Mysterious CPU Fan error

Posted 05 December 2013 - 12:26 PM

Hello guys,

When I turn my computer on, the start process is paused by the annoying screen bellow

When I access the Setup, there is no mention of this error, so I can do nothing but to quit the UI powerlessly. Hopefully, the start process continues and I have access to my OS.

I can see the fan spinning and ASUS' software tells me that everything is fine (the fan is just slightly slower than usual)

There is no information about this error in my user guide.

My heatsink is a Thermalright HR-02 Macho.

Any clue about what's happening before I take one hour to unmount the monster with no proper tools ?

Many thanks !

If you have fans with similar connections, I would try hooking up one of those & see if the error goes away. Meaning, multi-wire fans will actually feed i/o back to the bios for just this sort of error reporting. It's possible that the fan is failing, it's possible that the communication is being lost or interrupted. On a cpu, I wouldn't risk it. The cost of a replacement cpu fan vs the cost of a replacement cpu is an easy no-brainer.

Again, just in my opinion this is how I would proceed.

Is the cable loose? Did you plug in the fan to the cpu fan connector? have you tried lowering the rpm in the bios? Have you tried lowering the fan warning level in the bios? Are you doing anything silly like OC?

WAW, that was fast... Thank you all.

The fan seems to be plugged correctly

I didn't touch anything in the BIOS except the boot order. Everything is set to AUTO (there is an auto OC though, but I guess it's gentle). I have built this PC 6 month ago. It has always worked fine until a week ago.

I noticed that the fan speed floor is set to 1000rpm (the CPU fan is spinning at 700+rpm at the moment). I wonder if this error could be a simple warning, but I don't understand why it would be thrown only now.

no2pencil, I don't have any other fans than the ones included in the case but I can buy one for the test, it's not that expensive.

I'm not worried about the temperature right now. The heatsink is huge and could almost be used as a passive cooler. The temperature is also surprisingly low at the moment (5 more degrees over the room's temperature)

Hello people,

Since the last time I wrote I've done some experiences and it seems like both the fan and the motherboard work fine.

I am wondering : is it possible that, because the weather is colder than this summer, the low temperature of my CPU doesn't require a hi fan speed and, as a result, the fan spins naturally slower than before, and below the speed floor set in the BIOS ?

How does that sound to you ? The temperature of the CPU is 30C at the moment after 1 hour of gentle use.

The only thing that I've noticed different between seasons is that blown capacitors will cause failures in the Summer because of Air Conditioning or in the Winter because of extra heaters.

My understanding is that the extra electricity on the line isn't filtered because of the blown capacitors.
