Hi, When using more than one monitor, the card uses higher clocks than in single-monitor mode and low-power profile. As a subjectively negative side-effect, the fan on the card starts making more noise. Other cards I used before had no problem with staying quiet even when more monitors were attached. As soon as I switch back to single-monitor mode, clocks go down and the card becomes silent again. Is there a way to manually force lower clock speeds, and therefore reach an acceptable noise level? Maybe make it use the same power profile settings in dual-monitor as in single-monitor?
It really depends on what kind of power profiles the device exposes. Boot with drm.debug=0x2 and they'll be in dmesg.
