Unable to get past BIOS, CPU now idling at 90C, mobo now chirping

[Frostyz117]

Specs:
ASUS Z270-A PRIME Motherboard
Kraken X42 NZXT Liquid Cooler

i7 7700k 4.2GHz clock

GTX 1080 SU EVGA
Corsair RM1000x PSU
16GB DDR4 TridentZ

My PC restarted during the night and when i went over to turn it back on, i was greeted by the American Megatrends "CPU Over Temperature Error!" warning. Went into my BIOS and my CPU is now idling at 90C while my AIO is still showing as working for my liquid cooler. When i "save and quit" from the BIOS the compute also doesn't restart back into BIOS or windows but just hangs with the fans at a really low speed. During all of this i can hear a 'chirp' from near the CPU. When I turn the computer off that chirp turns into a loud whine for 2 seconds. the red CPU LED on the motherboard is also a solid red now.

 

Here is two pictures of the error and the BIOS showing what is happening and a video of the chirp and whine

probably your Kraken's pump went kaput

[HanZie82]

Or the motherboards voltage driver for the fan port is busted. 
Not able to run the pump at any meaningfull speeds.
Altho i can see it all running in the BIOS screenshot.
Uhm, might be adventagous to open the AIO and see if its blocked or something. Maybe RMA it.

What I think has happened is that the pump on the cooler has failed and it's cooked the CPU.

Then why the still OK pump RPM in the BIOS screenshot?
(Don't mean to contradict but im curious )

It could be a false reading.

so i just remembered i used to be able to hear the liquid in the tubes moving, now i dont. so i guess the kraken is just dead?

Yes that sounds logical, in regards to the CPU leave it over night to cool down then the next day turn it on for a few seconds in the BIOS to see if the temps have come down again (it should).

Well if what @LinusTechTipsFanFromDarlo says is true then yes. That might be a very good conclusion.

Try touching the liquid tubes. If the pump is working it should pump warm water to the radiator, otherwise the heat will stay in sections of the tube near the CPU block

OK Update on it all, subbed in my older cooler and everything now works! however i still dont know if it was the actual cooler that messed up or the specific AIO connector that died since it went to a different port on the motherboard. Ill take it into Microcenter to be test benched later this week. Thanks all for the help!
