  1.     What is TjMax?
  2.     Tjunction Max (TjMax) is the maximum temperature the manufacturer has rated their processor at. This value represents the maximum temperature the hottest part of the processor core should not exceed.
  3.     This value should not be confused with the TCaseMax rating, which indicates the maximum temperature the top-center of the processor's heatspreader should not exceed.
  4.     If your CPU is rated for 100C TjMax, and it was nearing the 100C value in the temperature fields, that is a sign of overheating. The temperature should not exceed this value, or it may cause instability and shorten the life of the CPU.
  5.     A rule of thumb dictates that a safe temperature is around 20C under the TjMax under full load.
  7.     Should I get the 32bit or 64bit version?
  8.     If you are not sure which version to get, my suggestion is to get the installer. It will install the correct files for your system, this way you don't have to worry about it.
  9.     If you still prefer to download the standalone version then you can select the proper download the following way:
  10.     If you have a 32bit OS, then the 32bit version is the only one that's going to work.
  11.     On a 64bit OS, both version will function, but since the 64bit version is native for the OS it should run faster - or more efficiently, and this is my recommendation.
  12.     32bit OS - 32bit Core Temp.
  13.     64bit OS - 64bit Core Temp.
  15.     I can only see a single temperature reading.
  16.     AMD processors based on the Phenom and Phenom II (Athlon II, Sempron II, Turion II, etc.) only have a single thermal sensor.
  17.     Thus Core Temp will only report a single CPU temperature reading. There is no way of getting a per-core reading on these CPUs.
  19.     Why does my AMD processor's temperature always reads 0C/32F?
  20.     On older processors based on the Athlon 64 core (K8) this is usually caused by a problematic processor, this is a pretty uncommon issue.
  21.     On CPUs starting with the Phenom architecture AMD has introduced the ACC function, it allowed the early Phenoms to achieve higher overclocks, and on the Phenom II based processors it allowed unlocking of extra cores and L3 cache.
  22.     Some motherboards include a Core unlock feature, which is based on ACC as well.
  23.     In most cases disabling these features in the BIOS will bring temperature readings back.
  25.     Why is the temperature of my Phenom based processors lower than the ambient temperature?
  26.     Starting with the Phenoms, AMD's digital sensor no longer reports an absolute temperature value but a reading with a certain offset, which is unknown. It is estimated that this offset is between 10 - 15c.
  28.     What is the G15 applet in the Tools menu?
  29.     The G15 applet is designed to be used with the Logitech G15 and G19 keyboards. It displays Core Temp data on the keyboard's LCD display.
  30.     On systems not using the keyboard, this applet is always disabled.
  32.     Why does Core Temp requires administrator privileges to run?
  33.     Core Temp requires direct access to hardware to be able to read temperature and other processor information.
  34.     In Windows you can only access hardware using a kernel mode driver. Since Core Temp doesn't install anything on your system, it loads the driver at run time, this requires administrator rights to achieve.
  36.     I have just downloaded a new version of Core Temp and now my anti virus software has flagged it as containing a virus or trojan!
  37.     Core Temp does not contain a trojan. Core Temp contains 2 driver binaries (32bit and 64bit) inside of the executable, Core Temp extracts the drivers and starts them at run time, as discussed above. This may bring up a red flag in some antivirus scanners triggering them to believe that Core Temp contains a virus or trojan code.
  38.     Usually AV companies patch this kind of thing up very quickly and the warning goes away after an update.
  39.     My systems use the latest updates of AV software and the files are scanned before being brought online on Most other respectable download sites use protection as well and scan the software before putting it online as well, but I can't vouch for anybody except me.
  41.     Why does Core Temp say that my processor is not supported?
  42.     Core Temp supports all AMD processors starting with the Athlon64 family.
  43.     Intel processors are supported starting with the Core series, Pentium 4, D, M and older processors do not have the required digital sensor integrated to allow Core Temp to properly function.
  44.     Same goes for the Xeon processors, only CPUs starting the Xeon LV (Yonah core), Xeon 3000 series and Xeon 5100 series and up are supported.
  46.     Core Temp doesn't display VID for my processor.
  47.     Voltage ID (VID) is not supported on any of Intel's new processor families, starting with the Core i7 series.
  49.     Core Temp reports incorrect vcore in the VID field.
  50.     VID is not the same as VCore. VCore is the actual voltage the processor is being fed by the motherboard.
  51.     VID is the recommended voltage the processor should be running at at the current power state, this is a predetermined value, programmed by the CPU manufacturer. When the processor settings, especially the VCore is kept at default settings, Core Temp will provide a good approximation of the real VCore, but if you change the setting using the BIOS or by other means, Core Temp's VID readings should be ignored.
  53.     Does Core Temp implement overheating protection?
  54.     Yes, please see the Options menu.
  56.     Does Core Temp allow to customize the system tray (Notification area) display?
  57.     Yes, please see the Options menu.
  59.     Does Core Temp support the new Windows 7 taskbar features?
  60.     Yes, please see the Options menu.
