I had a defective motherboard. The front fans would ramp to top maximum speed with no real reason. I replaced EVERYTHING except the motherboard. Still same trouble. Then a "tested" mb from ebay. That tested mb did the same exact same thing! I ordered yet another mb that was described as a factory original NEW unused mb that had been tested. Upon testing with the new mb, I find that all is fine now. I am wondering why the computer is still displaying the error that two different fans are defective. They are not defective. I replaced them all and they work fine. Does bios write logs to hard drive? If not them I must be in the twilight zone...
