Case fan issues

[sullione]

I have a question and I already tried searching for an answer so please don't slam me if I overlooked it while searching through numerous posts. Anyway, I noticed that the fans (120mm) in my Armor case doesn't start when I first start my computer. They won't turn on either until I put the comp. to standby and then "wake" it up. The cpu will start to heat up and engage its own fan at max rpms but the case fans wont come on until I do the procedure above. Does anyone else have this issue? Could my problem be because I have them connected to motherboard headers (A8N32-SLi Deluxe) instead of just running all the time? Thanks in advance.

Yup, the BIOS settings are what's causing this.

Ok, I've changed the settings in the BIOS but still no change. Also, when the fans are on the spin at no more than 650 rpm and the temp software sounds an alarm. Should they spin faster than this or is this the normal speed. I haven't come across any specs for these fans other than their size.

Yes.
Or the Bios setting....or both.

Buy some adaptors and run them off you PSU.

Hey Sulli,
I have the same mobo and I do not have that issue. I DO HOWEVER have 3 speed 120cm fans and at low setting they spin about 750 rpm, medium is bout 1100 1200 rpm, and 3rd speed is round 1500 rpm. Like the other dudes said .....check bios and make sure that it is not being "controlled". YOu did not mention if you have 3 speed fans. If you DO, make sure they are set to hi speed.
Did you build this yourself?

EDIT: Z dude is right....your fans SHOULD run off your PSU, that way when you power up, your fans will also.

Hope this helps bro

Thanks for the replies guys. I'll tinker with it tomorrow. I'm sure it has to do with the way I hooked them up. I'll let you guys know what I find. And yes I built it a couple of weeks ago.

The thermaltake fans in the armor have two connections, one for power and one for fan monitoring.

If you look at the 3 pin motherboard header you'll see that it only has a yellow wire not the red and black ones for power.

How do you have these hooked up exactly?

I have both connectors hooked up on the 120mm fans. I have the molex connectors hooked up to connectors from the power supply marked "fan only". The three pin connectors are hooked up to three pin connectors on the motherboard. The rear fan is hooked up to "Chassis 1" and the front fan is hooked up to the NB connector. The power supply is hooked up to the "Power" connector. One more thing, should I have the EZ Plug hooked up? The way I read in the manual, it says to hook it up IF the video card(s) do not have their own power connector...which mine does so I didn't connect it. Is this correct?
