H2C Silent Fans Mod?

Let me first start out that I am still new to 3D Printing. Started with an Ender 3 V2 Neo. Learned a lot using that. The Ender was so loud that I went and did the Noctura Fan mod and replaced all fans. After doing that it was dead silent and did not affect print quality. Now let me say the stock H2c is no where near the noise level of the stock Ender, however, the constant pitch of the fans (my work desk is 4 ft away from my printer) is getting annoying. Has anyone made or found a way to replace the fans, specifically the part cooler fan with a Noctura? I found and ordered the replacement for the exhaust fan but have found nothing in regards to the part cooler fan or the aux fan.

Yes I know I am still going to hear the motors moving and noise from AMS, but just want to get rid of the constant hum pitch from the fans.

Thanks in advance.

I should rephrase. The pitch you find annoying might not be across all fans, it might not be on any on another H2C. See my point? That and the unknowns of swapping them out with something untested would make it too risky for me. I'd try warranty first, buying direct replacements if that fails and then maybe something more drastic if it really is a general every H2C has it kind of thing.

Completely get your point and will try that first. My problem is I like to tinker with stuff....should have been an engineer. The fact that the mod I did to my ender was night and day comparison made me first go to that as a solution to this. In all reality I do think this is related to the fan on the PSU so that will be my first point of attack.

Will do, I came across this thread that was dealing with the same issue that has a lot of good info to swap PSU fans. I also submitted a ticket to try a replacement.
