I am going to replace my original 1U PSU's 15000rpm 40mm fan with Noctua 5000rpm 40mm fan to reduce the jet engine noise currently coming out of it.

Will that work fine or lead to any fire hazard? Since the airflow will be reduced by 1/3rd.

Please help me find a solution to reduce the PSU noise. I was creating a product with a compact PSU. And since it will be for a normal home use, I don't want it to create any loud noise.


Thanks

I wouldn't do that if I were you. The fan in that PSU is the sole reason the PSU is delivering it's advertised power. You could get a pair of headphones to drown out the noise or aim the PSU's back end towards some sound dampening material to absorb some of the noise and prevent reverberations.
