Installing new case fans (help please)

Hey guys. I'm not that smart with computers but I'm quite capable of doing simple tasks if I have someone to confirm my decisions.

At the moment I have a ASrock z77 extreme 4 MOBO and a thermaltake case http://www.thermaltake.com/Chassis/Mid_Tower_/V_Series/C_00001616/V4_Black_Edition/design.htm with only 1 case fan in it which is in the front.

I'm looking to put 2 more case fans in 1 for exhaust and 1 for intake..

I'm looking at purchasing 2 of these. http://www.pccasegear.com/index.php?main_page=product_info&cPath=9_510&products_id=26657 (also if anyone has any feedback on these fans would be great!)

I know they run off pmw 4 pin and my MOBO seems to only have 1 4 pin which has the cpu fan plugged into it. The other 2 pins next to it are 3 pined (called pwr fan 1 and cpu fan 2)

so my question is what do I need to do to work around this if I'm looking to put 2 of those fans in. if you choose to answer this please do not assume I know certain things about splitters ect. would apprecitate some deatail!

Thanks heaps in advance.

  1. The easiest method to control your fans (without motherboard 4-pin fan headers) is to get a bay mounted fan controller. The cougars are average. Don't mount them horizontally or they will tend to make noise. I would recommend Noctua fans instead.

  2. you can still connect 4pin fans to your motherboard you will just not have the option to control them within the bios
    because the blue wire is for control

    the blue wire
    but they will still work fine
  3. But note that they will ruin at 100%, so purchase fans with lower RPM's to avoid noise. You can also use low noise fan adapters to slow a fans RPM.
  4. fans are designed to run at 12V they will not ruin , however they may be loud.
    I would suggest buy some fans with 3pin cables pccasegear have a good selection
    from quiet to performance to high CFM

    If I plug them into the MOBO can I just use a program to control the speeds?

    possibly with speedfan or another similar program you or you could get a fan controller that supports 4pin fans as terry4536 suggested or
    just buy some 3pin fans , lots of choices out there , led or non led , silent etc pccasegear has a good range
