9500 Orientation in an A900? - Overclock.net

wheth4400 · 11-09-07

I was looking for some suggestions on which way my Zalman 9500 should be pulling/pushing air in an A900 case. I have it pulling from the front and psuhing to the exhaust fan on the back of the case, but I am wondering if that 200MM fan up top is interfering with the case's air flow. I am really not getting decent temps at stock I am running in the 40's and OC'd I can get above 60C. SOmething isn't right so I am taking a look at my fan set up here. I have reseated the CPU HSF and reapplied new thermal pastre( using the STG-1 from Zalman). All suggestions are more than welcomed I want to kick this heat issues in the rear

I'd try flipping that monster 200mm fan up top and make it into an intake. Sounds counter-intuitive, perhaps, but consider that the Zalman CNPS9500 lives and dies with airflow. I have a feeling that the 200mm fan on the roof is diverting a good amount of the air that should be going through the fins of the heatsink.

Anyway, this is the fun part of tweaking. Experimenting and testing in real-world conditions beats theory and conjecture 100% of the time. And what's the worst that can happen? You lose some time setting up your fans. But the potential gain is much greater.

Good luck!

A thought I had regarding the Zalman design...
Cut up a pop bottle and trim it out to make a shroud around the HS to channel the air. The flexibility of the bottle should allow it to retain itself.
Do wash it though

just take a 20 OZ bottle and cut the center out and in a half circle to attach it to the HSF?
