Temperature And Sound Level

AMD FirePro W9100 Review: Hawaii Puts On Its Suit And Tie

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.

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:
