Overheating issue

Hey everyone,

I just built my first rig this weekend and I think my processor is overheating. I haven't done anything on the computer except install Win7 ultimate, but my computer is crashing at random intervals. I was able to watch a few movies on it last night after a couple crashes, but this morning I can't even turn the thing on without it getting too hot.

- processor: Intel Core 2 Duo E8500 Wolfdale 3.16GHz 6MB L2 Cache LGA 775 65W Dual-Core Processor
- mobo: MSI P43-C51 LGA 775 Intel P43 ATX Intel Motherboard

I'm using the stock cooling/heating that came with the processor, but I've got a total of 5 fans in my case (which I think are pointed the right way :)). Whenever I boot up into windows, some software that came with my motherboard comes up and tells me that my processor is getting too hot (80-82 C!!) and starts to force a shutdown. I don't know if I've inadvertently changed something or somehow have used MSI's "DOT" to enable some kind of overclocking...

Anyway, here's some monitoring information I pulled out of my BIOS:

CPU Smart FAN Target [55 C]
CPU Min.FAN Speed(%) [87.5]

----- PC Health Status -----
CPU Temperature [82 C / 179 F]
System Temperature [25 C / 77 F]
CPU FAN Speed [1950 RPM]
SYS FAN 1 Speed [0 RPM]
CPU Vcore [1.144 V]
3.3V [3.376 V]
5V [5.129 V]
12V [12.144 V]

If I go to this hardware monitor in my BIOS as soon as I turn the computer on, I can watch the CPU Temperature go from ~55 to 82 at a rate of ~1 degree/sec. Am I missing something? I noticed SYS FAN 1 speed was 0 RPM (and there's nothing plugged into my SYS FAN 1 slot) but I don't see any other cords on the heatsink.

Really hoping someone here can help! I'll be happy to provide any additional details.

Many thanks

Did you apply thermal compound (such as Artic Silver) between the heatsink and CPU?

Did you remember to plug the fan header in? OK, obviously you remembered to. Is the HSF secured tightly?
And SpywareDr, there is TIM already on the base, though it wouldn't hurt to get some MX-3 or MX-2 to replace the normal TIM.
