P4 Cooling?

[MaximK]

I have build P4 system about a month ago. And I?m wondering if this temperature is normal. Personally I don?t think so but what do you think.
I have
P4 1.5G
Intel MB D845WN
DVD-ROM
CD-RW
ATI Radion 64 VIVO
3Com Network Card
Sound blaster Live
?..
The temp reading I in WinXP without any programs running
CPU 32-34C
MB 28-30C
As soon as I start a game like ?Pools or Radiance? the temp jumps by about 5-9C
CPU 39-42C
MB 32-35C
I don?t think I?m getting sufficient cooling.
Any suggestions.
Thanks

I don't have a P4 yet, but your load temps seem to be pretty much in line with what others have been reporting.

Your CPU temperatures are quite low. My P4/1.5 oc to 1.74 will idle at 35-39 deg C and jump to 50-55 under full loads. The case is about 28.

My result is obtained with the Intel retail heatsink. Take a look at the P4 cooler review at VR-Zone Hardware. Even the best cooler can't keep the P4 much below 50 at full load.

yes my p-4 was in those ranges too,
but i drilled case added 3 case fans and now top out at 42 processor under full load.

when i first got computer it kept shutting down for no reason.
then i noticed it was under full load ,that is why i drilled case(directly onto cpu)

no problems since lol

I'm don't have much faith in that VR review. I have looked at the temps on several P4s, wiith several heatsinks. Using CPUcool and MBM5.1 to measure the results and CPUburn and prime to get the load temp up. I have never seen scores nearly as high as VR Zone gets. Their idle temps seem way too high as well, i suspect their temp monitor isn't calibrated properly for P4s or is dodgy like the Asus Probe

Anyway, MaximK, your temps are fine

seems right

What is the basis of your judgement?

If you are using the Intel retail heatsink that comes with the CPU, the performance of this HSF is 0.53C/W. During full load, the P4 consumes more than 60 watts. The rise in CPU core temperature is (or higher):

Temp rise = 60 x 0.53 = 31.8 Deg C.

If your case temperature is 28 Deg C, the CPU core will measure 60 Deg C under load. (60 = 28 + 32)

Since you cannot change the physics or mathematics, any program that measures 40 or so degrees under load cannot be accurate.

If you use more powerful HSF, you can lower the core temperature by some (up to 10 degrees), but probably impossible to get it down to 40 deg without throttling back the CPU. The P4 cooler review at VR-Zone Hardware showed measurements right at this range.

MBM does not detect the hardware monitor integrated circut chip automatically until version 5.1. It is easy for the user or MBM to mis-identify the circuit and resulted in erroreous readings. Also, it usually take quite sometime for MBM to support newly released motherboard. It still does not support the majority of socket 478 P4 MB yet. When set up correctly, the MBM is as good as programs provided by the MB manufacturer such as the Asus Probe, but without the real time monitoring display.
