I have a new Omen 870 desktop. There are no dust or clogged fan issues with the machine, brand new.
I replaced the stock fans with Noctua fans to help keep the noise of the machine down, as it is being used in an audio production environment.
Every time I boot up, I get the blue screen telling me there is a system fan error and that the machine will shut down in 15 seconds.
The hottest I have seen the CPU via Omen Control and SpeedFan is 60 degrees during an audio project render.
Generally, it is in the 34 degree region.
I would suppose that the main extractor fan at the back of the machine is running a tad fast. Quiet, but I do feel quite the intake of air on from the side panel vent.

The motherboard monitors the speed (RPM) of the "chassis" fan and the "system" fan, unless you have used BIOS SETUP to *NOT* do that monitoring for a specific fan.
Within BIOS SETUP, does it report the actual RPM of the system fan?
Is it "out-of-range" -- too slow, which the motherboard interprets as "failing" ???
Does the fan have its own RPM-control? Can you turn it up a bit?
There are labelled connectors on the motherboard for each of the 3-wire (or 4-wire?) fans.
Be sure that you have connected a replacement fan to the labelled "system" (closest to the CPU) fan.
If you reinstate the system fan, is the message still generated?
Is your issue that the microphones are picking-up the fan-noise, or that you are hearing the fan-noise while listening to the monitor speakers?

Thanks for the reply.
The RPM of both fans are in the 1000 region.
I do not have an option to disable fan monitoring on the F10 BIOS config.
The fan does not have an RPM control.
System fan, a 3 pin, is placed into the System Fan 1 plug.
The CPU fan, a 4 pin, is placed in the CPU Fan 1 plug.
I am going to swap back to the original fans to see what RPM they go at.

I plugged the only system fan back in and the error stopped.
There is no significant difference, or indeed any difference at all, between the RPM of each fan.
The only observation I can make is that the Noctua fan takes a second longer than the original fan to spool up. By the time the error message pops up, the system fan has just got going.

Is there anything else that can be done here?
I get the sense that the case fan is running at a higher speed when there is a fan error on boot. I cant find any way to bypass the fan error.
I cant see myself being able to put more money into the machine with fan controllers and all that messing around, so I may end up selling the thing!

Probably not. This is a "user-to-user" forum, although some of the participants are employed by HP.
Since reverting to the stock "system" fan has eliminated the symptom, how much louder is the HP fan compared to the other fan? Can you do something to muffle the noise it generates? Egg cartons as sound-baffles?
