Yes I Have outstanding airflow. See my build:
Four 120mm Fans blow onto VGAs
Six 120mm fans stacked above and below radiator blow out the top of the case.
2X 40mm fan blow directly into upper VGA
PSU Heat is shielded with custom box and blows out of the case with an additional fan on the exterior of the case behind CPU.
Massive front fan intake blows half through to CPU and half through HDs and VGAs.
Rear 120mm fan exhaust.
A 40mm and a 60mm fan blows heat away from the upper VGA through NB heat sink.
System is "Dust Off"ed regularly.
You may notice my south bridge mod I added to the stock heat sinks of the MB. I added a metal shield out of pop can material that slid around the right and top sides of that heat sink in an attempt to minimize the heat entering the top VGA and it made no difference to the temps, so I removed it.
I have done numerous stress tests with different programs. No changes to my problem of freezes. The system is stable, even under aggressive OCing. The problem is completely random. Grrrr...
EDIT: I wanted to add to that last bit. I have run stock speeds, under clocked speeds, tried many different voltages and still maintain very low MB, NB, SB, temps. The VGA fan problem seems to have no particular issue with running games, video rendering, or just plain old 2D browsing and such. It is totally randumb!
Anyone have more thoughts?Edited by Paraleyes - 4/1/11 at 8:24am
