That is the fan I currently have (Ultra Kaze 3000)... It is the one making the clicking noise from 2000 - 2500 rpm. So the Panaflow is better than the Kaze 3000?
Oh jeez I shoulda looked that up Not sure, maybe try something new if your adventurous? Really its just a $10-$20 fan so you might as well go with a Panaflo or San ace. Thats just my opinion though; I do love this ULTRA KAZE though.
If I wasn't going to buy another Kaze or the Silverstone then I would go with the high-speed Yate Loon. It moves a lot of air and you can order a couple of them for spares at $6.99 a piece
