Temperature And Sound Level
Temperature Transients
We measure each card's thermal behavior at a constant 22 °C (72 °F) ambient temperature, at normal humidity.
To put the following diagram into perspective, almost every card we benchmark bumps up against its factory-set temperature limit.
Model | Idle | 3D Workload |
---|---|---|
Quadro K5000 | 30 °C | 76 °C |
Quadro K6000 | 32 °C | 80-82 °C |
FirePro W9100 | 40 °C | 92-93 °C |
FirePro W9000 | 34°C | 78 °C |
Measuring the Sound Level
We measure each graphics card's noise levels with a calibrated high-quality studio microphone (supercardioid) 50 cm away from a position perpendicular to the middle of the board. This distance, as well as the strong cardioid microphone characteristic, represent a compromise between avoiding noise generated by the fan’s airflow and ambient noise that can never be completely eliminated. Our noise-dampening efforts certainly help minimize the latter, but they'll never be 100-percent successful.
As we've seen many times before, reference-class cards typically achieve their cooling performance at the cost of higher sound levels. High-end workstation cards, in particular, exhaust waste heat from their I/O panels to avoid affecting other platform components. However, this is enabled through the use of a radial fan, and our results show that they're quite noisy.
Here are the detailed sound level readings:
Model | Idle | 3D Workload, Open Lab Bench | 3D Workload, Closed Case |
---|---|---|---|
Quadro K5000 | 30.8 dB(A) | 37.7 dB(A) | 37.1 dB(A) |
Quadro K6000 | 30.8 dB(A) | 42.7 dB(A) | 41.2 dB(A) |
FirePro W9100 | 33.5 dB(A) | 51.3 dB(A) | 49.8 dB(A) |
FirePro W9000 | 33.2 dB(A) | 55.4 dB(A) | 52.7 dB(A) |
