Upgrading to a "better" fan on Noctua NH-L9a AM4?

Just out of curiosity, might even need this info later on, would adding a bigger fan to a Noctua NH-L9a heatsink make even a slight difference? I was looking at a bequiet! Silent wings 2 92mm fan which has higher air pressure but slightly lower air flow and its 25mm height compared to 15mm on the noctua one.

Higher air pressure won't really help.

The silent wings will probably be quieter though.

Higher airflow fan then? Still the same question.

Yeah more airflow.

Make a few degrees improvement.

You can't compare one manufacturer's test measurements to a different manufacturer as the testing methodologies differ, however, I would expect a 25mm thickness fan to improve over a 14mm one. I would go with the Noctua NF-A9 PWM which increases the static pressure to 2.28 mm H2O from your current fan measuring 1.64. Don't expect miracles,though. That heatsink is pretty small. I would contact Noctua and ask them how much improvement you could expect.

 

You don't have space for a larger heatsink?

The NF-A9 has been used on the NH-L9i without much improvement on temps. I'd expect similar results with a SW2.
