Loud power supply

[bblakek16]

So i've had my motherboard, power supply, and radiator just sitting on my desk for a while as i waited for my case to arrive and my nex750b supernova was near silent. But now after i installed it in my mastercase pro rgb i noticed my computer was just loud and i didn't know what it was so i unplugged every fan i could to where only the gpu and power supply fans were running and i knew it was the power supply. It isn't loud but its definitely noticeable and very obnoxious. Is there any fix for this i've read online that some peoples are very quiet and some are very loud i just want to know if there is a fix since i don't want to go through RMA'ing it since i need a computer for school and cant go a week without one. Thank you for reading i hope somebody has a fix for this.

Swapped my fan out. Extended the signal wire to monitor speed.

i would do something like that but its brand new and i don't want to void the warranty
