A:AnswerI had the same problem with my motherboard not having enough fan connectors so I bought a Noctua NA-SYC1, 4 Pin PWM Y Splitter Cables for PC Fans, 1 to 2 Converter. This allowed me to attach two fans to one fan connection on my motherboard. The splitter I purchased worked with both 3 and 4 pin connections and came in a 2 pack. You can google fan splitter cables for more info.
A:AnswerPlease note that most Dell prebuilt systems do not use standard ATX components, you will need to check with Dell to confirm compatibility and standards.
A:AnswerI don't know the dimensions of mine off the top of my head, but it says it will fit a 360, this is a blatant lie. It will fit, if you take out the 3.5" drive cage and have no hdd's to put in.
Also, you will not be able to mount it properly even then. The outlet tubes should always be at the bottom of your case. IT won't kill anything, but it's not good for your pump to have them at the top.
