So, one of the fans turns on to full speed at power on and it stays on. I've updated my BIOS/UEFI to the latest that Lenovo provides and there's no options for fan control or cooling policy. SpeedStep is enabled.
I ran sensors-detect and it doesn't find any pwm devices, just i2c-dev and cpuid. pwmconfig says "There are no pwm-capable sensor modules installed."
This is a i5-9400 (coffee lake) CPU with a B360 motherboard.
When booting into Windows 10 (out of the box), this doesn't happen. Like sysfs, device manager sees some fans but no pwm. SpeedFan (third party) doesn't see any pwm. There's only one third party tool that I could even get to see the RPM of one of the fans (HWMonitor from CPUID.) However, Windows must be doing something because the fan drops to nearly nothing while idle, which never happens on Linux.
Later on, I switched to intel_pstate=disable acpi=force because cpupower able couldn't to see my frequency or governor policy. It seems to have no impact on the problem at this point except for getting cpupower to work.
I'm really not sure where to go from here. I've been looking at thermald and I plan on learning how ACPI works but for now I'm not sure what else I can do. Any help would be appreciated a lot. The noise is quite irritating.

Update 1:
I just updated the microcode from "sig=0x906ea, pf=0x2, revision=0xb4" to "sig=0x906ea, pf=0x2, revision=0xca" (the latest) and it makes no difference.

Here's my dmesg http://ix.io/2cCD
I noticed the following
[ 3.588141] thermal thermal_zone2: failed to read out thermal zone (-61)I wonder if that could be what's causing this.
