Hello all, I'm looking for four blue LED fans in total. Two that are 120mm in size but only 18mm thick to go on top of a Corsair H100i water cooler radiator, and two that are 120mm in size but any width to go in my Rosewill Blackhawk case to optimize airflow. Price is not a total issue, but I'd like to keep it under $15 per fan. However, I am willing to sacrifice a bit more money for performance. I'd like the fans to be very good coolers while being fairly quiet at the same time. Thanks for looking and replying!
