BTW

Alex, is this the same problem?
My card never was below ~32 W (even with single monitor
but I have two identical HDMI 1920x1080)
PSTATE_xxxx is much higher than Martin's
didn't saw "zero fan" / zero core (no spinning fans)

GFX Clocks and Power:
        300 MHz (MCLK)
        300 MHz (SCLK)
        600 MHz (PSTATE_SCLK)
        1000 MHz (PSTATE_MCLK)
        750 mV (VDDGFX)
        32.17 W (average GPU)

GPU Temperature: 31 C
