Panaflos are incredible fans, the only thing is if you are looking for even quieter fans there is the Acoustifan but that is like 20 dollars whereas the Panaflos are only around 6-7$. I have 3 in my case right now (2rear, 1 CPU) and i am going to get more.
While on this, with my last order my Panaflos came with the 2 pin connector, On one i ripped the cables out of it, then ripped it out of my 3 pin connector on the old fan and jammed them in the 3 pin connector, it worked but it looks like sh!t. On the other fan i just clipped the little notches at the top of the 2 pin connector, and put it on 2 pins and left 1 bare, is there a better way of doing this.
