For example, if your measured Ambient is 4C above Standard, subtract 4C from your reported Core temperatures to normalize your test results. Winter climates create below normal Ambient which increases overclocking headroom. For example, if your measured Ambient is 4C below Standard, add 4C to your reported Core temperatures to normalize your test results. Core temperatures normalized to Standard Ambient are your baseline temperatures. Establishing a baseline is important because as Ambient changes, if you maintain your hardware configuration and BIOS settings, a baseline gives you a consistent point of reference.
Test: Run Prime95 v Use Core Temp to measure your Core temperatures. Core temperatures in the mid 70's are safe. This means deviations between the highest and lowest Cores may be 10C, so "Average" Core temperature is often more realistic.
Note : When viewing your temperatures in Core Temp, values which reach 81C or higher will change from black to amber , which indicates caution.
Normalize your results to Standard Ambient and record the values for future reference. Section 14 - Thermal Testing Idle Look closely at the SpeedFan Charts above, where idle temperatures are shown between load temperatures. Note that some Cores have more "range" than others and idle lower.
Sensors can be tested with Real Temp. Core temperature sensors are more accurate at high temperatures for Throttle protection, so idle temperatures may not be accurate. Setup: In addition to using the previous Setup in Section 13, Speedstep and all "C" States must be enabled to achieve the lowest possible idle temperatures. To check this, click on Control Panel, Power Options, then to the right of the selected plan, click on Change plan setting. Next click on Change advanced power settings, then drag the scroll bar down.
If it's not, then correct it and click Apply. Reboot into Windows and confirm that your rig is at dead idle ; no programs running, and off line. Test: Allow your rig to "settle" for 10 minutes, then use your thermometer to measure Ambient.
Results: Core i 2nd through 6th Generation processors should idle at less than 8C above Ambient. Certain Previous Generation Core i variants and Legacy Core 2 processors may idle several degrees higher. Better cooling and lower idle power produce lower idle temperatures. When finished testing, restore your system to it's previous configuration. Section 15 - Improving Temperatures Whether your computer is a stock workstation or an overclocked gaming rig, achieving the lowest possible temperatures always depends on components, configuration and airflow.
If you want to overclock then upgrade your cooler. Auto applies excess voltage which means more power and heat. Linear flow cards exhaust heat from the case. Linear cards work well with an air cooled CPU. Axial cards dump massive heat in your case. Use zip-ties, patience and attention to detail.

Hey guys, so it is said that the Tcase sensor is located inside the IHS and measures its temps, but IHS is a piece of copper thats separated from a processor so how the hell does it transfer temperature data to it?
And where the hell really is that sensor? U can just take IHS off and there are no contacts with cpu whatsoever so how can the temps be read? CompuTronix Intel Master Moderator. Nov 13, 6, 31, Core temperatures are measured at the heat sources near the transistor "Junctions" inside each of the Cores.
When users look up their processor's Thermal Specification at Intel's Product Specifications website, they often don't realize what Tcase actually means. Since there are many software utilities for monitoring Core temperature, users unknowingly assume Tcase must be Core temperature.
Core temperature Tjunction is considerably higher than CPU temperature Tcase due to differences in the proximity of sensors to heat sources For lab testing only , a groove is cut into the surface of the IHS where a "thermocouple" is embedded at the center , which measures the temperature of the entire CPU. This is the temperature shown in BIOS, and on some recent motherboards is displayed on the two digit "debug" display.
Sedivy Estimable. Dec 17, 2, 0 3, No it's likely located on the motherboard, as close to IHS as possible, and approximates the true temperature. Cus i dont really see other reasons for calling it critical temp on their website besides that it throttles in their lab. And then they remove the sensor and ship the cpu to us? So that Tcase is kinda useless to us that may be a reason why they removed it in the 7th gen cpu specs on their site.
Profanity is strictly forbidden! Tj Max has always been the limiting Thermal Specification; not Tcase. Intel does not install, test, then remove a Tcase sensor from retail samples and ship them out to buyers. But yes, you're right; Tcase is a useless spec except to developers of cooling solutions.

I just went across to Intel forum and read all about i5 K and i7 K and I was not surprise that Intel had reply to someone on the forum to warn others not to exceed "Maximum Tcase" temperature of One person doing 80C on all cores and the cpu had died within a few months because the chip is 32nm not 45nm.
