I have a CM690 case and have 4 LED on/off Coolermaster fans

http://www.coolermaster.com/product.php?product_id=2579

and 2 black fans that came with the case,

i am looking to upgrade to AC Ryan Blackfire4's

http://www.specialtech.co.uk/spshop/customer/product.php?productid=6071

because of the higher CFM, so i thought that i would just replace my LED on/off Coolermaster fans. but would the increased CFM interfere with the two stock coolermaster fans that have a lower CFM?

Thanks in advance, rob

There are two chains of thought. Higher airflow into the case or higher airflow out of the case... both have plus and minus points (positive & negative pressure) but to be honest as long as the case maintains a decent and unobstructed airflow through the case it waont make a huge difference.

Brilliant cheers, well i was thinking...

i might get these xigmatek ones

because of the higher air flow compared to my coolermaster, although it is a littler lower compared to the AC ryan fans and plus they are more quiet! bonus!

I think i might just replace them all...

Thanks for the response though,

Rob
