CM690 with the Hard disk cage turned in a wrong way,

Recommended Posts

Hello , in my opinion the orientation of the hard disk drive cage of the CM690, can restrict the airflow into the case , look at this AirFlow Cases Laboratory Test , to check , how the orientation of the walls of the Hard disk cage parallel to the side panels of the case give the best airflow in the Cooler Master Stackler , Akasa Mirage and Antec P180 , in comparison with the other cases in which the hard drive rack is turned in a wrong way ,restricting the air flow from the front intake fan,

This is part of a review about the CM690 ,I got in magazine CUSTOMPC ( issue 052/january 2008 ) here in London ............."However ,while the hard disk have a dedicated 120mm fan, little air flow will access the main chamber ,as the hard disk cage is mounted perpendicularly to the case " ...........................

this is the problem...44351.jpg

QUOTE FROM............ "iron_gr"

Bought this case. It's nice, a little more noisy, I expected it more silent.

It has a production error! The ground cable of the IEEE 1394 above the I/O panel is not grounded! It is with the screw that holds the i/o panel in place. I took it from there and grounded myself straight on case.

If you can pass it to the guys that put it together, would be nice.

:D Hi ,I got this in a australian website....... hppt://forums.whirlpool.net.au ...... ,the owner of this CM690 rotated 90 degrees the Hard drive Rack to face front to back instead to leftside-rightside to improve AirFlow inside the case ,this are his words :

Yes this a nice case for the money

Bought one yesterday without power supply

Had to modify the hard drive bay to increase airflow (rotated 90deg)

Very quiet running 7x120 fans (inc. cpu)
