if it's louder than this:

woooooooooooooooooooooosh

then it's too loud.

Ex. if it sounds like this:

vroooooooooooooooooooooom

it's too loud.

I run the fan on my GPU at 100% all day and the fans on my laptop at 6K RPM, so as long as I can cover it up with the sound of my radio when falling asleep, I'm fine

My personal preference is around 1500-1700rpm.
So, I voted 1700rpm.

i would rather have more cooling performance/airflow than being annoyed by a woosh tbh.
besides my computer is not 2 inches from my head

This is sort of a silly question. Ive got a fan in the front of my case that has like ten fins and spins at 900rpm, and it pushes roughly the same amount of air as my back exhaust fan that has 4-5 and spins at 2000, theyre both almost identical in noise output, the only difference is the ten-fin is a deeper hum.

I see a closer correlation between CFM and noise output than RPMs and noise personally.

I think it's going to be difficult for you to get an answer based on RPM. For example, my only experience has been GentleTyphoon AP-15s, which run at 1800RPM very, very quietly.

That's the exact thing. It varies from person to person, and also from fan to fan, and location to location, etc.

Heck, it can also vary with the same person! Me, for instance! Couple years ago I was working on my Master's degree and I needed my system to be really quiet. Thus, I kept 120mm fans at around 800RPM or less. Since then, I'm fine with 120mm fans at 1200RPM since I don't need the silence anymore.

I would have said 1200RPM was a decent level before but now that I'm trying to silence my computer I would have to say 1000RPMs or less. I'm going to a very quiet machine. If it wasn't for a quiet machine then I would say around 1400-1500RPM would be a good range.

I have a idea corsair.

Make your fanspeeds variable on the fly.

Then you can keep everyone happy
