stufz Posted September 25, 2011 Share Posted September 25, 2011 Hi - I finished the build the other night, and was able to fire up the 400R. I'm using the CM N520 heatsink/fan cooler, which uses 3 pin connectors and will not fit the 4 pin mobo connectors - ASUS P7P55D-E LX - so have connected the cooler's single lead to the power fan connector. Today at first startup, I realized that the front fans were not spinning - no LED at first, so I thought I had hit the LED switch. Nope. So the 2 front fans are run together into a female molex - which I then connected using a molex cable with 3pin male/female connectors and plugged it into a Chassis fan connector that had been powering 1 of my addon Scythe fans. Still no spinup on the front fans. I don't know what to do now, I've never had a fan spinup problem, and I've managed to get thru about 2 dozen pc builds over the last few years. I'm not sure if this is a Corsair parts fix or .... ? thanks for the read .. and here's a pic of this build http://theblackduck.net/pix/whole_case_w_cm520a.jpg Link to comment Share on other sites More sharing options...
Toasted Posted September 26, 2011 Share Posted September 26, 2011 hi, Can you try plug the fan in a different system? If it still does not spin submit an RMA. Link to comment Share on other sites More sharing options...
stufz Posted September 26, 2011 Author Share Posted September 26, 2011 ouch .. um i'll take a look. RMA the whole case ? or can I get by with just the fans ? I'll look. Thanks Toasted ;): Link to comment Share on other sites More sharing options...
Toasted Posted September 26, 2011 Share Posted September 26, 2011 if the fan is on the parts list then use that. If not use the 400R and tell them that the front fans are faulty. and that you don't need to send a new case over, just fans. Or they might just send a new case over.

stufz Posted September 29, 2011 Author Share Posted September 29, 2011 Good, I did that, I just got a reply for contact/address info, they'll see about what to send. Is there a parts list somewhere ? I couldn't find anything.Thanks, Toasted :) Link to comment Share on other sites More sharing options...
Corsair Employee RAM GUY Posted September 30, 2011 Corsair Employee Share Posted September 30, 2011 The fans that are not working where do you have them plugged in? Have you tried another plug on the MB? Link to comment Share on other sites More sharing options...
bomb3rboy Posted October 13, 2011 Share Posted October 13, 2011 The front fans on my case doesn't work either. When u say where are they plugged in, is there suppose to be a wire that goes onto the motherboard? I'm asking this because I saw the wires from the 2 front fans go up towards the power button.

I'm right there with you man. just built my computer with this case today and had the same question. I saw how the cable went back up to where the power button is, i figured that maybe the power ran through the switch and then to the fans... but they're not lit up or spooling up. so how are we suppose to attach these front fans to the mobo?

Toasted Posted October 13, 2011 Share Posted October 13, 2011 @bomb3rboy & bones311 There may be a molex connector coming out from the front panel. Because the wires going up to the front panel is for the fan controller. Find all the wires that are from the front panel and see if you can find the molex connector.

Nahaz Posted October 13, 2011 Share Posted October 13, 2011 When I looked at my front fans for the first time I couldn't see the connector either. Look closely and you should see 2 thin wires connected to a molex cable. Plug that into your PSU and your fans will work. There is no 3 or 4 pin connector as the fans are all wired up to a harness for the molex power. Mine was tucked inside a 5 1/4 inch bay. Link to comment Share on other sites More sharing options...
bones311 Posted October 13, 2011 Share Posted October 13, 2011 @toasted and Nahaz. thanks guys... i found the connector. basically like Nahaz said. the two front fans run into a wire that bridges them... and that wire runs into a 4 pin peripheral plug. pluged it into my psu and im good to go. I dunno how I missed it when I was plugging everything in. hopefully bomb3rboy gets his attached. Link to comment Share on other sites More sharing options...
bomb3rboy Posted October 15, 2011 Share Posted October 15, 2011 K, I got it working, found the connector under my psu's wires lol Thanks for the help! Link to comment Share on other sites More sharing options...
stufz Posted October 15, 2011 Author Share Posted October 15, 2011 wow, cool. My molex connector didnt work, so I was able to run the fans' own 3 pin connectors to the mobo - long enough. And I just got my replacement front panel controller !! woohoo ! lil bit afraid to try it but I will, I want to see those front fans led's light up WHITE !

wyhtmgm Posted October 18, 2011 Share Posted October 18, 2011 I had no trouble finding the Molex connector, but it's female, and so are the ones on my power supply cable. When I first saw the female connector I assumed it was there for me to plug another fan into. But, I can't find a male connector. So, do the front panel fans really get their power from a female connector, and why? What am I missing? Link to comment Share on other sites More sharing options...

wyhtmgm Posted October 18, 2011 Share Posted October 18, 2011 the fan connector has a male side and female, i made the same mistake at first but then i looked at the reverse side. you could actually daisy chain off the fan connector When I read that I was sure you must have a different connector than I do, but sure enough, upon further inspection, the pins are there. I was looking for something with protruding pins, which gives you some idea of how long it's been since I assembled a system. Just for laughs here's another "Man I sure am rusty" anecdote. While waiting for your reply, I found a male-molex-to-4-pin-female adaptor, which seemed to be exactly what I needed. I tried it, but it didn't work, and the latch didn't fit quite right. Eventually I realized I was trying to power a fan with a floppy drive power connector. I disconnected that, but forgot to reconnect the rear power fan, so I then proceeded to install Windows 8 (preview) with only the power supply fan and CPU fan running. Fortunately I was using a 95W CPU and an SSD, so the only thing the power supply fan really had to cool was the power supply. Link to comment Share on other sites More sharing options...
ejc5105 Posted October 22, 2011 Share Posted October 22, 2011 I'm having the same problem and I am still not quite understanding this (My first computer build). Do I need a separate cable that was not included with my case? Someone had the same problem in another thread and posted these pictures http://forum.corsair.com/v3/showthread.php?t=99464&highlight=fans (Post #5). This is the 500R, but the I have the same cables as are shown in the pictures. Link to comment Share on other sites More sharing options...
Nahaz Posted October 23, 2011 Share Posted October 23, 2011 As explained before, your front fans are all wired up and are powered from a normal 12 volt molex plug. You should find in your case a black molex plug that is then used to power the front fans. Just trace the fan wires after they plug into the splitter and you should be able to find it. Use a 12 volt male molex from your PSU and connect it to the black molex that has both fans connected. See below for example. http://i19.photobucket.com/albums/b170/Zahan/molex.jpg Link to comment Share on other sites More sharing options...
