No point in buying PWM fans if they don't function. Before I consider replacing or adding more fans I'd like to figure out if there is a workable solution other than DC. 11 and later, the kernel boots up with the PWM. The stock Intel cooler for my i5 8400 and two 140mm case fans that came with the CM Master Pro 3 case are cheap but I don't suspect they are the root issue. I also cant access BIOS since mine freezes when I select any icon like the SCU(Topic for another thread). DC settings for the case fans work as displayed. The other three non-full speed options (Normal, Silent, Turbo) display considerably more realistic temp reactive curves which are disregarded in use for the same 98% base fan speed. Both case fans lock into 98% as the optimized, and now lowest manual, setting. In current BIOS this option is replaced by "Optimize all fans" which sets all fans to PWM > Manual. I briefly looked around before updating from the version it shipped with and seem to remember it allowed setting the PWM fan speed based on cpu/mb/HDD temp individually or as a composite. First build and the fan settings in BIOS seem strange.
