My core temps are getting scary, when the outside temperature is >90f, and my room air conditioner is not on.  If I were a rich man, I would run my A.C. 24x7, but usually shut it off when I am at work.   This past week, at a full loads, I have seen average core temps between 86 and 90 c, with a record high of 92 c!

What happens when a core gets to 100 c?  Does the pc shut down?  Does if Blue Screen?  Does the chip underclock itself?

Also, I was wondering if higher core temps require more vcore.  In the last few weeks, I have raised vcore up ( due to 101 BSDO's) up a few notches to 1.3125.  Can this have anything to do with the higher core temps, or is it just a coincidence?

Thanks

According to Intel 95-100 degrees is TJmax, ( Varies by chip) it is listed as the temp that catastrific falure can accure, Once TJmax is reached, A Timmer kicks in and the cpu downclocks to protect itself, If the temp of TJ max does not respond by the downclock withen a specific time, another threshold called T junction is met, and causes shut down usualy between 105 and 110, since it's a timed event, and not a threshold temp the # varries, 120 is the temp that selacon does break down. And damage WILL accure, all of these #'s are calculated estamates from various sources, as the actual #'s are intel trade secrets, but from my experance they are very close if not actual.

Well just make sure that you didn't disable thermal throttling in bios so it can save itself when it heats up.

My core temps were fine, until the weather was >85 f.

I assume TIM means thermal paste?  I used one of those metal strips.  I did a good job of aligning it.  If I make through the summer, I'll keep the air cooler.  If there are too many problems, I'll go to water cooling.  Any suggestions?

The ambient room temperature affects core temps more than I had expected.  

Metal strips? ****? Correct me if I am wrong, but I have never heard of this. You should be using nothing but a good Thermal Interface Material such as Arctic Silver 5. You can get a free sample of a very good TIM from this guy, Falcon_CMH:

Look first to understand how to apply:

YouTube: How Thermal Compound Spreads

(And I recommend looking at some of those others too.)

Your temps will rise near linearly with ambient temp (room temperature). So when your ambient rises 9*F your CPU temps will rise 5*C (with air cooling).


Also, I have had my CPU above 100C! It was due to an E-Leet malfunction. When your CPU reaches 100C the multiplier (core) drops to downclock the CPU. I seen mine drop to 10x (with Speedstep off, I was horrified). So there is an automatic protector, reaching 100C will not 'break' your CPU. However, the life expectancy may be affected.

I have never heard of higher temps requiring higher Vcore. How long has it been since you blew out the dust from your case and cooler(s)? I just blew mine out, it had only been 2 mos and there was a lot! I was amazed as how quickly the dust gathered. It really does make a big difference in cooling.

I just wanted to re-emphasize this post. I have actually been using the spread method for so long. wow. It used to be the accepted method for years...Let's change that and see if there is any effect. Not being able to raise Vcore past 1.27 is really a pain in my butt.
