kaze maru installation

[n_slutzker]

I've purchased 2 "Kaze-Maru" 140mm case Fan - 1200rpm to install into my CM690. Please inform me on Air Flow orientation , so I'll be able to decide on installation as exhaust or intake.

sorry, but what did you realy mean? Airflow orientation of the fans? there is a arrow on the fans chassis. or what you mean?

[n_slutzker]

I posted this question because I was surprised that I cou'ld not find any arrows regarding the Airflow orientation on the items I've purchased.

there should be arrows, but you can also recognize the direction by the spec-label position. This is always the back of a fan where the air comes out.

Thanks, you were very helpful. will install as suggested. Might even get a few more, to create a small tornado inside my case.

Is it better to connect them to a fan controller or directly to the psu?
What recommended psu's will make the most of these fans?

It depends on what you want. On a fan controller you can do all manually. On PSU all is controlled via PSU. So its up to you, what you want.

Thanks for your help, I think that the installation of the Kaze Maru units lowered my case temprature by approximetly 10-15 degrees celsius.
