Noob Mobo/Fan connector question please help

Hi Guys!

I own a Corsair 550d (quiet case) and an Asus P8Z77-V LK Motherboard.

The case comes stock with two front 120mm intake and one rear 120mm out fan. However, it supports 2 120/140mm on the side and 2 120/140mm on top (not being used YET).

I recently moved to a place that is considerable warmer than before, and am noticing that my fans are having to work a lot harder.

I would like to buy and install a couple more 120/140mm fans in the side of the case (and potentially upgrade to a 140mm in the back exhaust), but my dilemma is that i dont know if my Mobo can support more fans.

I opened the case (for a cleaning) today and looked around the Mobo for more of those (excuse my ignorance) "3-peg fan plug ins" (as i saw that was what my other fans were plugged into) and i could not find any more that looked similar.

Im sure that the mobo supports more than 3 stock fans... but i dont know what im looking for !

I know this is likely tedious for some of you, but any help would be appreciated !

Thanks :)

  1. If that's all the fan headers, then that's it, but you can always get splitters and adapters to run additional fans from the the PSU molex power connectors
  2. You have 3 (4)pin fan connectors. When you put more fans in they come with y-connectors so you can put 2 fans to 1 connector. Or you can wire them up to the case fans and use a molex connector and hook them to your power supply.
  3. 1. Your MoBo manual will have a picture identifying the chassis fan locations

    2. Find out the permissible amperage of your fan headers before doubling up on them. A 2A fan header does not mean ya can connect two 1A fans to it. Ya must account foir inrush current at startup.

    Awesome news thanks for the help

    I have a Corsair 750watt modular PSX ... ill look through the cabling and see what i can find

    And also, thanks for suggesting the Y-connectors, i didnt know that they were an option

    And, thanks for the heads up regarding the amperage of the fans

    I may end up just taking it to a shop and see if i can learn something haha ...
  5. Have any techie friends? Shops are expensive and I've run into a number of techs at shops and like with the Best Buy Geeks squads that know very little

    well a good friend of mine from Vancouver (where i moved from) would know but alas... no one here !

    Anyone have an option regarding 120 vs 140 mm fans? would it be worth it to change my 120 exhaust/intake fans to 140mm instead?
  7. May come down to specs, some 120s move more air than 140s, also will the case fit a 140, may have to mod it to fit/install

    Yup its will fit a 140 or 120 ... corsair gives you the option in most cases, but include drilled holes with rubber washers for either size
  9. Then prob a good option, look for one that moves a lot of air ;)

    Hey so... your third option!

    I may not understand BUT .. is this tool essentially a 5 way power split-er that allows you to control all your 5 fans?
    Like, can i plug this unit into 1 power jack and have it split into 5 fan lines?

    If so im getting one asap ....
