System temp about the same, but core temps going up - what's up?

post #1 of 7
Thread Starter 
Over the last several months I've been noticing my fan speeds kicking up more often than they used to. I started tracking the idling core temps and they are now about 6 degrees higher than they used to be for the last... ever. I have already given the case and internals their usual good cleaning, but that doesn't appear to be the problem. The CPU has IC Diamond on it and the cooler is as firmly attached as it ever was. What's this mean? Is my CPU on it's way out? It's been running 24/7 (more or less) since January 2010.

This is not related to the outdoor temps starting to go up, BTW. This wasn't happening at the same time last year or during last summer.

Sounds like your system has Skylake fever. There's no known cure. But, Intel is releasing some possibly effective treatments in the fall.

Or it could be the sensors are getting tired of reporting the same old same old idle temps...have the load temps gone up as well?

When you did your clean, did you replace the IC Diamond TIM? Maybe due for a fresh coat smile.gif

Is there any smokers in the house?
How long has the cooler been installed?
Has it every been removed and the fins washed?

Often after a year or more of use, especially in a dirty / smokey environment the system collects a film on the things. This film lowers the heat transfer ability of cooler and airlfow of fans resulting in higher temps and fans running faster

It's still using the same TIM that was applied when the system was put together back in 2010. I heard stories about TIM drying out but I never knew if that was really possible. I have a motorized air compressor and some fine tipped nozzles; when I clean out the system I get into all the cracks between the fins and blast the dust out of them. No pets or smokers, but it's a dry air heating/cooling type house, so there is a bit of dust.

I'll have to run some stress tests to see if the load temp is also higher than it used to be.

Could easily be TIM is drying out as well as a film on fins. I would suggest taking it out and soaking / washing it in kitchen sink in hot soapy water. You can blow out the water between fins. Be sure it is good and dry before applying new TIM and re-installing. thumb.gif

It's not a hard project and I'm sure it will help your temps.

Thanks for the suggestion.

I could, of course, just consider finally moving up to a Z97 board...exhappysmiley.png
