Hi Guys,

been dealing with computers for 12 years now and this is the first this has happened,

I was change around case fans and put them in the designated slots on the motherboard, fired up the computer and one of the case fans cable glowed red and was melting but now when I switch my computer on at the bios i get " MB TEMPERATURE ERROR" but the computer boots fine.

Under the T_SENSOR1 in the bios I am getting a reading of 127c but the computers runs fine, the CPU idles at 34c and the graphics card is 42c idle.

Done the usual of IT basics, as i have been building computers for 12 years.

it is worrying me seeing that temp, can someone shed some light please?

I am making a guess here but seeing that you melted a fan lead that is a good indication of a hard short in the fan. So I would be guessing that the temperature probe on that header (if it is a 4 pin PWM header) probably got fried as well. The best thing to do is remove the motherboard and inspect the back side of it for burn marks. You will need good lighting and possibly a magnifying glass if it is a small burn mark.

My guess is that you will need a new motherboard.
