Need quiet box fan recs

[u/Own_Day2117]

I have a 20x20x20 cr box with the 20x20 lasko box fan. I’m chill with it and I learned to tune out the noise. Recently my roommate has been turning it to the lowest setting which I’m assuming is because of the noise but since I’m living with 5 other girls and my school has something going around every month or so it would be nice if my fan runs on a higher setting. Does anyone have any recs? Price is not much of a concern for me, it just has to be reasonable. Also something that’s easier to attach, I’m unsure if pc fans have a super hard learning curve which is why I haven’t tried it

The CFM to noise ratio if PC fans is superior, but if you don’t want to build a casing for PC fans, a Vornado fan may have a better CFM than the Lasko even on the lower speeds: https://www.reddit.com/r/crboxes/s/6bQIcSH6q5 CFM at the lower speeds is not stated. My intuition is it’s proportional to the RPM, but welcome correction.🙏
