The fan rattle something that can be resolved by the Abschauben the front panel and change the setting to 25% fan speed but.
The card itself (Nvidia 970GTX) suffers but under the well-known Spulenfiepen problem. This is available at each card having its extent appears to depend 100% of the power supply - at least this can be seen from my own experience.
I have (with the Palit Thunder Master software) the GPU Clock greatly scaled down, which seems to eliminate the Spulenfiepen almost entirely. If necessary I can then increase again the clock.
