Although Intel processors are capable of operating above 90C, we also know that excessive heat kills electronics. Throttle Temperature, also called "Tj Max" (Tjunction Max), is the Thermal Specification that defines the Core temperature at which the processor will Throttle (reduce clock speed) to protect against thermal damage. Tjunction (Core temp) = 77C <- This is your spec. All values are based on Intel documentation. The relationships between Ambient temperature, CPU temperatures, Core temperatures and Throttle temperatures are shown below. The relationship between Core temperature and CPU temperature is not in the Thermal Specifications it's only found in a few engineering documents. ![]() Tcase + 5 makes the corresponding Core temperature 77C. Intel's Thermal Specification is "Tcase", which is CPU temperature, not Core Temperature. A single Analog sensor under the Cores measures overall CPU temperature.Ĭore temperature is 5C higher than CPU temperature due to sensor location. Heat originates within the Cores where Digital sensors measure Core temperatures. Intel desktop processors have thermal sensors for each Core, plus a sensor for the entire processor, so a Quad Core has five sensors. You need to read this Tom’s Sticky: Intel Temperature Guide. Use an "X" pattern, so as to apply even pressure during installation. (4) If you're re-seating the entire cooler, then be sure to latch the pins across from one another, rather than next to one another. ![]() (3) While holding the leg firmly against the motherboard with one hand, you can now push on the top of the latch with your other hand until the latch clicks. (2) To get the pin fully inserted through the motherboard, push only on the leg, NOT on the top of the latch. (1) To re-seat a single loose push-pin, release the latch mechanism to the retracted clockwise position, then reset it to the counterclockwise position, but do NOT push on it yet. The push-pins can be deceivingly tricky to get them fully inserted through the motherboard and properly latched. When you see a significant drop, you've found the loose push-pin. You can troubleshoot this problem by pushing firmly on each corner of the cooler for about 30 seconds while watching your load temperatures. This causes poor contact pressure between the cooler and the CPU, resulting in high temperatures in BIOS, as well as in Windows at idle, and especially at 100% workload. ![]() If you're using Intel's stock cooler, then it's very likely it has popped a push-pin loose from the motherboard, which is a common problem.
