H5 Flow stock fans really loud?

Hello, i bought a prebuilt PC about 5 months ago, and the fans have been incredibly loud even under little to no stress. I have attempted to lower the RPM during lower stress levels and that definitely helped but the noise is still way too much while gaming.
So I wanted to ask if this was something others have experienced as well with this specific model and if there are any good solutions.
and if it's just how the stock fans sound I would like to ask for some replacement recommendations that would fit this case.
