HP Omen 15 2019/2020 Laptop Loud Fan Noise [Solved] Power Settings in old Control Panel

[DigitalDomain]

I think I found the solution to the Fan Noise problem on HP Omen laptops. I got mine back in 2019 and always had desktop replacement laptops and gaming laptops throughout the years making websites, music, gaming, video editing, graphic design and everything else so I assumed the fan noise was normal for so so long... It's when you're not doing the CPU intensive stuff that you notice the fan being loud and it's most annoying so why on Earth does it sound so loud if you're not doing anything intensive...? So I assumed fan noise was normal until I used some MacBooks and other PC laptops with much lower fan noise the last year or so, even when just browsing the net and doing non-CPU intensive tasks. 

The BIOS updates don't matter as much in this case, although one of them was dodgy and I did downgrade, not sure which version I'm on now but regardless, it's more to do with these types of over-clocked laptops and an interesting setting in the old Control Panel for Windows 10/11 under System & Security / Power Options.

STEPS

Open Control Panel. Press the Windows Start button and type "control" and you'll see Control Panel pop up.

Go to System & Security / Power Options. 

Click the power plan you're using, such as "HP Recommended" or "Balanced", and select the text link to "Change plan settings". Then click the text link "Change advance power settings". Now you'll be presented with a dialog box that shows power settings for the whole laptop.

Scroll down to "Processor Power Management". Make sure "Minimum processor state" is set to a low number! It was set to 100% on mine! This caused the fans to be on loud all the time and you'll notice in the CPU GHz is always up around 4GHz when it's set to this on the minimum setting. Set it to 5%, like in the screenshot below. 

The "Maximum Processor State" is also useful to prevent your laptop from using too much CPU even when running big software apps like Adobe Premiere Pro, Ableton, Blender etc., it can limit their CPU usage to keep fan noise low so experiment with the maximum. I have mine set to 85% but 70% would keep the fans quieter under larger loads because it will stop the laptop from getting too hot, overclocking. You'll notice the CPU clock rate goes down to 1 GHz or so and only increases as it needs it. 

I up that to 100% when I want to render a video or do some gaming or something that needs the extra power. But for most tasks these settings are perfect. See screenshot below and copy it. My laptop is so much nicer to use now!  

Hopefully this helps a few frustrated HP Omen owners out there like it did for me 🙂 

Other things you might want to do to prevent unnecessary CPU usage and fan noise is end the processes Omen Gaming app, it uses far too much CPU usage for what it does, must be badly coded. Your keyboards lights will stay the same anyway.
