The fan speed is constant and can't be changed 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 fan 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 PWM control whereas higher models do. I replaced it with a (Gigabyte) RX-560 which 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.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
