cpu temp...

[Gordon J. Rattray]

Hi there,

On a new machine with an Asus P5800SE motherboard and 3.2 G cpu, the temp
runs at 50- 52 degrees C.

On another 4 months old machine with an Asus P5LD2 with a 3.2 G cpu, the
temp runs at 35 - 37 degrees C.

Both machines read these temps when in "idle" mode, in other words not doing
anything intensively...

What should be normal temps for the P4 775 series cpus?

Thanks,

Gordon

Is the CPU fan running?

Your hardware question is best answered by the manufacturer of the
motherboard and/or Intel (the maker of the CPU). The temp's have nothing to
do with XP. (Also, chekc the motherboard manual for info - can be downloaded
from the Asus web site.)

To keep the noise down some motherboards don't turn on the fans or run them
at reduced rpm below a certain temperature. An Intel board on this system
(915BX) doesn't turn on the cpu fan until the temp hits 55 C.

Better go and catch it!!!

Intel's Kick-Off Menu page for Processor info is found here:

Fans/Rotational Speed, Thermal transfer methods and other
factors are contribute to the CPU temp readings.

I have a P4 dual core 3.2Ghz on an Intel M board. Temp stays in range
54 -57 deg. C the warning temp is 75 deg

It's not really a Windows question, you'd be better going to a relevant
hardware newsgroup.

Those temperatures seem ok as it stands but no load temperatures don't
really tell you what matters.

If you go to the Intel website they have specs for the processors. This
includes the temperatures.
It is the under load temp that is more important than when under no load.
There are utilities to load the processor to get a more representative
temperature.

If the one with the high temp was mine I'd be reducing it- easy way to try
is get some decent heatsink compound (artic silver is good) then remove the
heatsink/fan, clean any old compound off, apply the new compound sparingly-
too much inhibits heat flow- and replace the heatsink/fan. Better is to buy
and fit a better/more efficient heatsink/fan- put new heatsink compound on
sparingly.

Speaking of Temperature monitoring, If anyone needs a tool for their
notebook - check out MobileMeter. A self-contained executable that
can read sensors on most all notebooks. If you download/run don't
be surprised at some of the notebook drive temps you'll see. Some of
these newer 2.5" drives that have faster RPM generate a good bit of
heat.

Your temperatures should be about 10 degrees or more lower. You might
have problems with air flow around the CPU. I upgraded to a P5P800 with
a 3.4 GHz P4 and my idle temperatures were around 60 degrees until I
replaced the case. My old case had less than an inch of clearance
between the CPU and power supply and a lot of the heat was being dumped
into the power supply. After upgrading to a case with about 2 inches of
clearance my idle temperatures dropped to around 40 degrees.

Also look in the bios as many boards vary the rpm of fans depending on how
hot cpu is.

I'd have to agree, it's probably a difference in case design or cooling. I
had a similar situation and swapped cases with a 15 C drop in temperature
both at idle and full load.

 

[Al Brumski]

For what it's worth, I have a similar config, MSI mobo, cooling fan is
an Intel socket 775 cooling fan (round).

reported airflow:
45.5 cfm @ 2500 rpm
~62 cfm @ 3400 rpm

mine rarely exceeds 1200 rpm, target cpu temp is set at 36 C.

no load to heavy load temp ranges from 29 - 33 C.

my power supply is a good 8 inches north of the cpu.

time to chill!!!

I hear they have air conditioned cases for ~ $200.00

What is this world coming to ??

sounds like one machine has a northwood core, the other a prescott.
prescotts run a lot hotter, and are a tad slower overall.

Pentium 4 Northwood Core stock cooling
28c-55c average and 57c worry limit

Pentium 4 Prescott Core stock cooling
45c-70c average and 75c worry limit

both should run near the bottom of their range when idle, top when running
100% (which is rare, unless you're running a burn-in program; even a virus
scan only uses 30% or so. BOINC/SETI can also take cpu utilization to the
100% mark, as can divx encoding etc.).

If you're near the worry limit you have an issue, either bad air flow (if
case internal temps are high too), or a poor heatsink-to-cpu connection or
bad fan. A good test is to drive it to 100% for 60 secs or so, then stop
the load and watch the temp - it should fall RAPIDLY back to the case
temp, say within 45-60 secs. A 10 degree drop in the first 15 secs
indicate the heatsink is doing its job.
