Hot or not?

Been having problem with my new CPU running on the hot side.

First I thought it was real, but after reading some boards I decided to try the following trick:

- let the computer sit (off) overnight, start it up and then right away go into the BIOS and check the CPU temp. That gets me to the CPU temp within the first 10 second after booting up. I did this and the CPU indicated 53 C right away. System temp was 25 C. Computer sits in the basement where the temp is less then 20 C.

My guess is that the CPU temp indicator is off. This is an Opteron 165 dual core CPU.

Any thoughts?

What I've done so far:

- reseated the heat sink, and applied Artic Silver 5 as per the instructions.
- Redid the cabling layout inside the box to make sure airflow was properly running though and not blocking anything.
- case has two 120mm fans, one into the box from the front and one out of the box from the back. Both turning as they should and lots of airflow.

I had two other ideas:
- adding a case fan to the top to allow heat to escape
- buying a new heatsink for the CPU rather then the stock one that came with it.
- CPU fan is blowing onto the heat sink, not pulling from it. Not sure if that is right?

The CPU is right above my PCI express X1800XL 256 Mb grapics card but nothing I can do about that, that is the layout of the board.

But overalll I'm still leaning toward the idea that the temp may be reading wrong. I've not gotten any more crashes that what I expect normal Winblows would give me.......
