P4C800 E-Deluxe & Boxed P4=LOW CPU Fan Speed

[red_hair_swede]

Hi All!

My first venture into the Asus newsgroup.

Finally bit the bullet and moved into the 1000+ Mhz CPU club with a P4C800 E
and P4 3.0 retail boxed CPU.

Install went smooth, and I REALLY enjoy the zippy performance.

Only issue I have, is that after installing Motherboard Monitor to keep tabs
on my new CPU, the CPU temperature gets HOT at times.

I have a nice big case, and the case and motherboard temperature proper are
ok, but under any kind of load, the CPU temperature starts climbing rapidly,
and can get into the 90's, and even briefly over 100 degrees F!

I have the MBM dumping to a monitoring file, so I can see what is happening,
and it seems to come down to the fact that the CPU fan (again stock retailed
boxed Intel Heat sink & Fan) NEVER speeds up, even when the CPU is getting
close to 100F!

I have read all the postings in this group, and seen other postings related
to the boxed Intel Fan, and it seems to be that the CPU Fan itself has
temperature sensing that is controlling things?

My question, should I be concerned?

I DON'T like to see any component getting hot, much less my CPU, so this
does not seem like a good situation.

Thanks,
Nate

1. Disconnect it from the
Q-Fan header if its attached, and run it straight of the MB.

2. Second, double check that your HSF is properly seated, undo and re-do
it is the motto here.

3. Double check in the BIOS that Q-fan is disabled, see section 4-30 in
the manual.

4. Ensure you have MBM runing the proper sensing module, run the ASUS
Probe software, and see if it reports the same values.

Get back to us if the problem is persisting.

As far as cpu temperatures go, 100 degrees F is not considered hot; that's
merely lukewarm and probably close to its idling temperature. At that
temperature, the fan wouldn't be expected to speed up. Somebody please
correct me if I'm wrong, but I don't think there's any cause for concern
unless the temperature gets well over 150-160 F. Once you approach that
temperature, the fan should definitely speed up.

The fan speed increases with motherboard ( internal chasis)
temperature, not that of cpu.

Intel
In addition to the Thermal Monitor feature, the boxed Intel
Pentium 4 processor fan heatsink uses a high quality variable
speed fan which allows the processor to remain within its
operating thermal specifications by running at different
speeds over a short range of internal chassis temperatures.
The processor fan operates at a low speed while internal
chassis temperatures are low. If internal chassis
temperatures increase beyond a lower set point, the fan speed
will rise linearly with the internal chassis temperature
until the higher set point is reached. As fan speed
increases, so does the noise that the fan generates. Systems
should be designed to provide air around the boxed processor
fan heatsink that remains below the lower set point. These
set points, represented in Table 1 and Figure 1 can vary by a
few degrees from fan heatsink to fan heatsink.

Also 100F is 37C
The fan will not increase until ~33C so there is no issue
now.

DOH! you know I read and even replied to this post, and I forgot that
people still use Imperial

Metric rules! 0 = freeze 100 = boil 15 = spring 25C = summer 37C =
person anything above that is 'warming'

Intel P4 CPU's typically run around 37C at idle and up to 45C under load.
That is Normal. You have nothing to worry about.

Hi,

P4C800E-Deluxe, bios 1016, P4C 3.2Ghz, 2GB samsung 3-3-3 3200DDR (dual mode,
PAT activated), ATI 9700(non pro) from sapphire, TV card, hauppauge dvb's
sat card, 4 hard disks (7200 rpm's) and Lian Li PC65 mid tower alu case. By
the way, I have observed that the alu material of the casedon't help at all
to lower case temperature. This is normal because there is no thrmal
conduction between CPU/MB and the case. I don't understand why a conduction
system has not been invented yet (a caloduc ?).

Here are my stats:

Idle: CPU: 33C, MB: 33C, measured by speedfan 4.11.
Full load after 2 hours of sandra sisoft burn test (cpu test only)+flight
simulator 2004: CPU: 49C, MB: 40C (CPU always in 100% load state).

I use zalmann 7000 Cu heatsink, power supply is also from zalmann 400A (very
very quiet). No overclocking.

Now, I use fan speed 4.11 to automatically adjust my fans (2). It works
great. This is the best solution to make the system quiet and cool.

Best regards

Sid
