Help! CPU fan not working!

[Waldie]

Ok, so it may be nothing, I may just need to tweak a feature somewhere, but I just built my system (E8400, nforce 750i FTW, G.Skill ram, etc, etc).

I just spent all day building this thing, and before you make any advanced troubleshooting suggestions, this is the very first computer I've ever built. So I just booted it up, and all the fans start spinning and their LEDs light up, and it's glorious. But I notice that the CPU fan isn't spinning, so I go into the BIOS, and I check the PC Health, and the CPU temps are already up to 90 celcius, in about three minutes (I had to run upstairs to grab a keyboard).

So, basic question, how do I get my CPU fan running?

plug it in?

[Waldie]

Checked and double-checked before I posted on here, trust me

Do you have another HSF to try it on, or another fan in the same connector?

[geokilla]

Are you sure it's plugged in correctly? Are any of your wires stopping it from spinning?

[Waldie]

The mobo has a dedicated four-pin connection for the CPU fan. I guess I could try moving the connection to another fan spot. All the other ones on the mobo are three pin, although I think I recall it saying that you could plug a four pin fan connector into a three pin spot.

And I tried spinning the fan around manually, with the power off, and it seemed that it caught on the heatsink a little. Not much, but enough that it rubs it a little.

Connect it at some other location. It should not rub.

Ok, connected it to another fan spot. Works now.

Thanks alot! I was nervous, it was my first build. Time to install Windows 7.

Whoa.

Find out why it wasn't working.

You can't plug the CPU fan in an other plug without affecting the CPU fan control management, if you do so you can have some warning, computer shut down, so the power management have to be adjust in that matter. Some control software can have a misleading info too.............. make a hard reset of the board, remove the 24 pins cable and the 4 pins one from the mtb, remove the batt. and short the 2 connector with a screw driver ( I do it with the case of the battt. ) i see funny thing fix doing that, on board who have been on a shelf for a wild.
