A few minutes into stress testing, it was soon realized that the stock fan barely had to do any work to generate quiet results. Under our standard testing parameters (two threads of Prime95 combined with FurMark), the CPU fan running at minimum PWM speed was sufficient to keep the processor comfortable while the GPU fans only required a 250 RPM speed bump to maintain a 85°C GPU temperature. The resulting 17~18 [email protected] SPL was lower than the 19 [email protected] produced by the stock fan running at 60% speed during our baseline tests so it can't get much quieter.

Striving for an 80°C GPU temperature only cost an extra 1~2 dB. Adding a third thread of Prime95 (four threads interferes with GPU usage) made the CPU and motherboard heat up a few degrees more but the noise level was unchanged except for a slight increase when shooting for a GPU temperature of 85°C (the power supply fan probably sped up slightly to deal due to the warmer conditions).

Compared to our baseline tests, the acoustic quality of the system actually improved under load. The SPL is only slightly higher and the GPU fans emit more high frequency noise, helping balancing out the low-pitched hum of the stock fan.

A properly cooled system with our usual reference GTX 980 draws around 280~290W. Our HD 7870-equipped PC-Q10 enters this power consumption range when a third thread of Prime95 is added as a stressor, coming close to compensating for the difference in GPUs. With this equalizer in place, the noise difference between the PC-Q10 and competing mini-ITX cases we've recently examined is substantial. The black variant of the BitFenix Prodigy comes closest but trails by 2~3 dB. It's an impressive feat considering the PC-Q10 is much smaller and has just the lone case fan.
