Help, Pent D 940 running at 11c

[Steelgrave]

Hi all,

I bought a Pent D 940 and an Asus P5N32-SLI Dlx over the weekend (along with ddr2 ram) and put it together. Everything seems to be working fine except for the cpu temp, which seems way too chilly, 10-11c at idle. Running Super Pi only took it up to 18c. The system temp is 34c, and remains pretty constant there.

Now I realize these Zalman 9500 heat piped coolers work great, but this is obviously off, as there's no way ambient temp in my living room is below 75f (which would be about 22c I believe). If I had to guess I'd say these cpu's should be in the 28-35c range shouldn't they (assuming good cooling)?

I have upgraded the bios to 310, downloaded the latest drivers, and re-seated the heatsink and cpu, all to no avail.

Is this a bad sensor? I've searched a few forums and google and come up short.Any ideas would be appreciated.

Thanks

Check it in the bios when it's running at normal temps by hitting the reset button and going quickly into the hardware monitor section of the bios. Could be a problem with asus probe or your hardware monitor program.

Yeah I did that already, it shows the same temp in the bios and in the asus software under windows.

ahem...excuse me...but do you live in an igloo somewhere in Alaska or in the Northwest territories of Canada? If not..please disregard.

wow, thermal sensors are always wrong, but thats incredible. no idea what to do aside from get a new sensor and use that, but thats kinda cool too.

You seem to have found the 'best-made' pentium ever.!!

You should be frying eggs with your CPU. 11c won't even cook a frog leg ;O

Close, Minnesota. hehehe

if this was mid January and I ran this thing on my patio I could "maybe" see the temps being that low. However since it's in my living room and it was in the 90's here all weekend, heh no way.

Since I had the time last night I returned the mobo and picked up an Intel D975xbx. The temps seem right, but nothing else seems to work on that board. (I should have just gotten another asus I guess)

Why return a mobo just cause of a faulty temp sensor

Sorry, I didn't realize I was wrong in wanting something I just paid a couple hundred bucks for to actually work. Is that really too much to ask?

It's the principal of the thing.

When a thermocouple is hooked up backwards it will read backwards (report hot when it's cold and cold when it's hot). Someone screwed up either the CPU construction or Mobo (i'm not sure how the temp ends up getting reported). Try a known good CPU or mobo if you have one, otherwise RMA one component at a time, that is, unless you don't care.

 

[ElFenix]

aren't the CPU temp sensors in the CPU nowadays?

 

[Kakumba]

depends on the CPU, but I thought most were on the motherboard.

Mine is a Pent D 940, and I believe it's on the Mobo.

I replaced the Mobo last night with a Gigabyte 1975x and temps at idle are now 22c, which is believeable (considering the side panels are off the case and I have a zalman 9500 heat pipe cooler on the cpu).

Excellent choice of a board Flash it to the F4 bios, it bumped my temps up a bit compared to the readings with the F2 bios. I was getting high 20s before at idle and it now is in the mid 30s on the stock cooler.

Its a known problem on the Asus P5N32-SLI & the only way to fix is to send it to support.
Asus forums sheds some light on the subject.

Yep I flashed it to F4 and the cpu temps are now 28-31c, 36-28c under full load. I've heard of some people claiming this board runs rather loud with the fans but I haven't really noticed it.

Yep I saw that, thats what made me decide to just return the board (didn't feel like waiting a few weeks for a mobo).
