    CPU Fan not recognized by BIOS.


    On an Asus Desktop M32AD. At boot, the F1, CPU fan error screen. I threw a new power supply and a gtx 950 in there. No problem. But I reconnected the hdd and DVD drive backwards in the 3/6GBS ports or whatever and my only hdd was showing up as removable media in the notification area. So I fixed that and now I get a CPU fan error at boot and my BIOS doesn't recognize the cpu fan even though it runs and everything is connected properly. I can just disable the CPU fan monitoring in the BIOS, but that's pretty weak. Any idea of what's going on here? Tons of threads, but nothing of value to me.This is a new computer, all new parts, putting the GPU and Power supply was easy, and there has been no issue with those and I've connected everything properly. I keep checking and trying to find out what the deal is. Really don't feel like sending my computer in. I'd buy another fan if any of you think that would work.

    I recently had a similar problem with a Compaq Desktop running Vista that had a noisy CPU fan. I found out that the computer required the 4-pin [conductor] fan, wouldn't work properly with a 3-pin fan although the fan did operate. Apparently it's all about the signals back to the motherboard about the fan being at the right speed, the CPU is properly cooled, etc.

    How many pins does the CPU fan use? Ideally you want a four pin connector as it will allow the motherboard to monitor the speed of the fan and control its rotation depending on the heat censor.

    This is all stock from the Asus Desktop. I never even disconnected it before it stopped being monitored in the BIOS.

    it could be simply that the cable got loose or the CPU 4-pin is not in the CPU fan header but somehow in a different Fan Header, a quick check won't hurt

    Because you have a stock desktop I recommend checking to make sure your cpu cooler fan is working properly and the connection is secure.

    That warning is designed to inform you when the cpu fan is not working.
    That warning should be taken seriously until you know otherwise.

    Exactly what cpu cooler does you system have?

    First of all, thanks for your reply... But like I said, the fan runs, I have been monitoring the heat and everything is fine. It's just the BIOS not recognizing the fan. But this makes me think the fan just runs at one speed the whole time instead of changing speeds on usage? And I'm a noob, I guess... How would I determine what kind of fan came with this set up?
