Comment= # 7 on bug 97556<= /a> from Dimitrios Liappis 
To close the loop with my issue here, it appears that the Asus=
 Radeon RX-550
doesn't have any PWM control. The fan speed is constant and can't be change=
d in
Windows using the GPU Tweak II software either. A curious bit is that while=
 the
socket for the fan connector has 4 pins, only 2 are actually driving the fan
(however, I have owned graphics cards before that were able to adjust the f=
an
speed by adjusting the voltage using just the two +/- cables).

After discussing with Asus Support and the shop where I purchased it from, =
we
came to the conclusion that all 550 series cards in the market don't have P=
WM
control whereas higher models do. I replaced it with a (Gigabyte) RX-560 wh=
ich
is very silent. `sensors` now shows the RPM for the card. My understanding =
is
that all models starting with 560 onwards support fan control, regardless of
the manufacturer.
