CPU Fan direction/FreezePro 64

[imported_jasonnovak]

I just upgraded to an X2 3800+ and have a question about airflow. I have two 80mm fans exhausting directly behind the CPU cooler, and two in the front doing intake. I've realized now that the FreezePro is sucking in air, too, so it seems like it's creating some kind of void with both fans right next to each other each blowing in the opposite direction. Reversing the CPU fan seems to not be very efficent, but reversing the rear fans seems like it would really me up flow, too. I also have a 120mm intake fan on the power supply. Is there a better way to set this up?

What case do you have? Link to pix?

If I'm read you right, your case should be

exhaust <---| case <---| intake

with the arrows pointing where the fans are blowing air. The freezer64 pro should be oriented as such that it blows the air in the same direction as the air flow. It should read

exhaust <---| case <---|freezer64 <---| intake

this would mean everything is blowing in the same direction, it's pulling air that's already moving in the same direction anyways. In fact, this is how I have my computer set up with a freezer64 pro though the intake fan is at the bottom of the case while the exhaust is right behind the cpu.

It have a chieftec matrix/ie dragon case. I never throught to rotate it ... I was thinking of one of those ducted systems, but I guess that really doesn't apply

I'd duct one of the rear 80mm holes to the CPU fan (may need another 80mm fan at the end of the duct blowing in depending on the strength of the CPU fan) or duct to the side door and block one of the rear holes, and put an 80 to 120 adapter on the outside of the other 80mm hole for a 120mm exhaust fan. If there is room above the PSU, I'd flip the PSU so the 120mm intake fan on the PSU is toward the top of the case - that way there won't be any fan starving going on.
