CPU Temp on New LGA775

[Clayton]

I am a Systems Engineer building and selling computers to my business
customers, all systems prior to yesterday that I sell are Celeron and
Pentium's socket 478 with the ASUS P4S800-MX motherboard, one customer
wanted a system with a SATA harddrive so I ordered the ASUS P5S800-VM LGA775
board with a Celeron D 335J 2.8GHz LGA775 CPU and when I am in the BIOS
setup of the motherboard the CPU Temp reads 70 - 75 degrees is this normal?

Cheers
Clayton

Clayton,

That's fine. Mine's at 87.6 degrees while I type this to you (Enermax System
monitor/card reader) and happy as a clam. If it's not causing any problems
then it's not a problem is it? E

Maybe these LGA775 CPU's are made to with stand heat. always thought a CPU
should be aroung 40 - 45 degrees, I learn something everyday.

It's possible the temperature isn't reported properly.

This is something that is commonly fixed silently in bios updates.

 

[Clayton]

Thanks Jason, I usually do BIOS updates, the update has reduced the CPU temp
to 50 - 55 degrees

Actually, good point. Really... What does the BIOS spit out for info? Does
it change a lot? It *could* be a bad heat sensor... Have you run a burn-in
on it? That was a great idea actually. How are you getting the temp? I read
mine from an Enermax System Monitor device with the card reader (it was a
pain to setup) and that's all I use. It's cheap too! Under $50 USD and worth
every penny though this is the second PC I've installed it to in two months.
(I buy new PCs often.) HDD 1 is currently at 74 degrees and well within
specs. Only two temperature gauges and two fan controls but the pretty blue
lights must count for something! <eg> Actually the whole case is lighted and
when the lights are off the temperature's always almost exactly the same...
86 to 88 degrees. Right now it's hot? It's 87.9... I'm looking for a way to
plot it to printer during a benchmark but can't find one... Ah well.

I am getting my readings from the BIOS hardware monitor, after updating the
BIOS I now get 50 - 55 degrees, I've installed SiSoft and I'm getting a
reading of 40 - 45 degrees

Nice... *gives Jason two thumbs up* Good call, good answer...

I'm American (don't hate me for that) so never asked if it was Celsius or
not. I assumed it was though and knew it was hot but a Celeron and prone to
running hot. My question is, now, is this due to the temp being reported
incorrectly or just plain getting too much voltage?

Wow, this is tough. 9/10 times I'd tell you to rely on the BIOS but with
SiSoft being as reputable as they are I'm now lost. Tell you what? Is it
rebooting for no reason? Smell smoke or ozone? Until you see the smoke from
the Genie being let out of the CPU bottle you're good to go. Actually you're
well within range and I don't see any problems. Make sure the case is free
from obstruction to ensure air flow and the fans are working but really
you're well within specs at either temp.

When I first built my P5P800 I was getting similar temperatures. The
placement of the CPU left no clearance between it and the power supply
so the air flow was totally messed up and the power supply was getting
hot enough to feel through the case. Replacing the case with one with a
couple of inches clearance and more fans fixed the problem. My
temperatures now stay around 40 degrees Centigrade at idle and the low
50s under a heavy load. I am getting the same temperature readings from
the BIOS, Probe, Speedfan, and Sandra. Motherboard Monitor displays the
correct temperatures but the voltage displays were totally wrong.

Another problem.

I have the system going into standby after 30 mins and when I bring the
system out of standby I get a BSOD 0x0000007A Win32k.sys
KERNEL_DATA_INPAGE_ERROR I have already changed the memory to another brand
and still does it, gees I hate this.... any idea's?

 

[Guest]

I have only seen temps over 55 degress when CPUs are overclocked.

I would suggest that the CPU or cooling for it are suspect.

The BSODs would tend to support my statement.

Changing Mobo, memory or Power Supply won't fix the problems as you have
already proven.

Change the CPU or check your cooling system.

I believe it is a reporting problem. I have various temperature reporting
mechanisms on my computer, and they all say something different. The main
issue is what a given measurement does over time. Still, it is nice if that
measurement is more or less accurate. 70 degrees C is 158 degrees F! Ouch.

That'd be pretty warm. My current box is down below 86 F right now according
to the monitor and my HDD1 is at 76.6 which is nice. The temperatures are
always slightly different depending on where I look but always about the
same. I also always use additional fans and giant cases which really makes a
difference I've found. Further reading of the OP's future posts leads me to
think it's still a bit warm.

More important is the actual case in some situations. This motherboard
puts the CPU at the top of the board so if there is no clearance between
it and the power supply (like in a lot of mid-tower cases) you will have
cooling problems. My CPU and fan were fine but there was no way to move
the hot air away from the CPU in my first case. Going to a full tower
eliminated all the problems.

 

[T. Waters]

I agree. 55 C is 131 F.
