Core Temp is a compact, no fuss, small footprint program to monitor CPU temperature.
Now Vista ready! (x86 and x64)

The uniqueness of it is that it shows the temperature of each individual core in each processor in your system! You can see in real time how the CPU temperature varies when you load your CPU. It's also completely motherboard independent.

Intel and AMD recently published detailed, public information about the "DTS" (Digital Thermal Sensor), which provides much higher accuracy and more relevant temperature reading than the standard thermal diode sensors do. (How does it work?).

This feature is supported on all Intel Core and Core 2 based processors as well as the whole AMD's Athlon64 line of CPUs. For a full list of supported CPUs see the CPU Support List.
Note: AMD Phenom is supported, but it does not report absolute temperature. More on this in How does it work?.

Core Temp also has a logging feature, allowing a user to easily record the temperature of his processor(s) over any period of time, then the data can be easily transferred into an excel datasheet for easy graphing.

Core Temp works on Windows 2000, XP, 2003 and Vista (both 32bit and 64bit versions).
Thanks to CoolIT Systems for providing a digitally signed Core Temp driver which now works on all Vista versions.

New feature in Core Temp 1.0: Plug in system
I have started to work on a new feature aimed at developers for Core Temp.
I've been talking about shared memory in the previous release, and although that gives some flexibility in creating Core Temp add-ons, it doesn't make the 3rd party software an integral part of Core Temp.
The plug in system changes that as it will allow any programmer with an idea for a new Core Temp feature\extension to create one, add it to Core Temp and the plug in becomes a part of it.

Starting with version 0.99, Core Temp implements "Shared Memory" allowing developers access to temperature readings and other CPU statistics provided directly by Core Temp.
Dynamic Link Libraries (DLLs) are supplied for both C++ (and other unmanaged languages) and .NET Framework 2.0, allowing easy access to the readings without having to write any shared memory related code.
For more information, please visit the Developers page.

Version 0.99.3 - 22th August, 2008

- Add: Correct TjMax values for 45nm Core 2 series, according to this document.

- Fix: When TjMax = 0 (undefined) "Delta to Tjunction" was not added to the temperature string.
- Fix: On the fly CPU speed didn't pick up changes when EIST was disabled (only C1E active).

Version 0.99.2 - 18th August, 2008

- Fix: Start with Windows option was broken in 0.99.1.
- Fix: Default color for the second system tray icon is invisible with WinXP blue theme.
- Fix: Save screenshot function would create a corrupted BMP in some viewing software.
- Fix: Nehalem does not report VID like earlier CPUs. VID field now disabled for Nehalem.
- Fix: Incorrect 65nm Turion X2 code name detection.
- Fix: Potential bug of improper K10 and up recognition.
- Fix: Enabling distance to Tj.Max with "Highest temp." for system tray would show the largest distance to Tj.Max instead of smallest.
- Fix: Vendor ID and Device ID values were reversed in the register dump file.
- Fix: 3/4 temperatures logged for Phenom X3/X4 instead of 1.

- Add: Support for Core Temp plugins. (Still in beta phase and not in GUI yet).
- Add: Full support for AMD's Puma platform CPUs (in previous version reffered to as Griffin).
- Add: Initial support for 45nm AMD processors.
- Add: Update K8 and K10 recognition code to support all currently known CPUs.
- Add: Default TDP detection for Nehalem.
- Add: On the fly CPU speed detection.
- Add: Close to system tray option.

- Change: Log file is now produced in CSV format - easily import your logs into Excel.
- Change: Logging interval is now in Seconds instead of miliseconds.
- Change: Default logging interval is now 10 seconds.
- Change: Logging is now off by default.

Version 0.99.1 - 10th July, 2008

- Fix: Layout when using upto 125% DPI.
- Fix: Layout problem and extra systemtray icons with Phenom.
- Fix: Potential crashes while saving a register dump file.
- Fix: Core Temp icon wasn't showing in About box.
- Fix: Menu shortcut keys were not available for all menu items.
- Fix: A few old unnoticable bugs.

- Add: Initial Intel Nehalem support.
- Add: Initial support for AMD's Griffin cores - Untested.
- Add: Improved Intel Atom support.
- Add: Support latest AMD K8 CPUs.
- Add: Support for HyperThreaded CPUs. Core Temp will only display the physical cores and average load on each core.
- Add: Support for Pentium E5000 series.
- Add: Display core and thread count per CPU.
- Add: GUI Adjustments of Temperature offset and G15 applet via the Settings window.
- Add: Create a screenshot function. Access from "Options" menu or by F9 shortcut.
- Add: Shortcut key for register dump file: F7.
- Add: Update register dump output: APIC ID, CPU number, Core number, Thread number.

- Change: Move all settings to the ini file out of the registry.
- Change: Rename ini file to CoreTemp.ini.
- Change: Temperature offset adjustment works for AMD CPUs as well.
- Change: Atom Tj.Max adjusted for more accurate readings.
- Change: Cleaned up code a little bit.

Version 0.99 - 18th May, 2008

- Fix: Incorrect recognition of 45nm Mobile Intel CPUs.
- Fix: CPU temperature not displayed in Core Temp window on Phenom CPUs (0.98 and 0.98.1).
- Fix: CPU load would sometimes display -1% load.
- Fix: AMD K8 would sometimes spike to 206C, the false reading is now ignored.
- Fix: AMD K8 sometimes constantly reads -49C.
- Fix: Core Temp does not show up automatically on G15 LCD with 2.02 driver.
- Fix: Shared memory structure was not properly filled on multiprocessor systems.
- Fix: System tray setting "Show highest temperature of each CPU" only displays one temperature reading in a multi CPU system.
- Fix: Certain problems with font resizing should now be fixed.
- Fix: G15 LCD would not update after using soft buttons.
- Fix: On temperature display mode change, high and low records were not reset.
- Fix: Changing the reading interval in settings did not actually update, restart of Core Temp was needed to apply the change.
- Fix: Incorrect VID detection on 45nm desktop Intel parts.

- Add: Shared memory - developers now have access to Core Temp data.
- Add: Register dump to text file function.
- Add: Preliminary Atom (Silverthorne) support - Untested.
- Add: Support for Intel Core 2 Duo E7000 45nm series.
- Add: Option to show a single icon instead of temperature in the system tray.
- Add: Custom font and size for G15 LCD screen or simply use the built in compact font and layout. (via Settings.ini)

- Change: Improved detection of L2 cache on Intel chips for more accurate recognition.
- Change: Rewritten temperature calculation to fix problems with shared memory.
- Change: Default G15 LCD text layout and font changed.
- Change: Doesn't create a log file containing session start and end times if logging is disabled.
