what is the appeal of blower-style cooling?, i always heard about it being worse for cooling
They're really only worse in the sense that they can be louder. In a datacenter/mining rig/etc where you don't care about noise at all, they're pretty much the best solution to cooling a large amount of cards as they blow air out near the outputs instead back into the rack.
Thanks – and what is the quieter solution vs. blowers? Liquid?
The liquid system really just helps move the heat to a new place in your rig. To get rid of it, in general the bigger the fan the more air it can displace at a lower speed, which in turn means less noise.
A good liquid system which moves the heat to a radiator at the top/front/back (depending on where your have clearance) of your case and big fan or fans to push it out would probably work best
