Great, I'll give that a try. Thanks Fiery.

I see you have the same mobo and CPU, Stasio. The temperature difference between your mobo CPU diode and CPU package is 16C(CPU-24C, CPU Package-40C). My relationship here is 18C (CPU-16C, CPU Package-34C), I still have the stock cooler and I see you have a water cooled setup. The ambient air temp in the room where I keep my PC is quite chilly which is why my System temperatures are so low. I have heard that these temperature diodes can become quite inaccurate when they get into the lower portion of their operating range. Perhaps due to the cooler temps, I am in a slightly less accurate range of the mobo CPU temp. When I stress my system and bring up my CPU package and system temps to a more normal area, my mobo CPU temperatures get much more reasonable. It seems that at least with the our setup, the motherboard CPU diode will always read approx 15C less than the CPU Package temperature. My issue is that at idle in my cool room, my CPU package temperature is often 30C or less, putting my mobo CPU temp into temperatures that just don't make sense. I wonder how GIgabyte calibrates these diodes and if the temperature sensors can't correctly read when colder than average.

Hi, Just installed AIDA64 and I am absolutely loving it so far. I have noticed an issue with one of the temp reading however. The "CPU" temperature reporting from the motherboard CPU sensor is providing inaccurate readings. Right now its reading 12C while ambient temperature in the room is more like 18C (around 24 in the case). Temperatures off the CPU are reading correctly at around 34C (CPU package, Core 1,2,3,4) Its an intel 3770k by the way. In Bios, the CPU temperature reads a correct 31-35 which I believe to also be coming from the motherboard CPU sensor. (This should match "CPU" temp in AIDA I believe) Because the BIOS temp is correct, I don't see this being a motherboard or CPU issue. Is this an issue with how AIDA64 is reading the mobo cpu temp? I have attached a screen shot as well as the ISA Sensor Dump here: Thanks for the help. P.S. I saw where someone asked for a comparison using Gigabyte Easy Tune 6. ET6 is also reporting the same 12C CPU temperature! I guess this may not be an AIDA issue... ------[ AIDA64 v2.85.2400 ]------ ------[ Microsoft Windows 8 Professional with Media Center 6.2.9200.16551 (64-bit) ]------ ------[ Motherboard Info ]------ Motherboard ID : 63-0100-000001-00101111-122211-Chipset$Z77X-UP5_BIOS DATE: 09/03/12 13:40:53 VER: 04.06.05 Motherboard Model : Gigabyte GA-Z77X-UP5 TH-CF Motherboard Chipset : Intel Panther Point Z77, Intel Ivy Bridge DMI MB Manufacturer : Gigabyte Technology Co., Ltd.
