CPU suddenly overheating

[ScypeR]

Hi guys,

So I've been sitting on my i7 4930K for quite a while now, and most of the time its been OC'd at 4.2GHz

I woke up a few mornings ago with my computer completely frozen, which happens I guess. After a forced restart it kept overheating over and over again with the exact same settings to voltage and speeds that I've had for about two years now.

 

The motherboard is an asus rampage IV black edition, with ram (DDR3) @2400mhz with the X.M.P profile through the bios settings and then each core in the i7 has been at 42 with voltages on the CPU around 1.200~1.250 can't recall exact values.

I did notice this btw, but I've had the memory at this speed for 2 years with no issue.

Now however I'm at 1.275 volts and 4.0 GHz at almost 50 degrees(44-48) celcius while idle.

I tried lower voltages  but 4 GHz does not work with less than 1.275.

 

So long story short, I need higher voltage, lower clock speed, and I get higher temps.

What am I not understanding?

the All in one water cooler (corsair h100) seems to be working, otherwise I guess it would overheat at idle too?

 

I've tried switching to a new PSU aswell, since I had one ordered I just switched that when I was removing and re-applying new thermal paste.

Dust is also taken care of, it's as clean as a PC can be.

 

Is this a sign of the motherboard failing? bad power distribution or something. I honestly have no idea.

 

Thanks in advance.

Guessing based on the sudden nature of the event i'd blame 100% to the H100i. 1.2 is nowhere near close to electron migration kind of degradation and even if it where the case it doesn't happen in one day all of a sudden but in years gradually. That is discarded.

What could happen to the H100i, the pump died or is underperforming, tubes are bent decreasing the airflow, the radiator is obstructed externally by dirt/animal hair. 

 

Check manualy by hand the temperature of the tubes and the pump. If the pump is hot, it's failing. If the pump and tubes are close to same temperature and both warm but not hot (like 50ºC hot since your CPU seems to be 50ºC at idle dont worry it wont hurt if its 50ºC). 

 

Did you change anything from past days? are you sure you dont have some misterious process eating up your CPU in idle causing the high temps?

 

Best of lucks mate!

considering my cpu needs more voltage and lower clock speed, without failing due to the whea uncorrectable error doesnt that mean its not the cooler?

quite the opposite. If the cpu needed more voltage to begin with, you'd see a WHEA logger you can be sure of that. CPU's don't suddenly overheat out of the blue. It's not how they fail nor how they age.

 

Check the H100 as told. It's dead easy to tell if it's failing. Pump hot = fail 

You coudld try resitting the H100 and replacing TIM too. It's easy enough.

I did completely remove the H100 including the brackets behind the motherboard and change thermal paste etc, so ur probably right, pump is fairly hot

Did you install any new monitoring programs/updates? Check my signature for the possible fix to the issue with Link interference.

My Kraken has a coolant temp sensor, does the H100? If the CPU and coolant is close to the same, I would say coolant is not flowing and cooling for some reason.

replaced it today with a new nepton 240M from cooler master, works like a charm 20 degrees @Idle.
