Twin Frozr 3 vs Twin Frozr 4?

[Rezoe]

are there any benchmarks running these 2 coolers against each other?

Before this is added let me say the Twin Frozr 4 comes with dust removal technology, how this works is the fans spin the other way on start causing air in the cooler to blow out of the card removing any potential dust build up then stops and spins back the normal way blowing air in.

That being said, is that the only thing different between the two?
please post if you have any incite.

Both should work very well, and I don't see any more features except from the dust removal and they tweaking it a little bit.

I can't imagine a very significant performance change. There is nothing really all that different that shows us that 4 would be better. Longevity of the cooler possibly yes, but other than that I don't see much of anything.
