marcos9999 Posted November 2, 2013 Share Posted November 2, 2013 Just assembled my first computer. After connecting all cables...the beast roared to life when I flipped the switch. I noticed however that my case an Antec 1200 with 3 fans build in only had access on the board (Gigabyte Z77MX-D3H) to two of them since one had to go to the processor's fan, there are also 4 bays and 3 more fans there (empty now) so my first question is, how do I connect these other fans if I need? So far it's doing really well with just 3 fans I assume. The other issue is that one of the usb ports in the front didn't work...don't know exactly why, the other two did fine.

abarbarian Posted November 2, 2013 Share Posted November 2, 2013 http://www.quietpc.com/instructions/gigabyte/ga-z77mx-d3h.pdf If you check out the above you will see that the mobo has THREE fan connections. Fan 1, Fan 2 and CPU Fan. http://www.shinyhardware.co.uk/prods/showprod.asp?pid=928 http://www.watercoolinguk.co.uk/p/3-Pin-Fan-Power-Splitter-Cable-1-x-Female-2-x-Male_29797.html The two above links show two different types of adapter for adding extra fan power points.

raymac46 Posted November 3, 2013 Share Posted November 3, 2013 The power supply usually gives you a Molex connection and you can get adapters for these that will connect fans. Quote Link to comment Share on other sites More sharing options...

amenditman Posted November 3, 2013 Share Posted November 3, 2013 I always try to use the splitter type of adapter so that if the fans are controllable through BIOS all the fans are able to be controlled. If you use the molex type to connect to the power supply, you will have no control. The fans will run 100% all the time. Unless you are doing intense video/gaming or extreme cpu usage those three fans should work fine. That case has two USB 2.0 ports (black) and one USB 3.0 port (blue). Which port is not working? If it is the blue one, you probably forgot to connect the cable to the motherboard. There is a blue socket near the RAM slots, it has 20 pins and a slot in the middle of one side. 1 Quote Link to comment Share on other sites More sharing options...
raymac46 Posted November 5, 2013 Share Posted November 5, 2013 (edited) Well my Cooler Master case only came with one 120 mm cooling fan at the bottom front so today I bought and installed another one in the top rear of the case. While I was at the computer store I picked up a proper fan extension cable that allowed me to plug the front fan into the header on the motherboard. Before the cable wasn't long enough so I had to use a Molex connector from the power supply. This allowed me to unplug the clunky Molex cable from the power supply (it's modular.) My cable management got a lot cleaner (or less bulky I suppose.) There was a convenient mobo fan header for the back fan right near the CPU fan header so that was where I plugged in the second fan. I figure this should give me plenty of cooling given that I don't have a graphics card in this case.
