 stress test.

Thermal Performance

The custom water loop easily contends with the 4.4GHz overclock and the load temperatures hit a maximum reading of 81C. Additionally, the average thermals once stressed was 76C which remains well within the i7-6700K’s safe limits. Also, the graphics card’s vapour chamber cooler is effective and prevents the maximum temperature from surpassing 85C.
