Hello I have been using a new build for the last 4-5 months and just recently came home to find the fans were running high and a lot louder than normal. I was on the sign on page for Windows 10 and the system was running so slow I decided to do a hard reset. Now the system boots to a black screen that tells me there is a fan error and the the CPU is overheating. It then tells me to change fan settings in BIOS, but it's pretty vague and I'm not sure how to fix something like that. Does anyone know how I can fix this or even what might have caused it?

1. open the case and see if the fan is spinning.
2. download hardware monitor http://www.cpuid.com/softwares/hwmonitor.html and check your temps. report them here. classify them as idle temps and load temps, also tell us your room temp
3. if the temp is 40C idle, that's about the highest a chip goes in idle, and load you don't want to pass 80C for intel, 72C for AMD.
4. If the fan isn't spinning, get a new cooler. if the temps are high and the fan is spinning, reseat the cooler and apply new thermal paste (get AS5 or MX-4).

Unfortunately I can't even get the machine to boot. Immediately after powering on the CPU fans speed up to the max and the system shuts itself off. I'm guessing as a safety precaution. It's almost as if the temperature sensor is misreading the CPU temps and causing the machine to crash. Also when I was in BIOS it was reading the CPU at 89 degrees C right after booting. I don't see how that's possible.
My room temperature is around 60 or 70 degrees most of the time and I keep the A/C running most of the time as well. I've been using the same system in this room for two years now, and a few months with the new hardware I installed. No problems until yesterday.
I'm using the Corsair H100i v2 cooler and I just cleaned and reapplied the AS5. Still the fans are spinning up on startup. I only get a little time to play around in BIOS before the system shuts itself down.
This is the message I'm getting on the startup screen. It's on the BB code.

Not to tell you that you did something wrong, but in some cases people forget there's a thing called thermal paste....
So did you clean off the old paste and put new on? Is your pump plugged in? And as I said feel if there is hot water in one tube off the rad, and cold in the other.

I ended up changing the motherboard out for a slightly older model with a different processor and hooked up a different cooler (still of the corsair H100 series but just an older model) and I encountered the same issue. I reseated and reapplied thermal paste again and noticed that the pegs I was mounting the cooler on were sitting high and the thermal paste was still in a pea shape on the cpu and it wasn't seating correctly. I then swapped out the pegs around the CPU and replaced the cooler and the temps seem to be holding stable. I have been using the PC for about a month now and no issues. I am going to be selling that PC now or retire it to the living room. I still have the ASUS ROG motherboard that is pretty epic so I will have to sell it or find a use for it. Thank you for the responses. I'm still not sure what caused the problem to begin with but everything is working at least now.
