Cpu overheating 120 °C

Specs: N/A
i have just build myself a new computer, it is my first time building one but had no troubles with it. so i went to turn it on for the first time and it was all looking good until it suddenly turned off.

so i went into the bios and saw that it was at 120 degrees Celsius just before it turned off. i have no idea what could be causing this and i have gone through the manuals again to see if i have missed anything also i cant really look around in the bios to see if there is anything i can change because i only have about a minute before it shuts down.

i have found that when i take out the ATX 12v cord the cpu doesnt overheat but i need that cord in for the computer to boot up.

im wonder if somehow its reading the temprature wrong becuase it goes up to quickly and 120°C is insane.

cpu: i7 950
mobo: gigabyte ga-x58a-ud3r
psu: corair TX 750w
graphics card: 5850 toxic
6gb ram
antec 900 case

Did you use a thermal pad or thermal paste between the CPU and the heat sink?

Is the CPU fan working properly?

Verify you have the proper BIOS version installed to run the processor you have. Look at the 2 links below for information on both rev. 1 & 2.

it uses a single 12 v rail instead of several virtual rails with lower currents.

the cpu had some grey strips on it, my understanding is they melt when u turn it on and make the thermal paste. also i believe the fan is working properly. it says 2000 rpm in the bios but im not sure if that is what it supposed to do. i should probably take the heatsink off and see if anything has happened.

EDIT: i took the heatsink off and the strips have not melted which is weird for something that was aparently 120 degrees celsius.

There may have been a plastic seal on the thermal pad that you needed to remove. Does what you see look like plastic? I suggest you remove everything from both surfaces and apply thermal paste according to the instructions for your processor. Both surfaces must be thoroughly cleaned. Do not mark up either surface by scraping hard. The heat sink should have a polished look and the processor should also be smooth. Use solvents to clean off the residue. Lacquer thinner is what I use but there are other solvents that will cut the residue.

Next time, read the instructions.

Your CPU wouldn't even run at 120C.
