I have the power manager setting at "quiet", yet the fans still blaze at full speed. Yes, Dell Power Manager Service application has a Thermal Management option that help control processor and cooling fan settings to manage performance, system surface temperature, and fan noise. There NEEDS to be a utility or BIOS update to ALLOW Fan control on Dell xps 15. Also note that the fans' actual maximum speed may be higher than what you get if you set the speed to '100'. Dell Laptop Fan SettingsThe most frequent keys to access BIOS after. With the security modules enabled user-space programs cannot do fan control via ioperm mechanisms so you can submit a patch to the dell-smm-hwmon kernel module to whitelist pwm toggle command (more details in the link at kernel documentation). If I was just able to control the fan speed, I could turn this annoying garbage off, but every piece of software I've tried to use (hwinfo, speedfan etc.) cannot find the fans at all. Some systems have more granular fan control while the EC is in charge, but you cannot change the behavior other than picking a thermal profile in Dell Power Manager. However, the braindead logic still spins the fans up until I get frostbite on my leg if I so much as touch the keyboard or any button at all. It is significantly colder than my leg.ĭell's firmware clearly has some very stupid and simple logic behind it, which prevents the processor fan from spinning within a temperature upper limit (which I am probably 40deg below) if you don't touch the keyboard. After you download Speedfan, select Automatic fan speed to have Speedfan automatically control your system, or choose Configure > Advanced, then find your fan and set it to Manual. I cannot turn this god damn fan off, and it is making the laptop freezing cold. Then run: dell-bios-fan-control 0 in the Terminal to disable SMBIOS cools my laptop in s-tui and it even reads the fan speed now which. To control your CPU fan on Windows 10, try a third-party tool such as Speedfan. What annoys me to death is that there is seemingly no way to control the fan speed. The CPU is consistently at 2% and yet my memory usage is at 70% - this is intended, I am running docker desktop, multiple hyper-v vms and a WSL installation. Enable snaps on Ubuntu and install dell-bios-fan-control. They are running at full speed on the left side (the processor fan) - I suspect due to high memory usage.
