9/2/2023 0 Comments Dell fan control laptop![]() ![]() Starting in 2021 (Tiger Lake systems) they removed the old interface that HWiNFO and other tools that can deal with Dell fans were using, so WMI is the only way to go now that I am aware of. ![]() I think any Dell system from 2018+ (maybe older), desktops included, supports the same WMI interface for reading the fan speeds. I did a lot of slinking around Dell's libsmbios C code (for Linux SMBIOS support), a lot of BIOS token/variable dumps, and some reverse-engineered Dell Power Manager code to figure this out. I am author of Dell Fan Management and I would be happy to pass along any information to help with this implementation. I've updated all drivers and installed all updates on Windows Update.Hi I just noticed this thread. I can open Task Manager -> Processes and watch all the start-up processes raise the CPU load and the fans will speed up to the expected level.Īt 1 minutes and 54 seconds, a process called "Dell Instrumentation" will start using about 27% of the CPU and the fans will speed up to full and stay there, even after this dell instrumentation process goes down to 0% about 10 seconds later. When I boot up, the fans are running normally at first. ![]() ![]() When I shut down, the fans stay spinning at full speed right under the laptop powers off, where they immediately stop. Using Open Hardware Monitor, I can see the 4 CPU cores are at 43 - 53 degrees C, so this isn't due to overheating. I have the laptop set to use the integrated GPU instead of the dedicated GPU so the GPU is usually a 0% usage. I have an Alienware 14 laptop that I use mainly for web browsing that developed an issue a couple of days ago where the fan would be spinning at full speed regardless of how much load the CPU was under. ![]()
