6700K suddenly crazy hot under NZXT Kraken X62

[oscar7601]

Hi everyone,

 

A friend of mine is facing an issue with his computer. It's been running fine for about two years with his Core i7 6700K cooled by an NZXT Kraken X62.

But all of a sudden, his CPU temps has started skyrocketting.

I'm talking about 127°C on the CPU at idle, with no BSOD.

The fans are yelling at 100% speed, but the temps don't go down.

 

What would you suggest he does to diagnosis the root cause of this issue?

I told him it might be the pump of his X62 which might be dead so I told him to swap it with a random spare air cooler he has lying around, just placing it on top of his CPU without even mounting it just so as to see if the temps are more realistic.

 

However, I am very surprized that he did not get any BSOD with such temps. How come?!

 

See below screenshots both in the BIOS and in the OS.

That's what I suggested to him.

I'm waiting until he tries with the air cooler. But he told me that one of the two tubes coming out of the block is hot and the other one is colder.

Is it possible that the pump would run very weak?

if that ever happens its the AIO, if its the pump or else it needs to be replaced.

Yes of course  

What I was asking was whether someone had ever heard of a pump running but slowly instead of dead simply dying?

no, its more likely a blockage.

are the tubes on the radiator on top or on the bottom, maybe missing some liquid and if the tubes are on top youre pumping air sometimes

 

also i dont see CPU temperature in the screenshot, show per core temps

Most likely it is sensor's fault. If CPU was really that hot, it would have shut down to prevent damage.

Yeah it really triggered my curiosity when he told me he hadn't gotten any BSOD with such temps...

Yet I believe some bios let the user deactivate BSOD in such conditions. Yet I doubt my friend would've done that.

I know someone who plugged the pump to the motherboard and those pins died slowly, cutting off electricity sometimes and causing a "pump failiure", so it just worked sometimes. After swapping the AIO twice he then notice that the issue was the motherboard, so yeah, pump could "fail" sometimes, and sometimes not

Good idea i'll tell him to plug his pump into another connector.

Edit : He already tried that and it made no difference.

I also vote dead temperature sensor....I suppose if he installs the CAM software he can check what the fluid temperature is to see whether the cooler is working or not. I have no no idea what to do about dead CPU temp sensors though?

[oscar7601]

So he swapped his AIO with an air cooler and the temps have gone down to more normal ones

So it turns out it's the Kraken X62 which is to be RMAd.

Thanks for your help and suggestions.

I'm glad it wasn't the CPU's temp sensor!
