So I recently got my new APU-based system "running." Everything's going pretty well...performance is in-line, overclocks quite nicely, etc. The only problem is, none of the programs that I've tried displays the correct CPU temperatures - not even the one my motherboard manufacuturer gives!!
First, here are the system specs (an example to all you newer people):
Pre-Built PC Brand / Model if rig is a DELL/COMPAQ/ACER etc : Custom built
Motherboard: Gigabyte GA-A75-D3H
CPU ( Brand / Model / Is the computer Overclocked, if so list CPU speeds, FSB, Memory speeds, Voltages etc. etc.): AMD APU A6-3670K w/ stock heatsink (tried both stock speeds & overclocked up to 3.2GHz. overclocked only using multiplier, voltages are all stock/default except CPU voltage is at ~1.47v)
RAM ( Brand / Model / Tell us the number of sticks and if you´re using different brands): 8GB (2 X 4GB) Corsiar Vengeance DDR3 1600MHz @ 7-8-7-21-1T 1.5v CMZ8GX3M2A1600C9B
Video Card ( Brand / Model / Is it overclocked, and if so, to what speeds and using what utility ): None. currently using the APU's HD 6530D (overclocked to 500MHz Core...memory is 800MHz [RAM frequency])
PSU ( IMPORTANT !!! Brand & Model / Link to webpage with specs / manufacturer's website or picture of unit label ): Corsair TX850 850W (the one from my Phenom II X6 1090T system (sig) as the PSU for this APU has not arrive yet)
Monitor ( Brand / Model / Connection used): Acer G215H, using DVI connection
Hard drives: Hitachi Deskstar 320GB SATA2
Optical Drives: LiteON DVD-RW
Additional PCI cards: None
Number of fans present: Cooler Master HAF 912. 200mm at bottom-front (intake), 200mm at top (exhaust), 140mm at side panel (intake), 120mm rear (exhaust)
PLUS the following:
Operating System : Windows 7 Ultimate x64
Video Card Drivers in Use ( and tried ): 12.3 with CAP1
Motherboard Drivers Used: using BIOS version F4 (F5a is a beta BIOS). All LAN/USB drivers are latest on Gigabyte's website.
Apps/Games causing issues ( and if they've been patched ): HWMonitor, AIDA64, CoreTemp, EasyTune6, AMD OverDrive, HWinFO64 (all latest versions)
All major components check 100% after thorough testing ( eg. Memory & Memtest86 ): Ran tests with Prime95, 3D Mark 11, 3D Mark vantage, and Starcraft II
System clean of viruses / spyware etc: Fresh install of Windows with...pretty much an empty drive (programs / tools I installed)
Other things tried: contacted Gigabyte support (currently discussing with them), tried other computer forums, looked into APU reviews...
With that out of the way...
when idling in the BIOS, the CPU temperature is indicated to be, in my case, 20 / 21*C. The System temperature is 24*C. Room temperature is about 18 / 19*C.
In Windows, letting the system idle, CoreTemp, HWMonitor, and HWinFO64 will show the CPU temperautre to be 0*C, 1 / 2*C, or even negative!!
EasyTune6, and AMD OverDrive will show 9-11*C for CPU temperatures.
In all the programs used, the System temperature matches the 23/ 24*C from the BIOS.
If I get the CPU "working" and EasyTune shows 22*C, HWMonitor / HWinFO64 will show 12*C for the CPU temperature.
I'm beginning to think that the temperature in BIOS is correct. OverDrive, and EasyTune are off from what BIOS is readign by ~10*C. HWMonitor, CoreTemp, HWinFO64 are off of EasyTune / OverDrive by 10*C.
To simplify...BIOS is probably correct. (Comparing to BIOS), EasyTune / OverDrive is off by 10*C, HWMonitor (and others) is off by 20*C (hence the zero or less reading).
