Core Temp is a compact, no fuss, small footprint program to monitor CPU temperature.
Now Windows Vista and Windows 7 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 XP Service Pack 2, 2003 Server, Vista and Windows 7 (both 32bit and 64bit versions).
Thanks to CoolIT Systems for providing a digitally signed Core Temp driver which now works on all Vista and Windows 7 versions.

New Core Temp Gadget and Windows Media Center addon for Windows 7 and Vista.
Recently I've released a new version of the Core Temp Gadget, completely overhauled.
The new version includes a graph view, listing processor load or temperature as well as memory utilization.
The readings are now color coded and they are user adjustable from the Options screen. Among these improvements the gadget can be resized and the information text above the readings can be hidden if so desired.
You can download Core Temp Gadget and CoreTempMC from the Add Ons page.
User feedback is important and you can leave yours right at the Live Gallery page for the gadget.

CoreTempMC is a Windows Media Center add-on for Windows 7 and Vista. It allows you to view information from Core Temp right from the Media Center interface using your remote. In addition it also displays the memory utilization.

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.
