I am looking to replace all fans in my case, and add some if able to, help me choose and check to see if I can add some Specs are in my sign, and my budget for each fan is $15-20.. Thanks Tom

Edit: I am putting in a h100i inside, so I dont think I can mount 2 more on the top because of the h100i.
So Im looking to replace the case fans..

I've heard really good things about Enermax T.B. Silence: http://www.youtube.com/watch?v=bo-XmL4227Y

I love their shape, they're really quiet and they have nice LEDs.

I was thinking about getting these, would look nice, but not LED, still awesome fans!!

btw my case fans are hydraulic, does that mean that what I get has to be that?
