Whats a good RPM to set my 6 fans to?

I use Corsair iCUE so id like to set my RPM through that. Im asking this because I want to set the RPM as low as possible so I dont hear the fans through my headset without overheating.

That number is going to be based on the diameter of the fans and the shape of the blades.  For 120 mm fans it used to be somewhere around but usually above 800rpm.  For 140mm fans it was more like 500 than 800. It sounds easy enough to test.  They’re your ears after all.

For 120mm fans I like to have them around 1200 rpm. The ones I have are not too loud and get the job done (Noise is noticeable, but my headphones cancel it out when I'm playing).

 

Edit: This was for a 3 fan set up, so you can probably get away with a lower RPM for 6 fans

Play around with it.  Check your temps.  The deal is fan noise is not completely linear with rpm.  There’s a drop off at the low end.  There’s a point below a certain level where a fan makes almost no noise at all.  It’s based on the speed of the tip of the blade.  This is why smaller fans can spin faster and still avoid it.  It’s possible that effectively silent speeds won’t push enough air for you.

it depends on the case and fans. 120mm fans should be pretty quiet up to 1000rpm. I'd bet that you won't hear them up to 1200 with a headset, unless the case is very restrictive, or something in there resonates with that rpm.
