CPU at 100° with Kraken X52

[AnalogCanavity]

I built my PC in 2017, and my Kraken X52 has been working fine all these years. I had just reapplied the thermal paste about a month ago, but it still worked fine after that so that’s probably not the problem. But this morning I turned my PC and got this error message: “CPU Fan speed error detected” (picture below), the fans on my Kraken X52 were still running so I assumed it was a software error. Regardless, I went into BIOS and saw that my CPU temps were increasing 1°C about every second, and once it got to 75°C I just shut my PC off. I pulled the power plug, waited a minute for all the motherboard lights to turn off, once they did, I plugged it back in, turned it on, but got the same error message and high temps (70°C+ when idle). Next I unplugged my PC and took out the CMOS battery for 30 secs, still the same problem, and I got a “CPU Overheating Error” (looked like this). Then I went in my PC again and made sure all the Kraken X52 SATA, USB, and Fan connectors were plugged in correctly (and they were), still the same problem. I also tried using this guide I found to no avail. Finally I just logged on to my PC, thinking that this could be a BIOS issue, looked at NZXT CAM and saw 95°C CPU Temps, I immediately shut down my PC to avoid permanent damage to my CPU. 
 

So far there are only 3 problems/solutions that I can think of:

 1. My Kraken X52 Pump has failed, and I need to get a new one.

 2. The CPU temperature sensor has broke, and I need to get a new CPU (unless its a software problem)

 3. ? ? Something totally different ? ?

Yeah I'd say it's the pump. 

Do you happen to have a PSU jumper so you can run the AIO on it's own without the system? You can actually feel if the pump is working when the tubes are slightly vibrating when you touch them.

The most likely cause for this issue is the pump or the header it is plugged into.

 

So the first thing I would do, is to plug the pump into a different fan header, assuming it actually plugs into a fan header at all. I never touched a X52 before

You can also check whether the pump is working or not by either feeling the pump cover, which should vibrate slightly or listen to it. Simply put your ear next to it and you should hear a noticeable humming noise. (Make sure you don't mistake it for the fans' noise)

 

I assume you don't have an air cooler, since your 6700K doesn't come with one.

But in case you have one, replace your AIO with a different cooler and see if that changes anything.

 

I don't think the temp sensor failed. Usually they then either read some ridiculous numbers like a billion °C or simply read 0°C.

These temps look way to realistic for it to have failed.

 

Btw.: Don't worry about your CPU. Your CPU will throttle itself down to prevent it from overheating or will shut down before any damage can occur.

Keep in mind Intel specifies a TjMax for the 6700K at 100°C.

(For some reason they got rid of TjMax on Intel Ark and replaced it with Tcase which is specified at 64°C. Doesn't make any sense tho. Weird...)

Ok, I will listen for the pump. Also the pump plugs into a SATA power port, and my HDD is using the same cable from the PSU, and my HDD is showing up in the BIOS so I don’t think it’s that. Thanks though!

Sounds like the pump to me, in the NZXT software it should show what the pump is running at. Or if you feel the tubing you should be able to feel the flow. If you need to test it another way you can test it with a cheap air cooler and if it all works well you can send the AIO in for RMA and use the air cooler until you get the replacement or you can just buy a new one, whichever you prefer.

I agree, sounds like a dead pump.

Which is exactly why I'll never have an AIO.

Just tried using a PSU Jumper, unplugged everything but the SATA connected to the pump. I heard and felt the pump/water flow, so maybe the pump is not pumping fast enough? or this is a software error (that happened overnight).

 

Thanks
