Outrageous i5-2500k temps?

[myrmidon]

I'm using a Arctic Cooling Freezer Pro 7 Rev.2 along with my 2500k.

According to ASRock's mobo utility, it's idling between 41-44C.

There's no way this is right. Could it be that I need to let the cooling goo "burn in?"

 

[Elixer]

Just how much "goo" did you use?

There was a thin layer on the heatsink pre-applied.

After ~10 minutes of Prime95 it seems to be solid at ~60C.

Not sure what to think of this.

I assume your running stock speeds? If so then 60c at load for stock seems rather high, especially with an aftermarket cooler. If your overclocked then those temps sound right where they are supposed to be depending on the OC.

Those are pretty close to my 2500K temps at 4.2GHz with a Freezer 7 Pro Rev.1

This is totally stock clocks.

and after going to sleep and waking up after 20 minutes of Prime95 now its only going to 55C.

Man this thing is confusing me.

I'm using a pretty good aftermarket cooler and I get stable load temps under prime95 of 67c-70c. That's with an overclock of 4.2 ghz and a negative 0.020 voltage offset. That's far higher than a lot of people have been reporting. I'd bet that my temps would be as high or higher than yours at stock speeds as well.

I've tried two different well-reviewed heatsinks and multiple remounts using different methods of applying thermal paste and I can't get a significant reduction in temperature.

My only conclusion is that the general cooling and airflow of my HTPC case is lacking. (2x60mm rear fans + 1x80mm front) This could be your problem as well. I'm looking into mounting an additional downward blowing fan into the top of my case right now. We'll see how that goes.

I have the same mobo and my 2500k idles around the same amount according to the motherboards sensor. I just ignore that number though and check the core temperatures. While the motherboard says its 40 degrees my cores are only 25-30C downclocked at idle.

Getting rid of the Arctic Cooling MX-2 and applying Arctic Silver 5 has dropped my temperatures at idle to ~32-34C and my load temps to ~55C, this is after instantly applying it and allowing no burn-in time at all.

MX-2 is actually better than Arctic Silver 5 in terms of thermal performance. However, if you just used the MX-2 that was pre-applied on your heatsink, then you used WAY too much (which hurts thermal performance).
