i was on the net looking for a fan for my case...


but then i saw something on the Cooler masters home page.

they said that the lower the, RPM is the cooler is it! ?!

they made an example with a 200mm fan and a 120mm...

the 200mm had 700 RPM

and the 120mm had 600-2000 RPM

and they say that the 200mm is much..MUCH cooler then the 120mm fan

is it true ? :heink:  :o 
and how/why :( 

thanks :)

one fan is 200mm and one is 120mm, the bigger the fan the more air it will move.

a 200mm fan at 400rpm can move 2.5x as much air as a 120mm fan at 1200rpm*

Larger fan blades (200mm vs. 120mm) move more air, even at the lower RPMs, thus the "cooler" comparison.

Now that being said, you can only install the size of fan (unless you custom cut your case) that your case supports. So, if your case only supports installation of 120mm fans, you can't install a 200mm fan instead.

What make/model of case do you have and how many fans do you currently have installed in it?

cases like the HAF 912 give you the option of 1x 200mm or 2x 120mm up front and up top

Understood and agreed. Still need to know what make/model of case the OP is using. Good point, nonetheless.

Nice choice. Also keep in mind that since the larger fans typically turn slower, they tend to run quieter, while moving more air. This is a good thing. Good luck!

Airflow is measured in cfm (cubic feet per minute), thus, a larger fan which contacts more air can move more air thru a larger opening at a slower rate.
