This may seem like an odd question, but I'm trying to figure this one out. I'm currently looking to purchase a "VGA Silencer" from Artic Cooling for my ATI 9800Pro. The version for that card is "Version 1", now at "revision two". But you can still find the revision 1 card for sale from most distributors. Besides the fact that the "rev1" cooler has a blue fan and "rev 2" is a nice black, I also noticed that the long fan blades curve INTO the spin on the "rev 1" and AWAY from the spin on "rev 2". "Revision 1": "Revision 2": (Notice the direction of the fan blades. The fan spins clockwise on both.) You would *think* that the rev 1 fan would be better, but the only difference between the two cards given on ATI's website is that "rev 2" is now compatible with their "All In Wonder" cards. No explaination as to why they changed the direction of the fan blades. So, can anyone explain this to me? Is the "rev 2" fan actually better than the "rev 1"? Too weird.
