Okay so I am building a computer for a friend of mine and i bought the motherboard above. Upon assembling all of the parts, the CPU thermometer appears to be bugged. After 5 minutes, the BIOS shuts down the system due to an "overheat" of the CPU which is an Intel Core 2 Duo 3.0 Ghz.
Any help would be greatly appreciated.

Can you tell what temps it is reporting also verify that the heat sink is properly seated. I have heard of on occasions heatsinks having a flaw in the base that makes it partialy stick up, infact punched a hole in the CPU, thus not providing solid heat transfer and over ehating as well physical damage to the CPU. I would hold the heatsink manufacturer responsible for all the issues in this case. It may not be it could be faulty thermal detection in the motherboard. if you can test the temp with something external to see how much heat the base of the heatsink is getting.

Jeez Yojimbo ya beat me to it again :-P
So in addition to Yojimbos' post:
The E8400 requires thermal paste/grease so if you’re not using any, it would be a good addition. Stock heat-sinks usuall come with a patch of it already in place. Check that the heat-sink fan is working as well, I was always surprised at how many of those things were defective. My E4500 runs at 39-41C all the time with the stock cooler.

So the stock cooler IS running. The case has a clear side with a fan built into the side also. the CPU fan blows right into this one so there should be more than enough heat leaving the case. the heatsink went on perfectly, which leads me to believe it is properly seated. The temps are around 215 F iirc and it shuts off at either 230 or 245 F. I do not have the computer with me currently bu i can post the exact temps and check the seating when i get there tomorrow. I did not apply any thermal paste or grease, so i will look into that also but would that be affecting the temperature readout?

Assuming the temperature probe is reading properly, 215F = 101.6~C so you're about 60C(140F) too high there. The thermal grease wouldn't affect the readout, but it will help with CPU to heat-sink contact and heat transfer. So I would definitely get some thermal grease on there.

I would say 42C too high but thats becuase I use a general threshold of 60C but that is usually what I set the auto off at lol mine wouldn't boot at his temps I would say take a pen light to verify the heatsink just for good measure. I would look into a BIOS update as well to see if it can remedy the bad values. The best would be to try and measure the base of the heatsink with some kind of temperature gauge.

How would i "verify" the heatsink with a penlight? and to update the bios wont i have to "flash the bios" using a floppy or something? there is currently no OS on the HDD and wont the computer auto shutdown part way through the flash? i did some reading online and it sounds like your PC can get really screwy if you mess up a flash. And if anyone has a list of instructions on how to update the BIOS without an OS please post them here TJ

Yes you would have to flash the BIOS your PC is already really screwy and use the pen light to see if light shines through the where the Heatsink and CPU make contact. BIOS update instructions you need should be found on Foxcon's website. I would try thier support line or google to see if this is a common issue with that board.

yeah i spent about an hour on google trying to figure out if it is a common problem but i found no references to it at all. The funny thing is, the person im building the computer with just bought the same mobo for his personal computer and it has the same issue. Im thinking a bugged assembly line.

What is the easiest way to flash a BIOS? Flash drive, CD, or floppy?

At this point I'd try and get a replacement motherboard, if you know of 2 boards with the same issue it's likely some sort of defect. If you picked up the CPU at the same time, see if they'll replace both, they don't like getting that hot & the worst you'll get is a no.

I'm going to try new thermal gel and heatsink positioning but after that I am going for a new mobo. Already contacted support about it.

TJ My solution is much simpler: get a large metal bat, find the person who sold it to you, beat them repeatedly with the bat, then search (the DC varies by salesman) them and get your money back.

Okay its fixed. The heatsink wasnt seated properly. Its now running at a cool 45 C and fully functional. Thanks a lot guys.
