Helios 500 - Weird fan noise on auto

So when the fans are on auto mode and the pc is not heavily tasked, the fan noise is on the quiet side but it's disturbingly irregular and accompanied by something like coil whine, making it even more annoying. When i set the fans to manual mode, and even set the RPM's to what it was on auto mode, the annoying sounds are completely gone and it sounds perfectly normal.

What could be the cause of this? Software problem? Anyone else has this?

I also noticed that fans could also spike to max and then suddenly drop when temps slighty start to rise. Seems like fan software could use a lot of polish, not to mention it lacks an option to set a manual fan/temp curve. This is really weird on such a machine. Other than these i've been perfectly happy with this laptop.

    Khelgar Coil whine sounds are pretty common on any electric device some are louder that others and others arent even noticeable at all sometimes its coming from the chipsets some may even come from the ssd itself or even the fans regarding the fans rpm spikes its normal when coolboost its on when theres temp spikes the fan curve its built into the bios advanced options and cannot be changed the bios are all locked on all acer laptops PS its just basically a bios UI to some of the hidden functions allowed for the end user to control here is just an ex of the fan curve on the H500 intel variant
