Unsure whats causing very high temps

Recommended Posts

Posted · Original PosterOP

Currently, my CPU is running at 35-40c for an i7 4790K, on a GA-Z97X-Gaming 7 with 8GB ram and a GTX 970. Doing a stress test my temps will curve from 40c to 90c in a blink. As seen below in the image. and will stay at 90+c. I've checked my H100i and reapplied new paste and reseated the Cooler all with no luck being unsure what's causing this. 

 

As you can see in the other photo below I can see 3 TEMPIN sensors for my board. I've worked out that Temin0 is the mobo and TEMPIN1 is the CPU Socket which I would be suspecting to be hot if the CPU is 90c

But TEMPIN2 is the Northbridge which apparently is at 91c and I have no idea why this is so high. I've ran furmark to see if it's just an odd sensor but it doesn't spike if I run a GPU stress test just a CPU one. The northbridge and also the CPU pump are both cool to the touch. 

 

Any ideas on how to fix this issue or even what's causing it? and should i be worried with just a high level Northbridge as it throws all my other CPU readings out of wack.

 

Thank you.

Sounds like the pump on the H100i I is dead.

what type of paste are you running and how restricted is your rad/what fans are cooling it.  I would probably agree that the pump isnt running correctly.

Some say the pump needs to be running at 1800 to 2000 rpm constant, to indicate it's working. Air bubbles in AIO?

Happened to a machine i was working on. Before I removed to clean it, cpu was like in the 40C. Uninstall aio from case cleaned it up and reinstall it. Now at idle, temp would skyrocket to 100C and thermal shutdown. Tried holding the AIO in various positions and even shaking it, and after 3 hours of doing that, it was fix! :D

It was originally the stuff that comes on the H100i but that dried up so i swapped it for some CoolerMaster Hyper Performance (it's all my local PC store hand in a pinch)

Thanks for that comment, But I can actually feel the pump if I put my hand on it so I feel its still working. and the odd things is i have no thermal throttling issues. even with the temps shown here this is why i think its a sensor issue.

Reset bios back to defaults and update bios. Use the stock fan to do a comparison test.

Already done this. This is where i currently am now with now understanding of fixing the problem as i can't adjust northbridge settings.

I can confirm that this is Windows Misreading the temps of my CPU - I have USB booted Linux and done the same test and the max temps, i got was around 60c which is far more what I'm expecting with a base temp of 30c.
