Intel Temperature Guide CPUs. Intel Temperature Guide by Compu. Tronix. Updated 1. November 2. 01. 7Preface. The topic of processor temperatures can be very confusing. The purpose of this Guide is to provide an understanding of standards, specifications, thermal relationships and test methods so temperatures can be uniformly tested and compared. This Guide supports Core X, Core i, Core 2, Pentium and Celeron Desktop processors running Windows Operating Systems. Sections. 1 Introduction. Ambient Temperature.

Intel Desktop processors have temperatures for each Core and a temperature for the entire CPU. Core temperatures are measured at the heat sources near the transistor Junctions inside each of the Cores where temperatures are highest. CPU temperature is instead a single measurement centered on the external surface of the CPUs Case or Integrated Heat Spreader where the cooler is seated. Core temperature is considerably higher than CPU temperature due to differences in the proximity of sensors to heat sources. Fil. 5t. jpg. The Thermal Specification for Core temperature is Tjunction which is also called Tj Max Temperature Junction Maximum or Throttle temperature. The Thermal Specification for CPU temperature is Tcase Temperature Case which is a factory only measurement. Tcase and Tjunction Tj Max Thermal Specifications are both shown in Intels Datasheets, which include all specifications, definitions and technical descriptions. However, Intels Product Specifications website should be viewed as a quick reference, since it only shows the Thermal Specification for Tcase or Tjunction Tj Max, but not both. The Thermal Specification for 7th and 8th Generation processors is Tjunction Tj Max, but for 6th Generation and all earlier processors its Tcase. Heres where processor temperatures get confusing Since there are numerous software utilities for monitoring Core temperature, when users look up their processors Thermal Specification at Intels Product Specifications website, many dont realize what Tcase actually means, and assume it must be Core temperature. Tcase is not Core temperature. Intel has no documentation which describes the relationship between specifications and temperature that makes sense to the average user, so explanations are given in Section 7. In order to get a clear perspective of processor temperatures, its important to become familiar with the terminology and specifications. Use CPU Z to identify your processor CPU Z http www.

Section 2 Ambient Temperature. Also called room temperature, this is the temperature measured at your computers air intake. Standard Ambient temperature is 2. C or 7. 2F, which is normal room temperature. Ambient temperature is a reference value for Intels Thermal Specifications. Knowing your Ambient temperature is important because all computer temperatures increase and decrease with Ambient temperature. Use a trusted analog, digital or infrared IR thermometer to measure Ambient temperature. Heres the temperature conversions and a short scale http imgur. TX6. Bvm. jpg. When you power up your rig from a cold start, all components are at Ambient, so temperatures can only go up. With conventional air or liquid cooling, no temperatures can be less than or equal to Ambient. As Ambient temperature increases, thermal headroom and overclocking potential decreases. Section 3 CPU Temperature. Also called Tcase, this is a factory only temperature measured on the external surface of the Integrated Heat Spreader IHS. Tcase isnt tested on retail processors, but for lab testing only, engineering samples are used. I ran the Intel Diagnostic Tool before posting here, but I ran it again. The processor passes those tests. I can leave the system idle and whenever a background. Grab the latest updates, manage your OCZ SSD with SSD Utility, and explore OCZ SSDs for your laptop or PC.

The thermal copper pillar bump, also known as the thermal bump, is a thermoelectric device made from thinfilm thermoelectric material embedded in flip chip. Download Intel Power Thermal Utility' title='Download Intel Power Thermal Utility' />A groove is cut into the surface of the IHS where a thermocouple is embedded at the center. The processor is installed, the stock cooler is seated, the thermocouple is connected to measurement devices and the temperature is then tested under carefully controlled conditions. Tkv. D. jpg. For retail processors, one of two different methods are used to display CPU temperature in BIOS and in monitoring utilities. Previous Method Processors for Core 2 Socket 7. Core i Socket 1. 36. Analog Thermal Diode centered under the Cores to substitute for a laboratory thermocouple. The Analog value is converted to Digital A to D by the motherboards Super IO Input Output chip, then is calibrated to look up tables coded into BIOS. For these processors, the monitoring utility provided by your motherboard manufacturer on the Driver CD displays CPU temperature in Windows. Accuracy can vary greatly with BIOS updates, so CPU temperature can be grossly inaccurate. Present Method Processors for Core i Sockets 1. Core X Socket 2. 0xx dont use an Analog Thermal Diode, but instead substitute the hottest Core for CPU temperature, which is a confusing contradiction in terms. This is the temperature shown in BIOS, and on some recent motherboards is shown on the debug display. For these processors, the monitoring utility provided by your motherboard manufacturer on the Driver DVD displays CPU temperature in Windows, but is actually the hottest Core. Regardless of the Method used, CPU temperature in BIOS is higher than in Windows at idle, because BIOS boots the processor without power saving features and at higher Core voltages to ensure that it will initialize under any conditions. Note The term CPU temperature is commonly misused as a general term for any processor temperatures. Section 4 Core Temperature. Also called TjunctionTemperature Junction, this is the temperature measured at the heat sources near the transistor Junctions inside each Core by individual Digital Thermal Sensors DTS. As such, Core temperature is a specific term. Rl. K. jpg. Since the Digital Thermal Sensors DTS are located at the heat sources where temperatures are highest, and the factory temperature measurement on the Integrated Heat Spreader IHS is not, theres a temperature difference or gradient between DTS and IHS locations. At 1. 00 workload or Thermal Design Power TDP, the gradient on Core 2 and Core i processors through 2nd Generation is about 5C, but the gradient on 3rd through 8th Generation can be up to 2. C. For details see Section 9 The TIM Problem. Core temperature is the standard for thermal measurement. Intels specification for DTS accuracy is 5C. Although sensors are factory calibrated, deviations between the highest and lowest Cores can be up to 1. C. Sensors are more accurate at high temperatures to protect against thermal damage, but due to calibration issues such as linearity, slope and range, idle temperatures may not be very accurate.
