Hot or not?

[{OF}Flying_Dutchman]

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.......

The temp has always read wrong on my ASUS P5TE. Does the same thing as yours FD, and I know from actual measurements with my certified themometers that it is actually running cool. Of course I upgraded to a copper fin heatsink, etc, etc., then discovered the readings were still high via the board software, then I made my measurements I shoulda made in the first place and discovered I spent alot of time and money I didn't need to, although it was fun installing the heat sink and variable cpu cooling fan speed control.

gman, is that because of the chip or the bios?

Dutch, I have the same CPU, and I don't run that hot, I usually hit about 38-40 c on startup. On load I hit up to 50c but I am OC'd too.

I am on stock cooling as well, which should be more then enough, it is a server class processor and heat sink.

Your motherboard?

Update the BIOS, its amazingly common how often a wrong temperature reading is. 90% of BIOS updates for a motherboard these days seems to contain some temperature error fix. I know mine did, it read about 6C higher than it should for a long time, but after the update it was where my added sensor read.

Capt. That is readings both in BIOS (Setup), and ASUS utility software. BIOS update didn't fix it, but I know for sure the temperatures are actually running lower than the BIOS and ASUS utility software are indicating.

Hey Gman, went and checked mine again for what it is worth, at startup from not being on it is around 28-32c on average.

i thought mine was overheating too
i have an msi kt880 board and an amd athlon XP 2800 (1.25GHz)
it's idling in windows at about 50 deg c and shoots up to 60 when under load (stock heatsink)
i re-seated and everything and it only brought it down around 5 deg c
guess that's a normal operating temp, even though 60 deg c seems a little hottt

AXP's are MUCH hotter than A64s.

yeah my palomino chip athlon xp 2000+ runs 55-60c idle.
