CPU Temperature Problem?

[Alto101]

I am running an AMD XP2800+ slightly overclocked to 2192MHz but have not changed the default voltage. I have an Antec Sonata II case with one case fan and an Arctic 2L heatsink/fan. The room temperature is a bit warm right now since it is 90+ degrees outside and the air conditioner hasn't been on long enough - 78 degrees F.

I think that the temperature probe for my CPU might be inaccurate. When I turn on my computer after it has been off for several hours and immediately go into the BIOS, the reported CPU temperature is 47 degrees C. After my computer has been on awhile and is idling, the temperature increases to about 52 degrees. Under 100% load, Prime95, it increases to about 59 degrees. Other temperatures seem more reasonable, in the 30-40 degree range. These are as reported by SpeedFan.

Should an XP2800+ be so hot when it is first booted up? The temperature only increases about 12 degrees from the initial to 100% load, so that seems good.

I was very careful to follow the instructions when I applied the Arctic Silver 5. I put a small dab onto the processor and used a credit card to create a thin smooth layer. I have done this several times using ArcticClean each time to clean the surface prior to putting new thermal compound on.

So what I am asking is, do you think that my CPU temperature readings are inaccurate? If not, should I be concerned about the readings that I am getting? I am not experiencing any problems with my system, but I don?t want to in the future either.

I have a Gigabyte GA-7N400 Pro 2 motherboard in case it matters.

Thanks,
Ryan

The only time I've seen my XP below 40C is when I filled the water cooler with cold water, it went to 39C. I think the diodes in them are wonky.

With my 2600+ I'd get ~42C on boot and 55-58 under load. With the 3000+ I'd get ~45C on boot and ~60C under load. The 3000+ was overclocked to nearly 2.4ghz and the 2600+ wouldn't overclock at all. Your temps don't seem abnormal compared to mine.

Notice that you are well within spec for a 2800+ which is rated for a max die temperature of 85C.

The XP2800+ in the Compaq machine I am using idles at around 35C and at full load is 56-58C..

My other 2800+ system I just built idles around 40C I think..I had it running for 5 minutes before I killed the bios

wow, i just put my zalman to the highest rpm, and my 3 ghz prescott is idling at 34. it loads at 49 - 52. wow.

With my GA-7N400 PRO (not the second one) and an Atlon XP 2200, I get about 60C load, or there abouts. I think idle temps are high 40's. However, I used MBM5 to measure the temps. I'd try a different program (such as mbm5) to test the temps.

Yes, make sure you use the one with lowercase letters.
