Discrepancies among core temperatures

post #1 of 5
Thread Starter 
My i7-2600K at stock speeds has loaded core temperatures of 57, 62, 64, and 60 degrees Celsius. I understand that discrepancies among different cores are normal.

My question is how this relates to Intel's maximum recommended temperature of 73. Should I be concerned as soon as Core 3 (now max 64) reaches 73, or will it throttle down until the other cores even out? Is my wiggle room for overclocking 9 degrees (73 - 64), 16 degrees (73 - 57), or something in-between?

Depends. Most systems will have the PC auto shut down when the temps reach to absolute dangerous levels. These usually lay within 85C+.

Based on the impression, I don't think you have good cooling. Sounds like you are using a stock cooling where the paste has not bin applied properly. That tends to be the main reason why you see core temps be at around 7 C differences; which in my opinion, I think it is pretty bad; especially when you are wanting to overclock.

If you want to overclock on the stock cooling you can't push far. It might be a good means to test; you could practise on a 100-200 MHz overclock to see if you are willing to push the CPU. Your....pretty much.... only threat to overclocking is temperature. Even voltages don't matter that much. Temperatures is your biggest threat. Keep those as low as possible.

The maximum temperature Intel specifies is the tCase, not the TJMax.. So it is not the maximum temperature for the cores themselves but rather the IHS ontop of the CPU. Unless you implant a diode into the IHS it's impossible to read the temperatures for it. The TJMax for sandybridge is 98C however, which is the maximum temperature for the Cores themselves.

It's a Hyper 212 Plus with an extra fan for push/pull. I initially used Arctic Silver 5 but redid it with the included paste from CoolerMaster. Temps were the same. Never tried the stock cooler. Idle temps are just 1 - 3 degrees above room temperature (80 F / 27 C). Thanks for the info/suggestions.

You can turn HT off I'm sure that will help a lot with temps for overclocking. In that case though you would have been better off with an i5 2500k.
