Hello,
I'm running the following desktop box:
Motherboard: Gigabyte GA-P35-DS3L
CPU: Intel Core 2 Quad Q9550,Boxed, Q9550, Socket 775
Video card: Asus Radeon HD4870,GDDR5, PCI Express x16, 512MB
Memory: 8GB DDR2 (Kingston KVR667D2N5/2G, 2048 MB, DDR2, PC5300, 667 MHz x 4)
Box: Cooler Master CM 690
Power Supply: Cooler Master Real Power M620,Retail, 620Watt
I looked into my BIOS, which has all default values set by Gigabyte:
HDD S.M.A.R.T. Capability (Disabled)
Limit CPUID Max. to 3 (Disabled)
No-Execute Memory Protect (Enabled)
CPU Enhanced Halt (C1E) (Enabled)
CPU Thermal Monitor 2 (TM2) (Enabled)
Virtualization Technology (Enabled)
SATA AHCI Mode (Disabled)
SATA Port0-1 Native Mode (Disabled)
ACPI Suspend Type (S3(STR))
Soft-Off by PWR
HPET Support (Enabled)
HPET Mode (32-bit mode)
CPU Smart FAN Control (Enabled)
CPU Smart FAN Mode (Auto)
Robust Graphics Booster (Auto)
CPU Clock Ratio (6X)
Fine CPU Clock Ratio (+0.5)
CPU Frequency (2.16Ghz, 333x6.5)
CPU Host Clock Control (Disabled)
CPU Host Frequency (333)
PCI Express Frequency (Auto)
C.I.A.2 (Disabled)
Performance Enhance (Turbo)
System Memory Multiplier (SPD) (Auto)
Memory Frequency (667)
System voltage control (manual)
DDR2 overvoltage control (Normal)
PCI-E OverVoltage Control (Normal)
FSB OverVoltage Control (Normal)
(G)MCH OverVoltage Control (Normal)
CPU Voltage Control (Normal)
Normal CPU Vcore (1.02500V)
Now, here is the problem. In BIOS, my CPU temperature is 84 degrees celcius. System temperature is 41 degrees celcius. When I login to windows 7 and use CoreTemp, I see that all 4 cores are at about 55 degrees celcius, where the highest value is 66 degrees celcius. Notice that this is with casual browsing, I am not running arithmetic heavy applications whatsoever.
Why would my CPU be so hot while my PC is idle, and why so much hotter (84 degrees) in the BIOS?
I think I have positive air pressure in my box, there is 1 fan sucking air in at the front. The bottom power supply has a fan at the bottom. Then there are two fans sucking air out, one at the top of the back and one at the rear end of the top of the case.
Note I am a newbie to these things. I have no idea what these BIOS settings mean nor if they are setup correctly.
Could anyone help me with my temperature issue and/or inform me of any possibly "stupid" BIOS settings?
Thanks a lot.
Kind Regards,
Tom
