CPU Keeps Rising/Shuts off

Specs: Windows XP, Intel(R) Celeron(R) 2.8 /512MB RAM
• Purchased 2 identical Motherboards (Manufacturer Foxconn) supporting the new flat socket CPU with the pins on the motherboard instead of the CPU
• Purchased Intel(R) Celeron(R) - Used
• Purchased 2 identical Heat sinks and fan

• Monitoring Temp inside the BIOS
• Temp rises 1 degree per second
• CPU Temp continues to rise from 70 to 93 degrees Celsius then shuts off

• Some techs said try different memory, tried and that wasn’t the issue
• Foxconn Tech says that the CPU is getting hot and then shutting down, he is correct

Repair attempts:
• Old heat sink is secured, flush, and tight
• New heat sink is secured, flush, and tight as well
• BIOS settings set to tell the fan to cool at maximum settings

• Is it a bad CPU or could it be a bad version of a Heatsink and fan that I am using?
• How can this problem be eliminated?
• Do I need a new CPU or just an extremely cool heatsink and fan? It gets hot Way too fast.

It's got nothing to do with the RAM or anything else. If the CPU is running hot, you don't have the heatsink installed correctly. Applying just the right amount of thermal paste & properly securing the heatsink in place are critical to good cooling.

Follow these instructions exactly, regardless of the type of paste you use:

Thanks for your reply, i figured it out this morning that i needed more thermal paste, good thing i bought a new heat sink because it was included, but yeah you are 100% correct. Thanks again for your time...Such a small thing can make all the world of difference. i am running at about 60 Celsius now =)

yea, if your going up 1 degree/sec the cooling is flat out not working. the thermal paste makes sure the cpu actually transmits the heat. 60c isn't bad but is a bit hot for that CPU. If it doesn't drop to around 50 after the break in period you may want a better cooler. You also probably dont want to really stress your computer for a little while while the thermal paste sets. I run my comp for 3 days with a steady 1/4 load for break in.
