*set as low as possible to maintain target GPU temperature on load.
CPU fan at 50% (1000 RPM).
Ambient temperature: 24°C.

For loading testing, the Noctua NH-L12 heatsink's 92 mm fan was set to 50% (1000 RPM), a speed that provides a decent amount of CPU cooling without having a large impact on the noise level (it measured just 16 [email protected] at this speed). Of the system fan speeds tested, the 60% level delivered the lowest overall sound output with our testing parameters (adjusting the GPU fan speed to maintain a 85°C GPU temperature at 22°C ambient). At the 50% level, the stock fans were fairly ineffective, requiring a much higher GPU fan speed, and causing substantially higher CPU and motherboard temperatures. The 70% and 80% settings ultimately created more noise than they saved.

On load, the system sounds almost as it did during the baseline tests. The CPU fan was set to a higher speed but its smooth profile made it inconspicuous. I'm not sure if the power supply fan spun up from its minimum speed, but its contribution went unnoticed. The GPU fans made the most impact but they sound fairly good spinning only 160 RPM faster than the minimum. It also helps that they were positioned on the opposite side of the microphone. The machine measures 1~2 dB higher on the other side.

CPU fan at 50% (1000 RPM).
Ambient temperature: 24°C.

Removing the impedance caused by the filters resulted in a moderate increase in thermal performance. Using the same fan speeds as the best result achieved earlier, taking the filters out of the equation allowed temperatures to drop across the board, with the most noticeable improvements being a 5°C and 6°C decrease for the CPU and GPU respectively. The system fans can thus be slowed from 60% to 50% and the GPU fans can be turned down from 43% to 40% while maintaining the same GPU temperature standard, for a net noise difference of just 1 dB.

The best result I could achieve with the case in horizontal position was 31~32 dBA, with the stock fans at 80% and GPU fans at 53%. It was significantly louder than the vertical orientation as the fan vents become more restricted. Even with the filters removed, much higher fan speeds are required to attain a similar level of cooling.

Considering the relative size of the FTZ01, its performance is impressive. Though substantially louder than our Mini-ITX Gaming Build using the BitFenix Prodigy, that system was tuned to achieve the lowest noise level possible. The higher fan speeds required to attain a similar amount of CPU/motherboard cooling may result in the noise difference being cut slightly.

Fractal Design's Node 202 is actually more similar to the FTZ01 than any other competitor, though it is smaller, but its performance is far worse, hobbled by poor ventilation and a lack of fans. It could not operate the ASUS Strix 980 at the target 85°C temperature, and in fact failed to keep the card from throttling, even with its fans going ballistic. Ditto the fan on the smaller CPU cooler, which explains the very high 41~42 dBA @1m SPL.

Also plagued by airflow problems, the Enthoo Evolv ITX was 4~5 dB louder and hotter by double-digits inside under the same test parameters. Even with its entire front panel ripped off, it doesn't quite match up to the FTZ01.
