![]() If your GPU fan doesn't spin during this process, it indicates a problem.Ī second method is to put your GPU under a stress test. On boot, your system usually runs all your fans at full speed for a brief moment to check that they're working. First, restart your computer and watch your GPU fans. This because it's a waste of energy for the GPU fans to constantly spin if the temperature of the card is already low. It's common that GPU fans don't spin unless under load (meaning you're doing something intensive on the system, like playing a game or rendering images) and the card reaches a specific temperature. Test the GPU Under Heavy Loadīefore proceeding to any further steps, you first need to check that your GPU fans are meant to be spinning.

If yes, how can I figure out what’s holding it back?.Where do I need to poke to get the installed system to find the correct fan sped sensor readings (must be possible since live Manjaro can do it).…and just to make matters more interesting, I also tried setting this up on a live openSUSE USB, and it also found the fan speed but claimed there was no PWM control device available – while still being able to switch fan speed up to 100%. This means that the sensor configuration has changed a few times, and there may be some leftover data from the removed hardware causing issues. In the course of pinpointing the issue (there was also something wrong with the RAM configuration, also causing crashes, which obfuscated a lot), I have swapped graphics cards a few times, and also recently replaced the motherboard on the same system. On the live image, I can see how the fan speed ranges from 0 to 1000/min before running pwmcontrol, depending on temperature, and goes up to 3400 afterwards. That is: it manages to turn them on or off, but not to ramp in between the extremes, so it stays at 100% during the auto-detect phase, until I use ctrl+c to abort (and then the fans stay at 100% until the next reboot…). Unfortunately, it then fails to auto-detect the pwm setting at which the fans stop spinning. I thought that this might be an issue with the fan speed sensor (either directly, or due to it not being supported in some way), but when I boot from a live USB image (also Manjaro), the fan speed is detected and indicated without any issues, and the setup in pwmconfig continues. The fans then keep spinning at 100% until I reboot the machine. When I then run pwmconfig, it starts by spinning the fans up to 100%, (very audibly),īut the fan speed sensor stays at 0, and pwmconfig aborts. I have the case opened, and the fans are indeed not spinning. ![]() While trying to find the issue, I ran sensors-detect to find the temperature readings for the GPU, and it found the following:įan1: 0 RPM (min = 0 RPM, max = 3400 RPM)Įdge: +37.0☌ (crit = +110.0☌, hyst = -273.1☌) I have the following problem with my graphics card (Radeon 5500XT):īefore configuring anything manually, the fan speed was handled by the card, but did not exceed 1000/min, which lead to overheat problems (sure took me a while to figure out why games kept knocking out the machine, sometimes, but sometimes not…). ![]()
