I am not surprised that the CPU cooling fan is throwing the startup error since it has a max speed of 1700 rpm. If the smaller fans are 3-pin, those should not throw the startup error. If you still have your OEM Dell CPU fan, connect that to the motherboard and get a successful, error free startup. Then switch back to your Vetroo fan and hope for the best. Go to Control Panel > Programs and Features . . . look for Dell Support Assist, select and choose 'Uninstall'
I have a Dell XPS 8940 that I purchased in 01/2022. The very first thing I did when I bought it was to upgrade the CPU cooler (ventroo V5) and add 2 Noctura fans and a BeQuiet PureWings2 80mm front fan. This greatly reduced CPU and system ambient temps. I've been running this setup for 9 months now with no issues. I recently upgraded the NVMe drive to a 1TB and did a fresh install of windows 10. Ever since I get the Dell SA (SupportAssist) running each time I restart the PC because it thinks I have a critical error with the CPU fan. My question is, what can I do to stop this? And why would this error not appear until I did a fresh install of Windows 10?I'm running bios 2.8.
