Hey Everyone,
So I can not justify upgrading hardware on my computer as it still crushes anything I attempt with it BUT I can justify making the case more fun

I have a dual loop watercooling setup and the fans are wearing out and loud these days so it's time to swap them out. Apparently any 120mm fans will do but I want to get advice from the community on what is BEST for my setup. All the fans it came with are Zalman and Im not sure what cfn or decibel levels they are but Im sure I can improve from whats there now. Ill list what Im looking for:
My aesthetic preference is white bladed fans w/ or w/o LEDs, Quiet, but priority is on better cooling
3x Replacement fans for triple rad on top of hailstorm case
2x replacement fans for double rad mounted outside the back of the case. The bottom one has a metal coil on the outside of it, not sure if that's needed or why...maybe so fingers can't get clipped?
1 x Case fan in middle of Hailstorm between PSU section and Main Section
1 x Hard-drive bay area case fan
Open to suggestion of other areas fan placement could be fun
So basically If someone could point me to a good brand or any specifics that would help alot. I'm not sure what my priority should be on fan speed or air movement when adding fans to a Radiator...
Thanks!!
