Blower coolers can be good or bad, it really depends on the quality of the components involved. I hate to bring Nvidia into it, but there FE blower coolers are actually pretty decent, AMD's reference blower coolers have not been nearly as good the past several generations in my experience. We shall see how well the new cooler and GPU from AMD fares in HH's review in a few more hours. I do like a blower cooler for the bottom GPU in a Crossfire/SLI setup to exhaust as much of the bottom GPU's heat outside the case instead of it rising up into the top GPU. With a blower cooler on the bottom and an AIB cooler on the top I've done well with the last few dual GPU systems I've dealt with.
