DX48BT2 CPU Fan Suddenly Running at Top Speed

Jump to solution

Hi folks. The CPU fan on my DX48BT2 is suddenly running at top speed. When in the bios setup, the hardware monitor says that CPU temperature is 0 degrees or, I am assuming very hot without any reserve. The Intel Desktop Control Center says that the CPU delta T is 127 and the needle is pegged counterclockwise indicating a very low temperature. The processor in the system is an Intel Core2 Extreme CPU X9970 @ 3.20 GHz and is running at about 8 percent load.

I've tried re-updating the bios and restoring every thing to optimum default in the bios. Any idea where I can start looking for a solution? Thanks in advance.

Hello Joe,

It looks like the BIOS in the motherboard is not recognizing the real temperature of the processor, perhaps as a safety mode the fan will spins at 100% all the time.

If by updating the BIOS and loading default settings didn't fix the problem, I will recommend to you to contact the Intel® technical support at 916 377700 in order to get warranty over your motherboard.

The following link will show you the BIOS versions we have available for that motherboard:
