Noctua NF-A14 (140mm) at 550 RPM normal?

I just replaced my top exhaust for my NZXT H510 case with a Noctua NF-A14 (140mm) fan.

I left my motherboard fan settings to Smart Fan, and the Noctua is running at around 550 RPM at idle (system temp is at 35C or 95F)

My rear exhaust fan is still the stock NZXT 120mm fan, and that runs at around 930 RPM.

Is the Noctua running low because it is a larger fan?
Should I manually crank it up a bit?

 

My front intakes are the two 120mm fan on an AIO rad.

if the PWM% is the same, then yes

You could test, but ideally both should go faster.

Noctua NF-A14 PWM 140mm Blæser - 140 x 140 x 25 mm, 300~1500 RPM,

the operating range is between 300-1500 and is set via PWN. all low noise fans are running slower, but are still moving alot of air.

if you need more airfow yes you can raise it but at 35c your system is more than fine.

Fans usually have +-10% on the rpm range. I have 2xA15 on my CPU. Currently, when CPU is not used much, 1st fan is at 200rpm (today's low is 168rpm), 2nd is 0rpm. 2nd actually powers up only when CPU temp goes over 60C. I've had both CPU fans at 0rpm on some cold winter days. That actually lower than what spec says, but it works fine, so I'm not complaining. I also have 3x3pin fans running at 400rpm, 500rpm and 550rpm at idle.
