Hello all. I have two temperature sensor programs: Sandra and MBM5. Sandra gives me temperature readings of: board temp. : 28C CPU temp. : 19C MBM gives me: board temp.: 28C CPU temp. : 72C When I run MBM first then Sandra "together", suddenly Sandra starts giving me values similar to MBM. But if I run Sandra alone before running MBM, it gives me the low nice values up there. I realized something was wrong with the sensors so I restarted, checked temperature from BIOS and this what it gave me: system temp. : 32C CPU temp. : 33C FAN: 2600RPM System fan: 0RPM Temperature from BIOS conflicted with the sensor programs. However I noticed that "the system fan" isnt working. Now I'm not sure what the "system fan" is since I didnt even know I had one. All I know is the heatsink and the fan on top of it is working and another fan at the back of my pc case is also working. SO how can it be '0 RPM'? Also what can I do to Sandra and MBM? Why would MBM give false values? Is it possible that both programs conflicted or is it possible that a virus might be causing my CPU to "think" that its temperature is high even though it's not? Because I touch my heatsink and its relatively cool, somewhere in the 20's for sure. Please note that I cleaned my heat sink and my fan yesterday and let it cool down for the night and as soon as I installed it this morning and turned on my pc it gave me the "70'C" which is impossible seeing that I just turned on the system and nothing was even done yet. Please help, I'd appreciate it. UPDATE: I set an alarm in my BIOD for CPU temperature at 60C, saved and exited. Loaded Windows just fine and no alarm was sounding. I opened MBM and the alarm went on, just as I opened the program... Any clues?
