What makes it worse is that, somehow, you actually claim that blowers are worse. I have no idea how could you ever get to that conclusion. You couldn't reach it testing, because testing will yield completely different results.. so, how?
people are saying what they're saying because dan himself tested the different video card designs and found that the third party coolers perform better in A4-SFX. so yes these conclusions are from testing!
as the previous posters note, third party cooler designs work so well because they input air directly from the outside. NO OTHER CASE DOES THIS. in the old days we needed to build a duct.
I myself used to have the perception that a blower design would work better. I was wrong. the heat-exhaust benefit from using 1 blower fan outputting directly is not as large as the cool-input benefit from using 3 bigger fans. more fans win in A4-SFX.
