They are all pretty much the same, give or take a decibel or cfm.
Faster = better = louder.
Panflo, sunon, delta, pabst, evercool, thermaltake and enermax all make good fans, its just a matter of
chooseing the speed noise level and features.
For example, pabst and panflo specialise in making balanced quiet fans, so they may be slightly better. Enermax and Thermaltake make adjustable fans, a good invention that lets you control the speed & noise.
Possibly the best looking fan is the evercool aluminium fan. All aluminium frame with silver colour blades. VERY spiffy.
