I recently bought an HP Omen 2 months ago. For the last month it has made a glitchy noise that can also sound like grinding. It espicially happens when I watch videos of any kind, or if I am just on the web. Strangely, it stops making the noise when I play a video game such as overwatch. I know for a fact that it is a hardware problem as I have performed tests. It has something to do with the power or the fan. It changes loudness when i change the power settings. Is this Normal? I would appreciate if I got an answer ASAP. Thank you in advance!

The issue you're describing is most likely coil whine. On my Envy x360, the coil whine happens when CPU is in idle mode. So it can be heard in quiet rooms. Luckily it doesn't happen under CPU load. On other systems, like yours, the whine happens under load. Not much can be done on laptops. You can alter Windows power management modes to hopefully avoid which power state that the whine occurs on your system.

Yesterday I did some tests with other Omen laptops and it has the same coil whine. I'm don't worry anymore. The warranty will don't solve it.It's not a defect.Except if the coil whine is too loud, in this case. It will be better send the unit to warranty
All laptop brand has this coil whine(HP,MSI,APPLE,ASUS etc!!)
Keep calm, You should don't worry about it.
