I have an Asus RIVE and a 3930K.
I put my computer to sleep and came back hours later to turn it back on; it started acting up, going into a sort of kernel panic where it would try to boot but nothing would come on the screen, it would power off and then power on again automatically, over and over. So I shut it down, turned off the PSU and unplugged it, waited a minute or so, plugged it back in and powered on and it booted to a CPU fan error.
Inspecting the fans I found that the main fan on the cooler (I have a Noctua D14) was stopped. I opened the case and played with the fans and found that the stopped fan worked fine on other fan headers. I tried a 3-pin fan on the CPU fan header and it worked fine; I tried another 4-pin on the CPU fan header and it also would not start.
So I turned off fan control; fans ran fine. I fiddled with the BIOS some more and set the CPU fan profile to manual and tweaked it a little. I restarted several times and it seemed to work fine, so I put everything back together and sealed up the case and restarted and... CPU fan error. So I went into the BIOS again and disabled errors for the CPU fan.
Booting into Windows I played with Realtemp, HWInfo, Open Hardware Monitor, Speedfan and the Asus PC Diagnostics tool and found that at idle the CPU opt fan runs at about 200 RPM, and maxes out at 300. The CPU fan idles at * 0 * and also maxes out at 300 under load. I set the CPU fan profile to turbo in the BIOS, no change. I tested my hardware with the Asus utility and everything seems fine. Realtemp reports normal temps at idle and under load, about 30-35 idle and maybe 45-50 during a stress test. Ambient temp is 19. Not great temps, but not horrible either.
What am I missing? Is my mobo or CPU failing or partially failing? It seems like they are not getting enough power to those two fan headers. Could it be a failing CPU or a damaged VRM?
