AP181 modded fans, static pressure affected?

Hi all,

I want to cut off the grills on my Silverstone AP181 and run them 'exposed' over radiator in a pull config.

As far as I understand, the grills are used to channel airflow.

However, does this mean that there would be any significant hit on static pressure of the fan?

Thanks

You could buy the FN180 and save cutting up a fan, that way you would find out. Personally I don't think the grills help, I think they cause more restriction.

There is only one way to find out

static pressure is a function of the fan blade design and the power of the motor. for a rad fan, you'd be better off ordering the AP182 since it has a stronger motor in the 1st place. cutting the grill simply ruins a perfectly good AP181. it would not improve the static pressure of the fan since it's running on the same fan blade and the same motor.
